How good is your scope? (problem with capturing offset signals)

[...]

This would probably be the point where I couldn't wait any longer, crack open the probe enclosures, and get into trouble :-)

There'd have to be some sort of semiconductor involved here. Maybe some sort of limiter circuit?

7A13 with attenuator set to 1mV per division recovers to within 2mV in 1us, and 1mV in 100us after a pulse of +/- 10V. (Per published spec)

And it does, too. Better, in fact, with the five I have around the lab, and have personally calibrated. It's part of the performance check procedure.

Effective offset range of 10,000 divisions.

I must try the same test with a 7A26. There's one that needs my attention for unequal trigger delay between channels. Probably another of those goddamn made-in-Tucson trimmer capacitors again. I'll try when I fix it.
