> Why, you use your 8082A! I got one for a steal a couple of years ago on
I've been looking for a year now, and I haven't found any 8082A's below $400.
Well, there were a couple, but they were a real mess.
5370A's, which are equivalent to the 5370B in all respects have been
going for less than $100 on the 'bay.
[The only significant difference I have been able to find between the "A" and
"B" is the CPU card and memory have been consolidated. Specification wise, they
are identical in all respects. HPIB wise they are also identical. As are they
in measurement rate, and HPIB throughput.]

From reading the alignment procedure, the 8082A barely meets the needs.
I haven't found anything else that comes close in one package.

141T systems are available for much less than the cost of an 8082A, and
are much more useful generally.
