TeKtronix TDS210 Цифровой осциллограф Введение

Оригинал:https://www.cnblogs.com/jamiechen/p/TDS210.html      

Говоря об осциллографе, я считаю, что каждый, кто изучает электронные коммуникации, должен быть знаком с ним, и он также является незаменимым вспомогательным инструментом в области разработки встраиваемых продуктов. Когда люди (включая меня) часто используют осциллограф после долгого периода времени, неизбежно, что они оглушат «Где находится интерфейс для переключения постоянного тока в переменный»? Проблема, поэтому я думаю, что для записи все еще необходимо выполнить несколько простых операций, ведь память не так хороша, как плохая ручка ~~~

При написании этого блога я ссылался на резюме многих пользователей сети, и я хотел бы поблагодарить вас!

    

I. Основные операции:

1. Область отображения

В дополнение к осциллограммам область отображения также содержит множество инструкций по осциллограммам и настройкам управления прибором.

                          

1. Существует три различных графических представления, соответствующих различным методам сбора данных: метод выборки, метод обнаружения пиков и метод усреднения.

2. Состояние триггера указывает на следующую информацию:

Постановка на охрану: осциллограф собирает данные до запуска, в это время все триггеры будут игнорироваться.

Готов: все данные предварительного запуска получены, и осциллограф готов к принятию сигналов запуска.

Trig’d: Осциллограф обнаружил триггер и собирает информацию после триггера.

Авто: осциллограф находится в автоматическом режиме и получает сигналы без запуска.

• Сканирование: осциллограф непрерывно получает и отображает данные формы сигнала в режиме сканирования.

• Стоп: осциллограф прекратил получать сигналы.

3. Указатель указывает на горизонтальное положение триггера, а ручка управления горизонтальным положением может регулировать его положение.

4. Показание показывает временное отклонение между горизонтальным положением триггера и центральной линией экрана, которое равно 0 в центре экрана.

5. Указатель указывает уровень триггера.

6. Показание указывает значение уровня триггера.

7. Выбранный тип триггера обозначен значком. Существует несколько типов: триггер с нарастающим фронтом, триггер с падающим фронтом, видеосигнал с линейной синхронизацией, видеосигнал с синхронизацией поля

8. Показание указывает настройку времени окна.

9. 9. Показание указывает установленное значение основной временной базы.

10. Показание показывает установленное значение основной временной базы.

11. Показание показывает вертикальный масштабный коэффициент канала.

12. В области отображения кратко отображается онлайн-информация.

13. Указатель на экране указывает наземную контрольную точку отображаемого сигнала. Если указатель на канал отсутствует, это означает, что канал не отображается.

Кроме того, существует три различных формы отображения в зависимости от типа сигнала: черная линия, серая линия и пунктирная линия.Сплошная черная линияФорма сигнала представляет активную отображаемую форму сигнала. После того, как получение остановлено, форма сигнала будет оставаться черной, пока контрольное значение, которое вызывает неопределенность точности отображения, остается неизменным.

После того, как получение остановлено, вертикальные и горизонтальные контрольные значения могут быть изменены. Опорный сигнал и сигнал, используя функцию длительности отображенияСерые линииДисплей.Пунктирная форма волныТочность отображения формы сигнала является неопределенной. Причиной пунктирной линии является то, что значение настройки управления изменяется после остановки сбора данных, но прибор не может соответствующим образом изменить форму сигнала дисплея, чтобы соответствовать ей. Например, когда сбор данных остановлен, изменение контрольного значения триггера приведет к пунктирной форме волны.

Во-вторых, область кнопок управления

В верхней части панели осциллографа расположена область кнопок управления, всего 9 кнопок:

         

1. SAVE / RECALL (сохранение / возврат): отображение меню функций сохранения / возврата, которое используется для настройки сохранения и вызова инструмента или формы сигнала. Состояние настройки осциллографа сохраняется в постоянной памяти. Когда осциллограф включен, заданное значение восстанавливается до того состояния, в котором оно находилось в последний раз. Пользователь также может вызвать заводское предустановленное состояние для настройки осциллографа.

