HF Antenna Analyzer
The AA-30.zero by RigExpert is a new DIY Antenna Analyzer component you
can use to build your own low cost arduino antenna analyzyer project, by integrating an arduino pcb, lcd display or even better a led display and the aa-30.zero.
.ZERO is even more powerful than the good old AA-30
It is a standard AA-30 analyzer but without enclosure, LCD display and keypad.
But .ZERO is even more powerful than the good old AA-30.
Why is that ?
Creating AA-30.ZERO we met the numerous wishes of radio amateurs and DIY-hobbyists to give them a measuring tool that can be easily integrated into their own projects.
Are .ZERO ready for use?
Yes, it has everything necessary on board, so user can connect .ZERO to the PC (through USB-to-RS232 adaptor) and perform all the usual set of laboratory measurements.
.ZERO perfectly works with our AntScope software.
Experienced user can pair .ZERO with the Arduino board making his own hardware/software project. Because .ZERO is compatible with Arduino standard.
Also we have already prepared examples of running .ZERO in the DIY projects.
Want to make your own automatic antenna tuner ? Use .ZERO!
Want to perform RF-circuits or antenna analysis remotely ? Pair .ZERO with the ESP8266 Wi-Fi SoM and do it!
Want to tune your antenna with driven elements sharply ? Use .ZERO to fine tuning.
Price & Power
It is not possible to find such an accurate and powerful analyzer at this price!
The dreams of radio amateurs will come true with this cheap and reliable device!
The AA-30.ZERO is intended for users who require flexibility, low-cost, and small size.
It comes without on-board USB or pin headers to keep the cost down.
It’s a best choice for a measuring core you want to leave embedded in a project.
Please note that the .ZERO operates at 5V (like most Arduino or Arduino compatible boards).
Be sure to provide the correct power and use components/adaptors whose operating voltage matches .ZERO.
Connecting .ZERO to the PC
The .ZERO comes without built-in USB circuitry, so an off-board USB-to-TTL serial convertor must be used to communicate with the .ZERO.
.ZERO communicates with external devices throug UART interface.
For these purposes two UART interfaces are provided: UART1 (pins 0/TX1 and 2/RX1) and UART2 (pins 4/TX2 and 7/RX2).
By default .ZERO uses UART2 interface.
To make our first project we could get, for example, the SparkFun USB UART Serial Breakout.
