Finally got around to testing the v3 on my SA after recalibration. I am pleased to see that the harmonics were within spec of the FCC Part 97 Section D emission standards for all bands (-43dB or lower). My SA can only show 10MHZ bandwidth at a time so I also checked subharmonics and there are some inconsistencies that I need to re-verify.
This was done after performing a recalibration cycle on all bands. Next test will be performed with my SA, AA, RF Tap, and scope to check subharmonics and modulation purity. The sBitx is very handy to include 2Tone mode to check IMD without a requirement for external signal generators (I have a couple if needed).
I may as well test the receiver side as well.
