The SINAD picture above was receiving a signal from my Hp sig/gen through the radio under test.
Didn't need to use the reference sig from the SINAD program.

Those E200D B&K Precision sig/gen can be stable and have relatively low noise output. Owned one of them for a total of 2 days before I got my money back; it had a known issue with Q-9 and just didn't want to deal with it. It also uses a 400hz audio signal for the reference freq; not 1khz! But it can be modified to do 1khz. That may well be your problem. If so; then you may need to use the SINAD program's 1khz generator into your B&K - or use the 1khz mod below - to get you on the right road.

Be SURE to test the output FREQ (eg. 27.185mHz) of your gen to be sure that it is stable to +/-200hz on AM.

If there is a problem with yours - DWB, then check out all of these links:
