2 questions on HP 5371A/5372A
-
what or where is the gate time for the 5371A/5372A -
how do I turn that CRT off while making very l o n g GPIB measurements?
Geez, you'd think nobody had one of these things.
-
The 5372A doesn't use anything so common as "gate time". No, it
uses "interval sampling" instead. Take a look in the Operating Manual
on page 1-23 "Time Interval Measurement with Interval Sampling Arming".
Clear as mud, isn't it? But that's what you want. The maximum gate
time is 8 seconds. The same applies to frequency measurements. -
The closest thing they've got to a screensaver is the "Display
Blank" which really isn't anything close to a screensaver. :-( It's
described on page 12-6.

Ah more people should take the leap, the broke ones are cheap and are moistly easy to fix and you have the almighty HP service manuals to guide you through the toughest of faults.
Isn't it great how they even deal with handling multiple faults in the manual, although the great techs such as you Ed, break it up into blocks without thinking about it.
Fortunately, the parts aren't too hard to come across, although you might be stretching it to get some of those hybrids...
The 5372A will never take the place of the 5370B, so I guess the poor 5372A hasn't got "time-Nut" stamped on it..
But I was playing around with mine and I have to say it's fine for quick measurements.
Well, Here's to R.T.F.M. (the fine one that is ;) Cheers,

The one thing you could do is to enable the fast port and hack up a
board that consumes the data and produces a long continuous stream of
data for tools like TimeLab etc.
When doing such long-time-logging, the 200 ps resolution isn't all that bad.

Hi
The lack of long tau analysis is what keeps the 5371 and 5372 from becoming staple items with TImeNuts.
