Sweep output debugging [1 Attachment]
It seems to that that you nailed it. Congratulations.
Since I already have a PHSNA I plan to use one "Experimental board" for making a HF signal generator. (I have several but making this one could be fun and instructive). I will pay due attention to the transformer issue.
I will use a Type II DDS, an Arduino Nano and a 31 dB solid state variable attenuator module (18 € from China). I will add a couple of relay controlled 30 dB fixed attenuators for increasing the range and an ALC circuit for compensating the DDS slope and also to perform AM modulation. I also plan to add a LCD and an encoder and, of course, USB computer control.
