Ok, we are making good progress.
I found another issue, this time with AM/FM, mostly FM.
AM modulation appears to work, however the "CW Frequency" should be "Mod Frequency" or "Modulation Frequency". So really just a typographic issue.
FM on the other hand has some serious issues. It would appear the Parameter frequency is being ignored to set the carrier frequency and instead "CW Frequency" is being used to set the Carrier frequency. This is fine except I can't get the modulation frequency to set. Perhaps the "Frequency" and "CW Frequency" fields are flipped around. In any event FM modulation isn't working at all well for me. The DDS functions are getting very close to fully working.
Edit:
I confirmed that the two frequency fields appear flipped, also entering 10000000 (10Mhz) into the CW Frequency field results in a carrier frequency of 5 Mhz (1/2). I can post more details if needed. The data is being pulled from the wrong field for setting the carrier frequency as well as the modulation frequency, this is only a problem for FM, AM works well.
Thanks
