I might aquire a faulty HP54201D scope.

It appears to show the following errors:

ST1:
Failed Auto Scale test

ST 2:
The period measurement must be 500 ns ±20 ns to pass.
FAILED Chan 1 test RR [03] == Period measurement failu no vailid
signal present.
FAILED Chan 2 test RR [01] == Period measurement failu the period
measurement was too low.

Sometimes it appears that ch2 behaves the same as ch1.

Cal 3,4,5 and 6 fails as well.

Anyone that is familiar whith this scope

Question is, is it repairable or is it a no-go?




With best regards

Do any of the failures include a bad NVRAM?

I bought a 54501A that was failing an assortment of self-tests and
replaced the NVRAM module (I'm sure the battery was gone after 20
years), and it seems to work perfectly now.
