Re: Trying to understand the 453 calibrator
There is a bit of a clue in that the calibration loop on the right-hand side is marked with an arrow pointing left and the words "5mA" followed by a square-wave. The calibration BNC on the front panel is marked "1 kHz". This should lead one to think that the BNC on the front-panel is for Time/Div calibration and the loop on the right side is for Current/Div calibration. I will have to look at how the "1kHz" is generated to see if it really is accurate (most of these are not that accurate).toggle quoted messageShow quoted text

Harvey (and all),
Yeah, my loop is directly grounded, so I will get my calibration voltage signal from the BNC on the front panel. Works fine.
Glad to learn aboutthis. Thanks, all.
