Re: Threads for screws on 8656 Siggen
Hi all
The threads you are looking for are M3.5, this is a little used thread except in the UK where it is used by electricians to hold switch face plates in place, it is actually very close to 4BA

Re: hp8970a recallibration attenuator help
Hello Roberto,
Special Function 33 is for calibrating the IF attenuators. Just connect a 15 dB ENR noise source and execute SF 33. Temperature entering not necessary.

From these choices, it sounds like a stereo microscope on a boom would be
ideal. I do tend to work on all sorts of positions and oftentimes spill
