As we mentioned in our previous update, we have been working on analog modulations. We’ve finally added FM functionality to ERASynth.
When it comes to microwave synthesizers, there are several ways of implementing analog modulation functions. These are very nicely outlined in the article "Implementing Modulation Functions in Microwave Frequency Synthesizers" by Chenakin.
During the past week, Erkin has explored different methods of FM signal generation. Please watch the following video for a quick demo. We also show the "Diagnostics" feature of ERASynth in the video.
