Chapter 1 Programming Overview

To Build Remote Communication

You can build the remote communication between DP800 and PC over USB, LAN, RS232 or GPIB (option, can be extended via the USB-GPIB interface converter) interface.

Note: The end mark of the command sent through RS232 interface is «rn».

Operation Steps:

1Install the Ultra Sigma common PC software

You can acquire this software from the resource CD in the standard accessories or download it from RIGOL official website (www.rigol.com) and then install it according to the instructions.

2Connect the instrument and PC and configure the interface parameters of the instrument

DP800 supports USB, LAN, RS232 and GPIB (extended via the USB HOST interface of the instrument) communication interfaces, as shown in the figure below.

LAN USB DEVICE

RS232

USB HOST

Figure 1-1 DP800 Communication Interfaces

Note: For DP831A/DP832A/DP821A/DP811A, the instrument is installed with the LAN and RS232 options when it leaves factory; users can build the remote communication between the instrument and PC via the LAN or RS232 interface directly. For DP831/DP832/DP821/DP811, the LAN interface communication and RS232 interface communication are optional functions; to use the functions, please order the corresponding option and install the option correctly (:LIC:SET).

(1)Use the USB interface: connect the USB DEVICE interface at the rear panel of DP800 and the USB HOST interface of the PC using USB cable.

(2)Use the LAN interface:

Make sure that your PC is connected to the local network.

Check whether your local network supports DHCP or auto IP mode. If not, you need to acquire the network interface parameters available, including the IP address, subnet mask, gateway and DNS.

Connect DP800 to the local network using network cable.

Press Utility I/O Config LAN to configure the IP address, subnet mask, gateway and DNS of the instrument.

1-2

DP800 Programming Guide

Chapter 1 Programming Overview

RIGOL

(3)Use the RS232 interface:

Connect the RS232 interface with the PC or data terminal equipment (DTE) using RS232 cable.

Press Utility I/O Config RS232 to set interface parameters (such as the baud rate and parity) that match the PC or terminal equipment.

(4)Use the GPIB interface:

Use the USB-GPIB interface converter to extend a GPIB interface via the USB HOST interface at the rear panel of DP800.

Connect the instrument with your PC using a GPIB cable.

Press Utility I/O Config GPIB to set the GPIB address of the instrument.

3Check whether the connection is successful

Run the Ultra Sigma, search for resource, right-click the resource name and select «SCPI Panel Control» in the pop-up menu. Enter the correct command in the pop-up SCPI control panel and click «Send Command» and then «Read Response» or click «Send & Read» directly to check whether the connection is successful.

Remote Control Methods

1User-defined Programming

You can program and control the instrument using the SCPI (Standard Commands for Programmable Instruments) commands listed in chapter 2 «Command System» in various development environments (such as Visual C++, Visual Basic and LabVIEW). For details, refer to the introductions in chapter 4 «Programming Demos».

2Send SCPI Commands via the PC Software

It is recommended that you control the power supply remotely by sending SCPI commands via the PC software Ultra Sigma provided by RIGOL.

SCPI Command Overview

SCPI (Standard Commands for Programmable Instruments) is a standardized instrument programming language that is built upon the standard IEEE 488.1 and IEEE 488.2 and conforms to various standards (such as the floating point operation rules in IEEE754 standard, ISO646 7-bit coded character for information interchange (equivalent to ASCII programming)). This section introduces the syntax, symbols, parameters and abbreviation rules of the SCPI commands.

Syntax

SCPI commands present a hierarchical tree structure and contain multiple subsystems, each subsystem consists of a root keyword and one or more sub-keywords. The command string usually starts with «:»; the keywords are separated by «:» and are followed by the parameter settings available. The command keywords and the first parameter are separated by a space. «?» is added at the end of the command string to indicate query.

For example, :SYSTem:COMMunicate:LAN:IPADdress <ip> :SYSTem:COMMunicate:LAN:IPADdress?

