描述

RigExpert AA-230 ZOOM

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 100 kHz to 230 MHz.

A built-in ZOOM capability makes graphical measurements especially effective.

An integrated Time Domain Reflectometer mode can be used to locate a fault within the feedline system.

The following tasks are easily accomplished by using this analyzer:

  • Rapid check-out of an antenna
  • Tuning an antenna to resonance
  • Comparing characteristics of an antenna before and after specific event (rain, hurricane, etc.)
  • Making coaxial stubs or measuring their parameters
  • Cable testing and fault location, measuring cable loss and characteristic impedance
  • Measuring capacitance or inductance of reactive loads

RigExpert AA-230 ZOOM – How it works?

Structure diagram

The structure diagram of RigExpert AA-230 ZOOM is located below:

The “brain” of the analyzer is STM 32-bit RISC microcontroller. It controls a AD9958 DDS chip running at 500 MHz and generating two sinusoidal signals. Both signals are low-pass filtered and then put through pulse shapers, producing two square signals with LVDS levels. Resistive brigde was chosen to measure parameters of a load because of its simplicity and good frequency response. The switch commutates two outputs of the bridge. After the switch, the signal is mixed with the second channel output to produce audio frequency of 1.5 kHz.This signal is then filtered and fed through the 16-bit ADC to the microcontroller. The 290×220 color TFT display and the 6×3 keys keypad are connected directly to the CPU. The analyzer is equipped with 4 Mbytes of external Flash memory to store measurement results. The USB interface chip allows connecting the analyzer to the PC.

Close look at the bridge

This is a diagram of the resistive bridge and its connection to the mixer:

The switch which is controlled by the CPU feeds the signal from the certain side of the bridge to the mixer chip. When the load is totally active and its resistance is 50 Ω, the bridge is balanced and the switch outputs the same signal in both positions. This eliminates the need of calibration of the analyzer, also giving very good precision near SWR=1.

RigExpert AA-230 ZOOM – Frequently asked questions

Q: The output RF level at the antenna connector of the AA-230 ZOOM is -10 dBm, which is quite low compared to many other instruments. Does it mean the analyzer will not operate properly with long cables?

A: No, the AA-230 ZOOM will work fine with long (hundreds of meters) cables. The analyzer has a very sensitive, narrow band input, so -10 dBm is much enough for accurate measurements, even after loosing a few decibels in a long cable.

Q: The specs say the AA-230 ZOOM has a square wave output, which means there are several frequency components (harmonics) in such a signal. Then, how the SWR and other parameters of my antenna are measured at a specific, single frequency?

A: Please look at the structure diagram of the analyzer. The instrument filters out all unnecessary frequency components, thanks to the very narrow band (several hundred Hz) filter.

Q: Is the AA-230 ZOOM sensitive to nearby repeaters or broadcast transmitters?

A: No, unless a high-power transmitter is operating closely at the same frequency you are trying to use the analyzer at.

Q: Can I charge Ni-MH batteries inside the analyzer?

A: No, please remove batteries from the analyzer and use a separate charger.

Q: Can I use Lithium-Ion batteries instead of alkaline or Ni-MH ones?

A: Most likely, you will burn the analyzer. Lithium-Ion batteries have an output voltage of about 3.7 V each: compare to 1.2 V  for Ni-MH and 1.5 V for alkaline ones.
