Hi all,
I have looked through the archives and found that the 5370B has a better
front end and dacs and consolidated the ram and mpu onto one card.
However, can someone tell me how much better? these changes make the
5370B? What effect upon measurements does the new front end have over
that

The input changes affected the /1 input dynamic and operating ranges.

Last night I got it back out of storage and powered it up. Initially,
Hi Stan,
It gets like a broken record, but the first place I always go when a
formerly working piece of test equipment stops working is the power
supply.
Check the power supply voltages for both value, and ripple.
Then check all of the electrolytic capacitors for ESR. It only takes

I'd recommend putting it in open loop and removing top and bottom covers.
Place on it's left side and hook a scope to the tp1 test point on the

I recently purchased a 5065A that did not work but was 'fixed' by unseating
all the PC cards and reseating them. I was quite dirty to start with
