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 the user can connect .ZERO to the PC (through USB-to-RS232 adaptor) and perform all the usual sets of laboratory measurements. .ZERO perfectly works with our AntScope software. Want to DIY ? An experienced user can pair .ZERO with the Arduino board, making his own hardware/software project. Because .ZERO is compatible with Arduino standards. 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!
