Jay,
IIRC, that analog error is an analog channel triggering error. I believe
that all of the extended self-test error codes are spelled out in the
service manual.
As a quick check, you can try triggering the scope section from all
three channels, and I think you'll find at least one (Channel 2?) won't
trigger the scope, but it will still digitize a waveform. For most
purposes, the logic analyzer will be fine, but if I were you, I'd take
the company up on the offer to replace it.
If the replacement 1631D passes all of the extended self-tests, you can
be 99.9% sure that it has no internal problems, since these tests are
very extensive.
Hope this helps!

Anyone familiar with an HP 1631D logic analyzer/scope?
I just got one used (with pods and grabbers)... no manual yet, so I'm
shooting in the dark on this.
There's a selftest dip switch on the back. If I set it and power up, the
screen says...
------------
Ram OK
Rom OK
Acquisition OK
Analog Error:
21 00 00
Reset back panel switch to........

I talked to the company I bought it from - they're not familiar with the
unit but said they'd gladly send me a different one if mine was bad so I'm
not worried about that. However, I'm wondering if anyone can tell me if this
really indicates a problem or does the selftest expect a probe to be
connected or something (nothing is connected to it now). Any ideas?
On a different note... HP quotes the manual for this unit at $72.00USD.
Would anyone have one I can borrow and copy for less?
Please reply to the list or to west(a)tseinc.com, not this address.
Thanks!
