Greetings all,
I recently got a probe back from repair. Reinstalled it, went to tune it
(ssNMR, manual tuning) and only got noise on all channels. I checked the
probe with a network analyzer, it tunes; test the system out by attaching a
different probe.. Still noise. I have 5 mV AC at the cable and have a
standing wave signal (thank you fancy oscilloscope). I can even get spectra
when tuning before hand then reattaching the console to the probe and pulsing.
I was wondering if anyone else has seen anything like this and can direct me
to what may be causing my problems.