SYSTem is the root keyword of the command. COMMunicate, LAN and IPADdress are the second-level, third-level and forth-level keywords respectively. The command string starts with «:» which is also used to separate the multiple-level keywords. <ip> represents the parameters available for setting. The command

keywords :SYSTem:COMMunicate:LAN:IPADdress and parameter <ip> are separated by a space. «?» represents query.

«,» is generally used for separating multiple parameters contained in the same command, for example, :DELAY:PARAmeter <secnum>,{ON|OFF},<time>

Symbol Description

The following four symbols are not the content of SCPI commands and will not be sent with the commands. They are usually used to describe the parameters in the commands.

1Braces { }

Usually, multiple optional parameters are enclosed in the braces and one of the parameters must be selected when sending the command. For example, :DISPlay:MODE {NORMal|WAVE|DIAL}.

2Vertical Bar |

The vertical bar is used to separate multiple parameters and one of the parameters must be selected when sending the command. For example, :DISPlay:MODE {NORMal|WAVE|DIAL}.

3Square Brackets [ ]

The content (command keyword) enclosed in the square brackets can be omitted. When the parameter is omitted, the instrument will set the parameter to its default. For example, for

the :MEASure[:VOLTage][:DC]? command, sending any of the four commands below can achieve the same effect.

:MEASure?

:MEASure:DC?

:MEASure:VOLTage?

:MEASure:VOLTage:DC?

4Triangle Brackets < >

The parameter enclosed in the triangle brackets must be replaced by an effective value. For example, send the :ANALyzer:CURRTime <value> command in :ANALyzer:CURRTime 5 form.

Parameter Type

The parameters of the commands introduced in this manual contains 5 types: bool, integer, real number, discrete and ASCII string.

1Bool

The parameter could be «ON» (1) or «OFF» (0). For example, :RECorder[:STATe] {ON|OFF}.

2Integer

Unless otherwise noted, the parameter can be any integer within the effective value range. Note that do not set the parameter to a decimal; otherwise, errors will occur. For example, in

the :SYSTem:BRIGhtness <brightness> command, <brightness> can be any integer from 0 to 100.

3Real Number

Unless otherwise noted, the parameter can be any real number within the effective value range.

For example, for CH1 of DP831A, the ranges of <volt> and <curr> in the :APPLy CH1,<volt>,<curr> command are 0.000V to 8.400V and 0.0000A to 5.3000A respectively.

4Discrete

The parameter could only be one of the specified values or characters. For example, in the :ANALyzer:OBJect {V|C|P} command, the parameter can be V, C or P.

Chapter 1 Programming Overview

RIGOL

5ASCII String

The parameter should be the combinations of ASCII characters. For example, in the :MMEMory:STORe <file_name> command, <file_name> is the filename of the file to be saved and can include Chinese characters, English characters and numbers.

Besides, many commands contain the MINimum and MAXimum parameters which are used to set the parameter to its minimum or maximum value. For example, MINimum and MAXimum in

the :SYSTem:BRIGhtness {<brightness>|MINimum|MAXimum} command are used to set the brightness to the minimum or maximum.

Command Abbreviation

All the commands are case-insensitive and you can use any of them. If abbreviation is used, all the capital letters in the command must be written completely. For example, the :ANALyzer:ANALyze command can be abbreviated to :ANAL:ANAL.

SCPI Status Registers

All the SCPI instruments execute the status register operations in the same way. The status system records the various instrument states into three register sets: status byte register, standard event register and questionable status register sets. The status byte register records the advanced summary information reported by other register sets. The SCPI status systems of the DP800 series multi-channel models (take DP831A as an example) and single-channel model (take DP811A as an example) are as shown in Figure 1-2 and Figure 1-3 respectively.