2. ИЗМЕРЕНИЕ: отображение меню функций автоматического измерения.Может быть достигнуто5 видов автоматического измерения и могут отображать 4 из них одновременноРезультаты измерений, При измерении сначала нажмите кнопку в верхнем окне меню, чтобы выбрать меню «Источник» или «Тип». Измеряемый канал можно выбрать из меню «Источник», а тип измерения (частота, период, среднее значение, от пика до пика и т. Д.) Можно выбрать из меню «Тип».

3. ACQUIRE: отображение меню функции сбора данных для установки метода сбора данных. Существует три метода сбора данных: выборка, обнаружение пиков и усреднение. Предустановленный режим — это режим сэмплирования.

     4.AUTOSET(Автоматическая настройка): Функция автоматической настройки может автоматически настраивать различные значения управления для создания отображения сигнала, подходящего для наблюдения. Например, метод сбора, горизонтальное положение, тип триггера, метод триггера и т. Д. Опыт личного использования: если отображаемая форма волны не соответствует ожиданиям после включения питания, вы можете напрямую нажать эту кнопку, чтобы автоматически настроить осциллограф, а затем точно настроить его на нужную вам настройку.

5. UTILITY (Вспомогательная функция): с помощью этой кнопки вы можете просматривать состояние системы и состояние неисправности, а также выполнять самокоррекцию и выбирать язык отображения.

6. CURSOR (курсор): Используйте эту кнопку для отображения меню функций курсора. С помощью пункта меню «Тип» вы можете выбрать содержание измерения, например «Напряжение» для измерения амплитуды и «Время» для измерения времени и частоты, с помощью пункта меню «Источник» вы можете выбрать канал 1, канал 2, математическое значение, Обратитесь к A и т. Д.

Примечание. При нажатии кнопки CURSOR на дисплее появляются два пунктирных курсора, и положение курсора можно регулировать с помощью ручки управления вертикальным смещением. Когда другие кнопки используются для вызова соответствующего функционального меню, курсор все равно будет отображаться, но его невозможно отрегулировать.

7. 7. DISPLAY (дисплей): эта кнопка может вызвать меню функций дисплея, в котором можно выбрать режим отображения формы сигнала и отрегулировать контрастность дисплея.

8. 8. HARDCOPY (печатная копия): используйте эту кнопку для печати печатной копии отображаемого изображения. Но нужно установить модуль расширения с RS-232 и другими портами и подключить к принтеру.

9. 9. RUN / STOP (запуск / остановка): используйте эту кнопку для запуска и остановки сбора сигналов.

3. Область кнопки управления триггером

Область кнопок расположена на правой стороне панели. Есть 4 кнопки и 1 ручка.

               

1. 1. МЕНЮ ТРИГГЕРА: используйте кнопку «МЕНЮ ТРИГГЕРА», чтобы вызвать меню выбора режима триггера. Существует два режима триггера: граничный триггер и видео-триггер. Каждый режим триггера соответствует отдельному пункту функционального меню. Пользователь может выбрать соответствующую кнопку для настройки в соответствии с фактической ситуацией ,

2. SET LEVEL TO 50%: Используйте эту кнопку, чтобы установить уровень триггера в вертикальной средней точке амплитуды триггерного сигнала.

3. FORCE TRIGGER: эта кнопка может гарантировать, что независимо от того, достаточно ли триггерного сигнала, она автоматически начнет сбор данных. Когда выборка остановлена, эта кнопка недействительна.

4. ПРОСМОТР ТРИГГЕРА: После нажатия этой кнопки исходная форма сигнала, отображаемая на экране, заменяется формой сигнала источника триггера, чтобы вы могли просматривать настройки триггера и их влияние на сигнал триггера.

5. Регулятор LEVEL / HOLD OFF: этот регулятор выполняет две функции.

Как кнопка управления уровнем запуска по фронту, она может установить амплитуду, которую должен пройти сигнал запуска, чтобы облегчить обнаружение;

Как кнопка управления деблокированием, она может установить значение времени перед принятием следующего события триггера, пожалуйста, обратитесь к содержанию о «отпускании», описанному позже.

4. Горизонтальная / вертикальная область кнопок управления

           

1. 1. Вертикальная область кнопок управления (ВЕРТИКАЛЬНАЯ)

(1) Используйте вертикальную кнопку управления (положение), чтобы отрегулировать положение и вертикальный масштаб сигнала и установить входные параметры.

