Interesting note, I was using the BNC connections. I
also noted that I had some ground noise, and at really
low output levels, sometimes the desired signal would
be swamped by line current. But yes, I believe I
sorta know what you're talking bout.
I cleared some of it up by grounding the op-amp to the
frame with the signal gen in it.
An interesting note, I've had this problem with tubed
rf alignment equipment. I solved it by swapping the
ground and signal test points!
I later read from a Tek measurement something or
another, that it was just a kludge fix as floating the
scope : (
Thanks. I hope to actually stop playing and doing
more directed studying.
Thanks.
