What is the best method/procedure to measure DC voltages higher than +-24V with the n7020a?
I would be looking at measuring -32V.
A resistive voltage divider should work.
- The noise in the system will be higher, relative to the signal.
- The probe is high-impedance, so it will have minimal effect on the divider circuit.
- You don't say what BW you need, but you should use high-frequency resistors.
P.S. Call the Technical Call Center....
I doubt that this is possible. This probe depends on a clean offset voltage provided by the scope, and that offset is limited to +/- 24V. There was some discussion of creating a different probe with up to 48V of offset, but that may never happen.
That said, this is a question that should be addressed by your local Technical Call Center. Go to www.keysight.com/find/contactus for your local contact information.

Thank you for the reply. My question relates to using attenuation before using the probe. ie. like voltage divider.