(2) Регулятор VOLTS / DIV: при использовании кнопки «Старт / Стоп» для остановки регистрации сигнала используйте этот регулятор для регулировки амплитуды сигнала по вертикали.

(3) Используйте кнопку «CH1 / CH2 menu» для отображения формы сигнала входного сигнала и вызова соответствующего функционального меню, в котором можно регулировать чувствительность регулятора «VOLTS / DIV» (то есть грубую / точную настройку), и Установите предел пропускной способности и отрегулируйте коэффициент затухания зонда.

          (4)MATHКнопка меню: используйте эту ручку для вызова меню числовых функций, которое может отображать в обратной фазе и регулировать суперпозицию и вычитание сигналов различных каналов.

2. Горизонтальная область кнопок управления (ГОРИЗОНТАЛЬНО)         

(1) Используйте горизонтальную ручку управления (положение), чтобы отрегулировать горизонтальное положение формы сигнала всех каналов и изменить горизонтальную шкалу Расширить или заключить договор. Горизонтальное положение изменяет положение сигнала относительно точки запуска.

(2) Регулятор SEC / DIV (секунд / деление): при использовании кнопки «Старт / Стоп» для остановки регистрации сигнала используйте этот регулятор для регулировки горизонтальной амплитуды сигнала.

(3) ГОРИЗОНТАЛЬНОЕ МЕНЮ: Используйте эту кнопку, чтобы установить область окна (используйте подсказку внизу дисплея при ее использовании), а также отрегулировать уровень запуска и время удержания.

V. Площадь разъема

        

     1. PROBE COMP (компенсация датчика): Когда датчик подключается к любому входному каналу в первый раз, можно выполнить настройку компенсации датчика, чтобы согласовать его с входным каналом. Метод заключается в следующем:

(1) Подключите датчик осциллографа к каналу CH1, затем подключите наконечник датчика к 5-вольтовому разъему «PROBE COMP (компенсация датчика)» и подключите опорный провод датчика к его заземлению.

(2) Нажмите кнопку «CH1 MENU», чтобы активировать канал CH1, а затем нажмите кнопку «AUTOSET».

(3) Проверьте форму отображаемого сигнала и отрегулируйте датчик в соответствии с ситуацией.

     2. CH1, CH2 (канал 1, канал 2): входной разъем, необходимый для отображения формы сигнала соответствующего канала.

     3. EXT TRIG (External Trigger): входной разъем, необходимый для внешнего источника запуска. Вы можете использовать меню функций запуска для выбора источника запуска.

Серия TDS210 предлагает четыре типа пунктов меню: Круговая форма, кнопка действия, переключатель и выбор страницы, пожалуйста, обратите внимание при работе.

                        

     1. Круглая форма: сверху находится заголовок, а форма выбора отображается в обратном порядке. Например, при нажатии кнопки меню CH1 первая кнопка в меню CH1 будет переключаться между вариантами вертикальной связи.

     2. Меню кнопки действий: может отображаться название действия. Например, увеличить или уменьшить контраст с помощью кнопки «DISPLAY» на панели управления.

     3. Меню радиокнопок: например, с помощью кнопки «ACQUIRE» на панели управления можно выбрать три различных метода сбора данных: выборка, обнаружение пика и среднее значение, а также количество выборок.

     4. Меню выбора страницы: окно меню выбора страницы содержит два элемента меню для каждой кнопки на передней панели, а выбранные элементы меню отображаются в обратном порядке.

II. Несколько советов: 

1. Быстро установите сигнал захвата:

После подключения проводов осциллографа сначала нажмите [AUTOSET] в [области кнопок управления], чтобы осциллограф установился автоматически, а затем выполните точную настройку после вывода сигнала;

2. Захват спорадических последовательностей или импульсов:

(Как и в первой области отображения изображения) «режим триггера» изменен на [один триггер];

III Примечания:

1. Введение в цифровой осциллограф TeKtronix TDS210

TDS 210 — это небольшой портативный цифровой осциллограф реального времени с полосой пропускания 60 МГц, каждый канал имеет частоту дискретизации 1 Гс / с и длину записи 2500 точек, двойную временную базу, функцию видеосигнала, с портами связи RS232, GPIB, Centronics.

