[volt-nuts] I have a few parts units here 4808 and I think a 4700 also which plugs?

I have a 4708 on fleabay now which needs a front panel. Or at least a display, since the left side display (frequency) is broken. If I could get it working, I could use it for my 3457 work. Willy ___ volt-nuts mailing list -- volt-nuts@febo.com

Hi Dave; In a more detailed response to your question, i do not know a great deal about the 3457A but in recent years I have had multiple 3458A's on my bench at a time and I have found on those instruments the AD drift can very often be greater then the reference drift. A-Cal will correct the

I've got two different, but not totally unrelated questions. 1) Does anyone know what is the power consumption of the 3458A reference board? I was thinking of getting one, boxing it up with a battery, that allowed it to keep running without mains power. I would like to know the energy storage the