Event Register

The event register is read-only and is used to report some states of the power supply defined internally. All the bits in the event register are latched and once an event bit is set, the later state (state of the event represented by this bit) changes will all be ignored. The event register bits will be cleared automatically when you send command to query the event register (such as the *ESR? or :STATus:QUEStionable[:EVENt]? command) or send the *CLS command to clear the register, but the reset command (*RST) will not clear the bits in the event register. When querying the event register, the query returns a decimal value corresponding to the sum of the binary weights of all the bits in the register.

Enable Register

The enable register is both readable and writable. It is used to define which status information will be reported to the next-level. The bits in the enable register will not be cleared when you send command to query the enable register or send the *CLS command to clear the register state (but the *CLS command can clear the bits in the event register). To enable the bits in the enable register, you need to write into the register a decimal value corresponding to the sum of the binary weights of the bits to be enabled in the register.

Multi-logic Output

This part is only applicable to multi-channel models. Take DP831A as an example. The 3-logic output of the power supply includes a channel questionable status register and three independent channel questionable status SUMMARY registers (corresponding to the logic outputs of the three channels respectively). The channel questionable status SUMMARY registers report the status of each channel to the channel questionable status register which then reports the channel status to the bit13 (ISUM bit) of the

Questionable Status Register

Questionable Status Register of Multi-channel Models

The SCPI status system of the multi-channel models is as shown in Figure 1-2. Wherein, the channel questionable status register indicates in which channel questionable event occurs. While for each specific logic output, the channel questionable status SUMMARY register is a pseudo-questionable status register.

The questionable status register provides information about the questionable status of the power supply. Bit4 (TEMPerature) reports the over-temperature state; bit11 (FAN) reports the fan failure state and bit13 (INSTrument summary) summaries the questionable output state of any of the three output channels.

You can send the :STATus:QUEStionable[:EVENt]? command to read the register. To use bit13, you must first enable the register the information of which you want to summarize using bit13. Send

the :STATus:QUEStionable:INSTrument:ENABle command to enable the channel questionable status register; then send the :STATus:QUEStionable:INSTrument:ISUMmary[<n>]:ENABle command to enable the corresponding channel questionable status SUMMARY register. The definitions of the bits in the questionable status register of the multi-channel models and the decimal values corresponding to their binary weights are as shown in Table 1-1.

Standard Event Register

The standard event register reports the following instrument events: power-on detection command syntax error, command execution error, self-test or calibration error, query error or operation complete. All these events or anyone of these events can be reported by the enable register to the bit5 (ESB, Event Summary Bit) of the status byte register. To set the enable register mask, you need to use the *ESE command to write a decimal value into the register. The definitions of the bits in the standard event register and the corresponding decimal values of their binary weights are as shown in Table 1-5.

Note: An error status (bit2, 3, 4 or 5 in the standard event register) records one or more errors in the power supply error queue and you can send the :SYSTem:ERRor? command to read the error queue.

:APPLy Command

The :APPLy command provides the most straightforward method to program the power supply over the remote interface. For the multi-channel models, you can select the specified channel and set the voltage and current in a single command; for the single-channel model, you can set the voltage and current in a single command. When the setting values are within the parameter ranges of the corresponding channel (multi-channel models) or range (single-channel model) of the specified model, the output voltage and current will change to the setting values immediately after executing this command. The voltage/current ranges and default values of each channel (multi-channel models) or range (single-channel model) of different models are as shown in the table below.

Explanation

For the multi-channel models, this command is used to select the specified

channel and set the voltage and current; for the single-channel model, this

command is used to set the voltage and current of the channel. This command combines the channel select command

(:INSTrument:NSELect, :INSTrument[:SELEct] or :INSTrument[:SELect], only applicable to the multi-channel models), voltage setting command ([:SOURce[<n>]]:VOLTage[:LEVel][:IMMediate][:AMPLitude]) and current setting command ([:SOURce[<n>]]:CURRent[:LEVel][:IMMediate][:AMPLitude]) functions.

