Last summer I
picked up a Tek 2230, a 100 MHz two-channel
digital storage oscilloscope.
I think I'd like to check it checked out by a repair
service to confirm whether all its functions are working or not.
Why? I am guessing you will be out $50 to $100, and thats assuming its fine
and needs no "adjustment".
I would just use it, wouldn't most problems be fairly obvious?
This is a good point, especially with a DSO. Except for the analog
stuff in the very front-end...isolation, maybe a preamp, and some
attenuator hardware...the only things that I can think of in most
simpler DSOs that might require adjustment would be the time base and
the sweep alignment & linearity stuff. Tek DSOs are pretty solid; I'd
bet that, if it's basically functional, it's in good shape.
