Manufacturer: RigExpert Ukraine
Warranty: 2 years
RigExpert AA-1000 is a powerful antenna analyzer designed for testing, checking, tuning or repairing antennas and antenna feedlines.
Graphical SWR (Standing Wave Ratio) and impedance, as well as Smith/polar chart displays are key features of this analyzer which significantly reduce the time required to adjust an antenna.
Easy-to-use measurement modes, as well as additional features such as connection to a personal computer make RigExpert AA-1000 attractive for professionals and hobbyists.
The following tasks are easily accomplished by using RigExpert AA-1000:

The structure diagram of the RigExpert AA-1000 Antenna Analyzer is located below:
The “brain” of the analyzer is Atmel 8-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 rectangular signals with LVDS levels. Resistive bridge 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 2 kHz. A variable attenuator is used to maintain the audio signal level in the desired range. This signal is then filtered and fed through the 16-bit ADC to the microcontroller. There is a simple relationship between the measurement frequency, DDS frequencies and attenuator division ratio:
|Subband||Measurement frequency||DDS1 frequency||DDS2 frequency||Harmonic number||Attenuator ratio|
|1||0.1 … 200 MHz||0.1 … 200 MHz||DDS1 + 2 kHz||1||/25|
|2||200 … 600 MHz||67 … 200 MHz||DDS1 + 667 Hz||3||/3|
|3||600 … 1000 MHz||120 … 200 MHz||DDS1 + 400 Hz||5||/1|
|4||1000 … 1400 MHz||142 … 200 MHz||DDS1 + 286 Hz||7||*2|
The 320×240 colour TFT display and the 6×3 keys keypad are connected directly to the CPU. The analyzer is equipped with 128K of external Flash memory to store measurement results, as well as with 32K of the fast external FRAM. The USB interface chip allows connecting the analyzer to the PC.
This is a diagram of the resistive bridge and its connection to the detector:
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.

Make sure the latest firmware is uploaded to the analyzer. See the Downloads section.
* The AntScope software is able to plot graphs in Time Domain Reflectometer (TDR) mode when AA-30/AA-54/AA-170 is connected to the computer. Since the resolution of the TDR graph is proportional to the maximum operating frequency of an analyzer, much better results are obtained by using AA-230 ZOOM, AA-600, AA-1000 or AA-1400.
