New firmware for AA-30 ZERO
We have released a new firmware update for the AA-30 ZERO analyzer (version 2.0)
In this version, we added the ability to measure at a single frequency.
You need to make measure at a frequency of 14100 kHz.
To do this, send the following commands to the analyzer:
The ver command will return the name and version of the analyzer firmware:
The value of the measured frequency in Hz. If successful, the analyzer returns OK.
Command to set the scan range width. Since we need to measure at one frequency, set the value to 0. The analyzer will return OK if successful.
The command sets the number of measurement steps. Since it takes n+1 points to plot the graph, for a single measurement at one frequency, we send the analyzer 0. If successful, the analyzer will return the result in the form of frequency, resistance value, reactance value (taking into account the sign) and OK.
If an error occurs, the analyzer returns an ERROR.
You can update the analyzer firmware using the FlashTool utility. The version for Windows and MacOS can be downloaded HERE.
We strongly recommend updating the analyzer firmware using a USB-to-UART adapter. Don’t use Arduino.
Good news! Our programmers have developed a special library for Arduino which simplifies the work with the AA-30 ZERO. Soon we will publish a detailed article. Follow the news on our website and group on Facebook.

Hello. Congratulation for this nice project ! It gives RigExpert's quality for a moderate price ! I just assembled mine and it works great ! Did someone try to upgrade the embedded Arduino software with more possibilities, as displaying complex impedance with the swr so it will be possible to estimate if the DUT is capacitive or inductive ? I have a question about the frequency range of the AA-30 Zero : it is written that the range is 100 kHz to 170 mHz, but the software is limited to 30 mHz... Can the AA-30 Zero be used up to 170 mHz (for 2 meter band) ? 73 from Fabrice, F5HCC.