In the query command, the parameter [CH1|CH2|CH3] is used to select the channel to be query. If it is ignored, the current channel will be query.

<volt> and <curr> are used to set the voltage and current of the specified channel respectively. If only one parameter is specified, the value is the voltage setting value by default; if both of them are omitted, the command will select the desired channel. The voltage/current ranges of each channel (range) of different models are as shown in Table 2-1.

You can use MINimum, MAXimum or DEF which denote setting the voltage or current of the specified channel (range) to the minimum, maximum or default instead of the specified voltage (<volt>) or current value (<curr>). The voltage/current ranges of each channel (range) of different models are as shown in Table 2-1.

[CURRent|VOLTage] is used to select to query the voltage or current of the specified channel. If they are both omitted, the system will query both the voltage and current of the specified channel.

In the query command, you can omit both of the parameters or only omit [CURRent|VOLTage]; but you cannot only omit [CH1|CH2|CH3].

Return Format The query returns a string.

The query returns the voltage or current setting value of the specified channel when [CH1|CH2|CH3] and [CURRent|VOLTage] are specified, for example, 5.000.

The query returns the channel (range) name, rated voltage/current value, voltage setting value and current setting value of the specified channel

(multi-channel models) or current range (single-channel model) when only

[CH1|CH2|CH3] is specified, for example, CH1:8V/5A,5.000,1.0000.

The query returns the voltage setting value and current setting value of the current channel (multi-channel models) or current range (single-channel model) when all the parameters are omitted, for example, 5.000,1.0000.

Example

:APPL CH1,5,1

The number of cycles refers to the number of times that the instrument performs delay output according to the preset state. Wherein, I represents infinite number of cycles; N represents finite number of cycles. The number of cycles is specified by <value> and when this parameter is omitted, the number of cycles is set to 1 by default.

The total number of groups of the delay output = the number of groups × the number of cycles; wherein, the number of groups is set by the :DELAY:GROUPs command.

The power supply will terminate the delayer function when the total number of groups of delays is finished or when the state that meets the «stop condition» (the :DELAY:STOP command) is detected. At this point, the state of the power supply depends on the setting of the :DELAY:ENDState command.

The query returns I or N,<value>, for example, N,100.

<secnum> is the group number of the delayer parameters to be set;

{ON|OFF} is the output state; <time> is the delay time.

<firnum> is the group number of the first group of delayer parameters to be queried; <timercount> is the total number of groups of delayer parameters to be queried. When <timercount> is omitted, the command queries a single group of delayer parameters by default.

Return Format The query returns a string starting with #. For example,

#90000000152,OFF,3;3,ON,1;; wherein, #9000000015 is the data block header; 2,OFF,3;3,ON,1; are the actual delayer parameters.

The data block header is used to describe the data stream length information and starts with #. For example, the number «9» in #9000000015 denotes that the 9-bit data (000000015) following it is used to denote the data stream length (15 bytes).

The format of each group of delayer parameters is «number,output state,delay time»; multiple groups of parameters are separated by»;». For example, 2,OFF,3;3,ON,1; denotes there are two groups of delayer parameters; the number of the first group of delayer parameters is 2, the output state is OFF and the delay time is 3s; the number of the second group of delayer parameters is 3, the output state is ON and the delay time is 1s.

Explanation

When FIX (fixed time) is selected, you can set the on delay (<value0>, namely

the duration when the state is «On») and off delay (<value1>, namely the

duration when the state is «Off»). Both the ranges of <value0>and <value1>

are from 1s to 99999s. When only one of the parameters is specified, the on

delay time will be set by default.

When INC (monotonic increase) or DEC (monotonic decline) is selected, the

duration is generated following the monotonic increase or monotonic decline

rule, namely the time is generated by increasing or declining at the step from

the time base value. You can set the time base value (<value0>) and step

(<value1>). The two fulfills the relation: time base value + number of output

groups*step value≤99999s. The actual range of <value0> is from 1s to

(99999snumber of output groups*step value); the actual range of <value1>

is from 1s to int{(99999s-time base value)/number of output groups}.When

only one of the parameters is specified, the time base value will be set by

default.

