Just be careful, the output of the NanoVNA is a square wave, thus has a lot of harmonic energy. I’ve always liked how you test devices beyond what their intended use is. You don’t have to set start and stop frequency to the same to get CW, you can just select “CW frequency” below that to get CW mode Using a Nano VNA as an RF signal generatorĪ few things to do with the versatile Nano VNA. Here are some videos on using NanoVNA as signal generator: NOTE: Be very careful not to overload the output or feed a voltage/signal to it, else the NanoVNA would be damaged! Just set the centre frequency of the stimulus at the value you need and a span of 0 Hz. If you are in a hurry and need a quick & square wave signal between 50 kHz and 300 MHz the NanoVNA can come to the rescue. NanoVNA vector signal analyzer can be used also as an RF signal generator.
