I have just got a Gould 465 DSO (same as 420 & 450 but 100MHz
bandwidth).
With the input grounded the trace is never dead straight (as with an
analogue scope) but exhibits a very, very tiny amount of vertical
noise. It doesn't alter with channel sensitivity and is the same on
both channels, so I'm guessing it's due to ADC error. Everything else
about the scope works perfectly.
It's livable with but if anyone can tell me whether this is normal
behaviour for these scopes (or other DSOs in general) I'd appreciate
it.
