I have just bought a Tektronics 2430 scope that is failing the 7000, 8000,
and 9000 series of tests. When I go into the subtests, it is almost
exclusively only failing on channel 2. If I exit the menu functions,
channel 1 seems to operate okay, but I get no trace for channel 2. The
Operations manual seems to say that this condition may be caused by a
calibration failure, and the scope certainly won't complete a self cal. Is
this likely to be something that can be corrected by calibration, or does it
sound like a hardware failure? I know this is a bit of an open question,
but any help would be appreciated. I opened the scope up and it looks like
a library shelf of closely packed boards. I read a horror story somewhere
of someone who inadvertently disconnected the NVRAM battery, and lost all of
his calibration settings. Is this something that is likely to happen if I
start pulling boards out?
Once again; any help would be appreciated.
