Looks cool; we'll try one.



The old Tek plugin scopes had nice diffamp modules, but no more.



This is nice, fully isolated, but expensive:

OK will you post pics? (What's the input protection?)

Max freq is only 1MHz? that's not much, is it?

OK for lots of low-level things.

Sure, a gain of 1k at 1MHz would be nice.

I mostly live at audio freqs. (or lower.)

Looks interesting. Wonder how it does for overdrive recovery (something the old Tek diff amps excelled at)? Input noise specs? The web page doesn't speak to these.

Click on the manuals button and the product overview flyer says input noise at 1 MHz is 5 nV/rt Hz. Nothing about overdrive recovery.