1. Триггер

Триггер определяет, когда осциллограф начинает собирать данные и отображать сигналы.

Когда осциллограф начинает собирать данные, сначала соберите достаточно данных, чтобы нарисовать форму сигнала слева от точки запуска.Осциллограф непрерывно собирает данные, ожидая возникновения условия запуска. Когда триггер обнаружен, осциллограф непрерывно собирает достаточно данных, чтобы нарисовать форму волны справа от точки запуска.

2. Источник (источник запуска)

Существует три основных способа запуска: входной канал, сеть и внешний запуск.

(1) Входной канал: Наиболее часто используемым источником запуска в трех режимах является входной канал.В качестве источника запуска можно выбрать один из каналов 1 (CH1) или канал 2 (CH2) в соответствии с фактическими потребностями.

(2) Городское питание: этот источник запуска можно использовать для отображения частотной зависимости между сигналом и мощностью, например, осветительным оборудованием и оборудованием электропитания. Осциллограф сгенерирует триггер без ручного ввода триггерного сигнала.

(3) Внешний триггер: Этот источник триггера может использоваться для сбора данных по двум каналам и триггера входа на третьем канале одновременно. Например, в качестве источника запуска могут использоваться внешние часы или сигнал от тестируемой цепи. При подключении вы можете подключить внешний источник запуска к разъему EXT TRIG.

3. Тип триггера

Существует два типа триггеров: граничный триггер и видео триггер.

Запуск по фронту: Аналоговые и цифровые тестовые схемы могут использоваться для запуска по фронту. Когда триггерный вход проходит заданный уровень в заданном направлении, происходит запуск по фронту.

Запуск по видео: Стандартные видеосигналы можно использовать для запуска по полю или по линии.

4. Режим триггера

Режим запуска определяет поведение осциллографа в случае отсутствия события запуска. Есть три режима триггера: автоматический, нормальный и одиночный триггер.

(1) Автоматический запуск: этот режим запуска позволяет осциллографу получать сигнал, даже если условие запуска не обнаружено. Когда осциллограф не запускает условия в течение определенного времени ожидания, осциллограф выполняет принудительный запуск. При принудительном запуске неверного запуска осциллограф не может синхронизировать сигналы, и отображаемые сигналы будут свернуты вместе. Когда происходит эффективный запуск, форма сигнала на дисплее стабильна.

(2) Нормальный триггер. В режиме нормального триггера осциллограф может получать сигнал только при его запуске. Когда триггера нет, осциллограф отобразит исходную форму волны и не получит новую форму волны.

(3) Одиночный триггер. В режиме одиночного триггера каждый раз, когда пользователь нажимает кнопку «Выполнить», осциллограф обнаруживает триггер и получает сигнал.

5. Рельеф

В течение времени удержания (промежуток времени после каждого захвата) триггер не может быть распознан. Для получения стабильной формы сигнала дисплея для некоторых сигналов необходимо настроить время задержки.

Сигнал запуска может представлять собой сложную форму сигнала со многими возможными точками запуска, например цифровую последовательность импульсов. Даже если форма сигнала сложная, простой триггер может привести к тому, что на дисплей выводится серия шаблонов вместо одного и того же шаблона каждый раз.

Период задержки может использоваться для предотвращения запуска импульсов, отличных от первого импульса в последовательности импульсов. Таким образом, осциллограф всегда будет отображать только первый импульс.

Чтобы получить управление удержанием, нажмите кнопку «HORIZONTAL menu», выберите «Release» и используйте ручку «Release», чтобы изменить время удержания.

6. Сцепление

Связь триггера определяет, какие компоненты сигнала передаются в схему триггера. Типы триггерной связи включают в себя постоянный, переменный ток, подавление шума, подавление высоких частот и подавление низких частот.

DC: DC связь позволяет всем компонентам пройти.

AC: переменная связь предотвращает прохождение компонентов постоянного тока.

Подавление шума: Соединение с подавлением шума снижает чувствительность триггера и требует более высокой амплитуды сигнала для формирования стабильного триггера, тем самым уменьшая вероятность ложного срабатывания сигнала при шуме.

