Re: HP 8662A - alternative attenuator configurations, 8663A Last Rev Mnl
There is a rather simple solution: Scan only the oversized pages. Typically, the theory sections only change slightly over the life of an instrument. You could scan some of the sections referring to

Re: HP 8662A - alternative attenuator configurations, 8663A Last Rev Mnl
I'm sure that these are rare. I was in a place 10 years ago that I was able to purchase a number of the end-of-life manuals with all the updates, expensive but I thought it worth it. I couldn't do it

Re: HP 8970B battery backup troubleshooting
Just looking at the schematic, I wonder about a few things: did you measure the current through (or voltage drop across) R23? This would be both in power on and power off. I'm assuming (as a fault

Hi Matt, I don't know the 8970B, so this is just my general thoughts. Just to verify that I fully understand. When you measured the lover voltage of the replaced battery, this was measured at the

WTB (wish to buy) N2757A GPIB interface module for a 54622D MSO
Hello, I wanted to standardize on GPIB for my HP/Agilent/Keysight instrument collection and realize the MSO didn't come with GPIB. I think per the manual an old N2757A is probably useful to do that.
