Rohde & Schwarz RT-ZD Oscilloscope Probe, Differential Type, 3GHz, 10:1, BNC Connector

The Rohde & Schwarz RT-ZD 3GHz differential broadband probes has a flat frequency response and a high input impedance with low input capacitance permit precise measurements on differential signals while keeping the loading on the DUT low.

High common mode rejection
Low loading at DC and high frequencies
