Thanks Steve. I was wondering how your probe looked.
When I have my analog hat on, I've used active probes many times for low frequency design because impedance is high down there, while capacitance is low. I was attracted to the 2796A as it gives a decent input and offset range, plus high impedance. And it also gets the scope ready for the future
Now I'm thinking about going back to the Tek probes. They are cheap and plentiful compared to Agilent stuff. My P6245 probe heads are half the size of Agilent's.
I do like the 1153A however. The one I got was complete with attenuator heads, etc. I have a Linear Tech LTM8049 eval module which I milled down to the core circuit. It will fit nicely into the 1153A AutoProbe box and give the dual 5v to 6v boosts it needs.
