Help: HP4274A process amplifier DC offset adjustment
« on: June 23, 2015, 01:04:19 pm »
I recently acquired a HP4274A and I'm having some trouble with one of the adjustment procedures: section 5-20 process amplifier DC offset adjustment. I downloaded the service manual from Keysight's website but unfortunately the scope images are unreadable and the text is not very clear (probably translated from Japanese). Does anyone know/have a better source for this adjustment procedure? Maybe a color scan from an original manual?
There are small lies, big lies and then there is what is on the screen of your oscilloscope.
