Is there ever a reason for the 16530A/16531A board test to fail a self

I would think this should not happen. Maybe if it had something to
do with the two boards not being connected up correctly. Are there
any interconnecting cables between the boards?
One, and it's in there already, connecting the two boards. I suspect
that's the internal trigger and acquisition signals from the sweep to
the scope board.
I don't know anything
about how these two boards work together, but I can imagine you might
get some kind of error if they are supposed to connect together
internally, but aren't properly connected. Or, perhaps there's a
jumper that needs to be set. So, it may be the memory is bad like
you suspect.
Unless I missed one, there are no jumpers at all on the boards.
I checked and the only manual I have is also just the programmer's manual.
Time to look at "buy it now" I think, and failing much else, talk to
the seller.
I can't figure out why there would be a problem as well.
Also, the trace is distorted in at least one area, so I'd suspect that
the diagnostics are right. It's only about 10 samples, though, but
still....