When <value0> and <value1> are both omitted, this command is used to

select the method used to generate time automatically.

Return Format

The query returns a string in «the method used to generate time

automatically,<value0>,<value1>» form, for example, INC,2,5.

Example

:DELAY:TIME:GEN INC,2,5

Explanation

<quoted string> is a string enclosed in double quotation marks, for example,

«RIGOL» (note that the content displayed on the instrument screen does not

contain the double quotation marks in the string). The string cannot exceeds 45 characters (comma, semicolon and period are treated as an independent character). If the string contains more than 45 characters, the command is invalid. The specified string will be truncated if it can not be displayed within a line (only the previous section will be displayed normally, and the rest section that needs to be displayed in a new line will not be displayed).

<coordinate X value> and <coordinate Y value> denotes the X axis (horizontal axis) and Y axis (vertical axis) coordinate values respectively (the coordinate values set are the coordinate values of the upper-left corner of the string on the screen). When only one parameter is specified, the horizontal axis value (<coordinate X value>) is set by default; when the two parameters are both omitted, the string is displayed at the default coordinate (5,110).

The ranges of <coordinate X value> and <coordinate Y value> are 0 to 320 and 0 to 240 respectively and the default coordinate is (5,110). If the specified X axis coordinate value is less than 2, the X axis coordinate value will be treated as 2; if it is greater than 315, it will be treated as 315. If the specified Y axis coordinate value is greater than 230, the Y axis coordinate value will be treated as 230.

Return Format

The query returns a string enclosed in double-quotation marks. The content

enclosed in the double quotation marks are the content actually displayed on the

screen (the double quotation marks are not part of the content currently displayed

on the screen), for example, «RIGOL».

Example

:DISP:TEXT «RIGOL»,25,35

/*Display the string RIGOL from (25,35)*/

:DISP:TEXT?

/*Query the string currently display on the screen

and the query returns «RIGOL»*/

Explanation

<enable value> is a decimal value corresponding to the sum of the binary

weights of the bits to be enabled in the enable register of the standard event

register. For the definitions of the bits in the standard event register and their corresponding decimal values, refer to Table 1-5.

For example, to enable bit2 (query error) and bit4 (execution error) in the enable register of the standard event register, set <enable value> to 20 (according to 22+24=20).

After the bits in the enable register of the standard event register are enabled,

the system reports the state of the corresponding bit to the status byte

register.

When <enable value> is set to 0, executing this command will clear the enable

register of the standard event register.

You can also send the *PSC (*PSC 1) command to clear the enable register of

the standard event register at the next power-on.

Return Format

The query returns a decimal value corresponding to the sum of the binary weights

Troubleshooting
The commonly encountered failures and their solutions are listed below. When you
encounter those problems, please solve them following the corresponding steps. If
the problem remains still, please contact RIGOL and provide your device
information (Utility SysInfo).
1.
The instrument can not start up.
(1) Check whether the power is correctly connected.
(2) Check whether the power switch at the front panel is really on.
(3) Remove the power cord and check whether the voltage selector is at the
proper scale, whether the specification of the fuse is correct and whether
the fuse is intact. If the fuse needs to be changed, refer to “To Replace the
Fuse”.
(4) If the problem remains, please contact RIGOL.
2.
The constant voltage output is abnormal.
(1) Check whether the maximum output power of the scale currently selected
fulfills the load requirement. If yes, go to the next step.
(2) Check whether the cable connecting the load and power supply is
short-circuited and in good contact.
(3) Check whether the load is normal.
(4) Check whether the current setting value of this scale is proper; if it is too
low, increase it properly.
(5) If the problem remains, please contact RIGOL.
