I am a complete newbie on this forum and this is my first post. I hope I am doing it correctly.
I have what seems to be a very rare Racal-Dana 3101 10 KHz - 1300 MHz synthesized signal generator of 1988 vintage. I have the original Racal operator's handbook. It shows 'error 80', which means main oscillator loop is out of lock. The problem comes with getting at the right pot or trimmer to tweak.
Has anyone ever taken the covers off one of these heavy pieces of kit and been able to open anything ? Underneath there is a large metal plate apparently mounting all the boards, but I cannot move this after removing its small crosshead screws.
I would welcome with any advice on this magnificent sig gen.
Thank you.
