  Introduction Thank you for purchasing a RigExpert AA-35 ZOOM Antenna and Cable Analyzer! We did our best to make it powerful yet easy to use. The analyzer is designed for measuring SWR (standing wave ratio), return loss, cable loss, as well as other parameters of cable and antenna systems in the range of 60 kHz to 35 MHz.

• Page 6: Multifunctional Keys

  Multifunctional keys Most keys on the analyzer’s keypad perform several functions. For instance, numbers (1) are used to enter frequency and other numerical parameters. Main functions (2) provide quick access to most common tasks. Alternative functions (3) are executed if the user holds the (Functional) key.

  Applications Antennas Checking the antenna It is a good idea to check an antenna before connecting it to the receiving or transmitting equipment. The SWR chart mode is good for this purpose. The picture on the left shows the SWR chart of a HF antenna.

  • In the open-circuited case, resonant frequencies correspond to (left to right) 1/4, 3/4, 5/4, etc. of the wavelength in this cable; • For the short-circuited cable, these points are located at 1/2, 1, 3/2, etc. of the wavelength. RigExpert AA-35 ZOOM…

  Cable length measurement Resonant frequencies of a cable depend on its length as well as on the velocity factor. A velocity factor is a parameter which characterizes the slowdown of the speed of the wave in the cable compared to vacuum. The speed of wave (or light) in vacuum is known as the electromagnetic constant : c =299,792,458 meters (or 983,571,056 feet) per second.

  (in 616,640,000 feet per second Hz). 3. Finally, find the velocity factor . 188,000,000 / 299,792,458 = 0.63 Just divide the above speed by the — or — electromagnetic constant. 616,640,000 / 983,571,056 = 0.63 RigExpert AA-35 ZOOM…

  Cable fault location To locate the position of a probable fault in a cable, just use the same method as when measuring its length. Watch the behavior of the reactive component (X) near the zero frequency: ∞ • If the value of X is moving from – to 0, the cable is open-circuited: ∞…

  4. Cut little pieces (1/10 to 1/5 of the 11 cm (0.36 ft) were cut off. margin) from the far end of the cable until the X value falls to zero (or changes its sign). Do not forget to restore the open-circuit, if needed. RigExpert AA-35 ZOOM…

  Measuring the characteristic impedance The characteristic impedance is one of the main parameters of any coaxial cable. Usually, its value is printed on the cable by the manufacturer. However, in certain cases the exact value of the characteristic impedance is unknown or is in question. To measure the characteristic impedance of a cable, 1.

  The analyzer can measure capacitance from a few pF to about 0.1 μF as well as inductance from a few nH to about 100 μH. Since measuring of capacitance and inductance is not a main purpose of RigExpert analyzers, the user will have to gain some experience in such measurements.

  Unknown inductor Transformers RigExpert analyzers can also be used for checking RF transformers. Connect a 50 Ohm resistor to the secondary coil (for 1:1 transformers) and use SWR chart, R,X chart or Smith chart modes to check the frequency response of the transformer. Similarly, use resistors with other values for non-1:1 transformers.

  Traps A trap is usually a resonant L-C network used in multi-band antennas. By using a simple one-turn wire coil, a resonant frequency of a trap may be measured. Example: A coaxial trap constructed of 5 turns of TV cable (coil diameter is 6 cm) was measured.