Высокочастотное подавление: высокочастотная подавляющая связь предотвращает прохождение высокочастотной части сигнала и позволяет пропускать только низкочастотные компоненты.

Низкочастотное подавление: низкочастотная подавляющая связь предотвращает прохождение низкочастотной части сигнала и позволяет пропускать только высокочастотные компоненты.

7. Позиционирование

Кнопка управления горизонтальным положением устанавливает отклонение времени между триггером и центром координат экрана.

Во-вторых, собирать данные

При получении аналоговых данных осциллограф преобразует их в цифровую форму. Существует три различных способа сбора данных: выборка, обнаружение пиков и среднее значение. Настройка временной базы влияет на скорость сбора данных.

1, образец: в режиме сбора данных, осциллограф в соответствии с образцами опорного сигнала равные промежутки времени, чтобы восстановить форму волны. Этот метод может в основном представлять большинство аналоговых сигналов. Однако он не может получить быстрые изменения аналогового сигнала в двух временных интервалах дискретизации, которые могут вызвать ошибки и потерять узкие импульсы в сигнале. Чтобы решить вышеупомянутую ситуацию, следует использовать метод обнаружения пикового обнаружения.

2. Обнаружение пиков: в этом режиме сбора данных осциллограф собирает максимальные и минимальные значения входного сигнала в каждом интервале дискретизации и отображает форму волны с выборочными данными. Таким образом, узкие импульсы, которые могут быть потеряны в режиме выборки, могут быть получены и отображены, но шум будет более очевидным.

3. Среднее значение: в этом режиме сбора данных осциллограф получает несколько сигналов, затем усредняет их и отображает усредненные сигналы. Этот метод можно использовать для уменьшения случайного шума.

Кроме того, настройка времени будет влиять на скорость сбора данных. Вы можете использовать ручку «секунды / деление», чтобы настроить временную шкалу на определенный горизонтальный масштаб в соответствии с потребностями пользователя.

В-третьих, масштаб и позиционирование формы волны

Регулируя масштаб и положение сигнала, можно изменить отображение на экране. При изменении масштаба размер отображаемого сигнала будет увеличен или уменьшен. Когда положение меняется, сигнал будет двигаться вверх, вниз, влево и вправо.

Индикатор ссылки на канал (расположенный слева от сетки) показывает каждую отображаемую форму сигнала. Индикатор показывает уровень земли записи сигнала.

1. Вертикальный масштаб и положение

Вертикальное положение отображаемого сигнала может быть изменено путем перемещения сигнала вверх и вниз. Чтобы сравнить данные, вы можете выровнять сигнал вверх и вниз.

При изменении масштаба сигнала по вертикали отображаемый сигнал будет уменьшаться или расширяться относительно уровня земли.

2. Горизонтальный масштаб и положение, предварительная информация

До и после запуска данные формы сигнала можно просмотреть, отрегулировав кнопку управления «горизонтальное положение». Изменение горизонтального положения формы сигнала фактически изменяет временное отклонение между триггером и центром области отображения (что приведет к смещению формы сигнала влево или вправо в пределах области отображения).

3. неразбериха

Когда скорость выборки осциллографа низкая и форма сигнала не может быть восстановлена ​​правильно, форма сигнала будет сбита с толку. При возникновении путаницы отображаемая частота сигнала будет ниже фактической частоты входного сигнала, или сигнал не будет стабильным, даже если сработал осциллограф.

Один из способов проверить наличие путаницы — использовать ручку «секунды / деление» для медленного изменения горизонтальной шкалы. Если форма волны резко меняется, текущая форма волны может быть ошибочной.

Чтобы правильно представить сигнал и избежать путаницы, частота дискретизации сигнала должна быть не ниже, чем в два раза выше самой высокой частоты сигнала. Если сигнал имеет компонент с частотой 5 МГц, для сигнала в секунду необходимо собрать 10 триллионов выборок или более.

Четыре, измерение

График зависимости напряжения от времени, отображаемый на осциллографе, можно использовать для измерения отображаемого сигнала. Есть много методов для проведения измерений, таких как график сетки, курсор или автоматическое измерение.

