描述

RigExpert AA-55 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 60 kHz to 55 MHz.

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

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-55 ZOOM – How it works?

Structure diagram

The structure diagram of RigExpert AA-55 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.

Does AA-55 ZOOM have BlueTooth or not?
Rigexpert used to put BlueTooth inside AA-55 ZOOM units but the modules inside became obsolete during the post-Covid semiconductor shortages. So RigExpert stopped installing BlueTooth inside AA-55 ZOOM. It is not possible to buy any new units with BlueTooth from RigExpert. However we were able to obtain BlueTooth modules and we are now shipping BlueTooth models exclusively. If you need BlueTooth you can still buy models with BlueTooth from PCS Electronics.
