I think to know the answer, but I'd like to know yours about a simple question.
I've tried my Tek 2465B with a fast (<2ns) 820Hz square wave (from a toy Tek used to demonstrate the superiority (!?) of digital vs. analog scopes).
Anyway, with 1ns/div sweeping time (and the X10 multiplier, of course) with a normal sunny daylight the trace is almost invisible.
Is this normal?
I suppose that the high speed and the low refresh rate are the "trick", but I would like to be sure...
This could be a 2467B task...
Thank you for your opinions