1. Клетчатый график

Этот метод может быть использован для быстрой и интуитивной оценки и может быть просто измерен путем деления графика сетки и масштабного коэффициента. Если максимальный и минимальный пики формы сигнала занимают 5 больших сеток вертикальной сетки, а масштабный коэффициент равен 100 мВ / дел, напряжение между максимальным и минимальным пиками сигнала составляет: 5 дел × 100 мВ / дел = 500 мВ.

2. курсор

Этот метод позволяет пользователю измерять, перемещая курсор. Курсоры всегда отображаются парами, и отображаемое значение является измеренным значением. Существует два типа курсоров: напряжение и время.

Курсор напряжения: Курсор напряжения отображается в виде горизонтальной линии, которая используется для измерения параметров в вертикальном направлении.

Курсор времени: Курсор времени отображается в виде вертикальной линии и используется для измерения параметров в горизонтальном направлении.

3. Автоматическое измерение

В режиме автоматического измерения осциллограф автоматически выполняет все расчеты. Поскольку этот вид измерения использует формы волны для записи точек, он имеет более высокую точность, чем автоматическое измерение сетки и измерений курсора.

Автоматическое измерение отображает результаты измерений с показаниями, и показания периодически изменяются с новыми данными, собираемыми осциллографом.

В-пятых, вам часто нужно использовать три функции при настройке осциллографа.

1. Автоматическая настройка

Функция автоматической настройки может автоматически регулировать горизонтальную и вертикальную калибровку, связь триггера, тип, положение, наклон, уровень и настройки режима для получения стабильного отображения формы сигнала.

2. Сохранить настройки

В случае запланированных настроек, осциллограф будет сохранять настройки каждый раз, когда он будет закрыт, и осциллограф будет автоматически вызывать настройки при его включении. Пользователь также может сохранить пять настроек в памяти осциллографа и изменить их в любое время.

Примечание. После изменения настроек подождите 5 секунд, прежде чем выключать осциллограф, чтобы убедиться, что новые настройки сохранены правильно.

3. Напомним настройки

Осциллограф может вызывать любой вид сохраненных настроек или предустановленных заводских настроек.

4. Предустановка (заводская настройка)

Перед отправкой с завода осциллограф был предварительно настроен на различные нормальные операции, и пользователь может в любой момент восстановить заводские настройки при необходимости.

Chance favors the prepared mind.

на работе посмотрю ссылку, а сейчас просто нагуглил вот что: http://www.bay.ru/

кстати, а каких годов эти осциллографы?

Нет, я посмотрел этот bay.ru — это не вариант. они цену накручивают вдвое :( Уж дешевле самому купить и растаможить.

Obtaining a waveform display is dependent on many instrument
settings. Once you obtain a waveform, you can take your measure-
ments. But the appearance of these waveforms also provides key
information about the waveform.
Depending on the type, waveforms will be displayed in three
different styles: black, gray, and broken.

1. A solid black waveform indicates a live waveform display. The
waveform remains black when the acquisition is stopped if no
controls are changed that makes the display accuracy uncertain.
Changing the vertical and horizontal controls is allowed on
stopped acquisitions.
2. Reference waveforms and waveforms with persistence applied
appear gray.
3. A broken line appearance indicates the waveform display
accuracy is uncertain, This is the result of stopping the acquisi-
tion and then changing a control setting that the instrument
cannot modify the displayed waveform to match. For example,
changing the trigger controls on a stopped acquisition causes a
broken-line waveform.

Normal and Auto Mode. Use Normal trigger mode to trigger only on a
valid trigger. Use Auto trigger mode to let the acquisition free-run in
the absence of a valid trigger. Auto allows an untriggered, scanning
waveform at 100 ms/div or slower time base settings.
Single Mode. Use Single trigger mode to capture a single acquisition
of an event. The content of a single acquisition sequence depends on
the acquisition mode.

