Default Re: Advance E2 Signal Generator repair

Thanks all.
I've done some further checking- the connector does appear to be a generic TV aerial connector and it appears that a poor connection was responsible for the early errors. I've re-checked across all bands, and it looks like C to F are good for both full and ATTEN connections- see summary table for full results. B is lower amplitude and A is not working (unless the scope it not capable of operating for these freqs).
The main issue now is modulation. Flicking the Mod switch to INT does not appear to have any AF modulation effect that I can see- just reduces the amplitude slightly. I've attached some images that I hope will help to show what is happening.