Coupling. Coupling allows you to filter the trigger signal used to
trigger an acquisition.
AC blocks the DC component.
DC passes all components of the signal.
Noise Reject passes all components of the signal but increases the
peak-to-peak signal required.
HF Reject attenuates the high-frequency components above
80 kHz.
LF Reject blocks the DC component and attenuates the
low-frequency components below 30 kHz.
Pretrigger. The trigger position is typically set at the horizontal center
of the screen. In this case you are able to view five divisions of
pretrigger information. Adjusting the Horizontal Position of the
waveform allows you to see more or less pretrigger information.
Trigger View. Pushing TRIGGER VIEW displays the trigger waveform
until the button is released.
When displaying the trigger acquisition, all front-panel buttons are
disabled except HARDCOPY.

AC Coupling
A mode that blocks the DC component of a signal but passes the
dynamic (AC) component of the signal. Useful for observing an С
AC signal that is normally riding on a DC signal.
Acquisition
The process of sampling signals from input channels, digitizing
the samples, processing the results into data points, and
assembling the data points into a waveform record. The
waveform record is stored in memory.
Aliasing
A false representation of a signal due to insufficient sampling of
high frequencies or fast transitions. A condition that occurs
when an oscilloscope digitizes at an effective sampling rate that
is too slow to reproduce the input signal. The waveform
displayed on the oscilloscope may have a lower frequency than
the actual input signal.
Attenuation
The degree the amplitude of a signal is reduced when it passes
through an attenuating device such as a probe or attenuator (the
ratio of the input measure to the output measure). For example,
a 10X probe attenuates, or reduces, the input voltage of a signal
by a factor of 10.
Auto Trigger Mode
A trigger mode that causes the oscilloscope to automatically
acquire if it does not detect a triggerable event.
Average Acquisition Mode
A mode in which the oscilloscope acquires and displays a o
waveform that is the averaged result of several acquisitions.
This reduces the apparent noise. The oscilloscope acquires data {
as in the sample mode and then averages it according to a
specified number of averages.

Cursors
Paired markers that you can use to make measurements between
two waveform locations. The oscilloscope displays the values
(expressed in volts or time) of the position of each cursor and
the distance between the two cursors.
DC Coupling
A mode that passes both AC and DC signal components to the
circuit. Available for both the trigger system and the vertical
system.
Digital Real Time Digitizing
A digitizing technique that samples the input signal with a
sample frequency of at least four times the oscilloscope
bandwidth. (The TDS 210 and TDS 220 samples at least 10
times the bandwidth.) Combined with (sinx)/x interpolation, all
frequency components of the input up to the bandwidth are
accurately displayed.
Digitizing
The process of converting a continuous analog signal such as a
waveform to a set of discrete numbers representing the
amplitude of the signal at specific points in time.
Display
The word used to refer to the screen or the LCD (liquid crystal
display).
Edge Trigger
Triggering that occurs when the oscilloscope detects the source
passing through a specified voltage level in a specified direction
(the trigger slope).

Holdoff
A specified amount of time that must elapse after a trigger
signal before the trigger circuit will accept another trigger
signal. Holdoff helps ensure a stable display.
Voltage Cursors
The two horizontal bars that you position to measure the voltage
parameters of a waveform. The oscilloscope displays the value
of each cursor with respect to ground and the voltage value
between the bars.
Menu
A set of labels shown in the display to identify the functions of
the bezel buttons. The specific menu contents depend on the -

Normal Trigger Mode
A mode where the oscilloscope does not acquire a waveform
record unless a valid trigger event occurs. It waits for a valid
trigger event before acquiring waveform data.
Peak Detect Mode
A mode in which the oscilloscope creates a pair of record points
during each sample interval. Each pair consists of the maximum
and minimum input voltage during the interval.
Persistence
A method of retaining old data on the display for a period of
time.

Reference Waveform
A saved waveform selected for display. You can display two
reference waveforms as Wim A and Wim B.
RS-232
The serial communication port used to connect to a hard-copy
device, computer, controller, or terminal.
Sample Acquisition Mode
A mode in which the oscilloscope creates a record point by
saving a sample during each acquisition interval.
Sample Interval
The time interval between successive samples in a time base.
For real-time digitizers, the sample interval is the reciprocal of
the sample rate.
Sampling
The process of capturing an analog input, such as a voltage, at a
discrete point in time and holding it constant so that it can be
quantized.
Scan Mode
An acquisition mode useful at slow horizontal scale settings.
Scan mode allows you to view the waveform as it is acquired
point-by-point. The waveform appears from left to right across
the display.

Self Calibration

The self calibration routine lets you quickly optimize the oscilloscope signal path

for maximum measurement accuracy. You can run the routine at anytime but you

should always run the routine if the ambient temperature changes by 5_ Cor

more.

To compensate the signal path, disconnect any probes or cables from the channel

input connectors. Then, press the UTILITY button and select Do Self Cal to

confirm that you are ready to proceed.

Probe Safety

A guard around the probe body provides a finger barrier for protection from

electric shock.

Finger guard

WARNING. To avoid electric shock when using the probe, keep fingers behind the

guard on the probe body.

To avoid electric shock while using the probe, do not touch metallic portions of

the probe head while it is connected to a voltage source.

Connect the probe to the instrument and connect the ground terminal to ground

before you take any measurements.

Probe Attenuation Setting

Probes are available with various attenuation factors which affect the vertical

scale readout of the oscilloscope.

To change (or check) the probe attenuation setting, press the VERTICAL MENU

button (of the channel youre using) and then press the menu selection next to

Probe until the correct setting is displayed.

This setting remains in effect until changed again.

NOTE. The default Probe menu attenuation setting is 10X when the oscilloscope

is shipped.

Be sure that the Attenuation switch on the P2100 probe is set to match the Probe

menu selection in the oscilloscope. The probe switch settings are 1X and 10X.

Attenuation switch

NOTE. When the Attenuation switch is set to 1X, the P2100 probe limits the

bandwidth of the oscilloscope to 7 MHz. To use the full bandwidth of the

oscilloscope, be sure to set the switch to 10X.

Theory of Operation

This chapter describes the electrical operation of the TDS 200-Series Digital

Real-Time Oscilloscope to the module level. It describes the basic operation of

each functional circuit block shown in figures 3-1 and 3-2.

Main Board

The Main board contains a two or four channel acquisition system, trigger

system, acquisition/display controller, and system processor. Interfaces are

provided for two signal inputs, external trigger input, probe compensation, front

panel, LCD display, extension module, and power supply. Acquisition and

display functions are implemented in two application specific integrated circuits

(ASICs).

Signals from the CH 1, CH 2, and EXT TRIG, or CH 1, CH 2, CH 3, and CH 4

input connectors pass through attenuators to the acquisition ASIC. The acquisi-

tion ASIC contains amplifiers and samplers for each input channel, A/D

converter, and trigger logic. The digitized waveform samples are transferred to

the display ASIC. Low voltage regulators supply isolated power to the acquisi-

tion ASIC.

The display system consists of the display ASIC, DRAM memory, and system

oscillator. Digitized acquisition samples are processed by the display ASIC and

stored into DRAM. The Display ASIC formats the waveform data and generates

drive signals for the LCD display. Front panel scanning is also performed by the

display ASIC.

The processor system consists of the microprocessor and memory. The processor

system interprets the front panel controls, programs acquisition and display

parameters, computes waveform measurements, and manages the extension

module interface. Saved setups, waveforms, and calibration constants are stored

in nonvolatile memory. The processor system shares DRAM with the display

system.

BNC connectors are mounted on the main board for the CH 1, CH 2, and trigger

or CH 1, CH 2, CH 3, and CH 4 inputs. The signal inputs are compatible with the

P2100 probes supplied.

The PROBE COMP and ground terminals are provided for probe adjustment.

TDS 200 Series Digital Oscilloscope Service Manual

Power Supply

The power supply module generates low voltage DC, a line trigger signal for the

main board, and high voltage AC to power the LCD backlight. The power supply

operates over a wide power line voltage and frequency range.

Display Module

The display module consists of a liquid crystal display (LCD), a display driver,

and a florescent backlight.

Front Panel

The front panel board holds the encoders and push button contacts that the

operator uses to control the instrument. An elastomer mat holds the conductive

pads for the push buttons. Circuits on the front panel convert the matrix into

serial data which is read by the display ASIC on the main Board.

Extension Modules

Each extension module also contains a GPIB, RS-232, and Centronics parallel

printer interface. A ROM on the extension module contains processor instruc-

tions to support the communications interfaces. Extension modules interface with

the processor system through the extension module port connector.
