Rohde & Schwarz RT-ZZ80 Oscilloscope Probe, Passive Type, 8GHz, 10:1, BNC, SMA adapter Connector

The Rohde & Schwarz RT-ZZ80 passive broadband probe is an economical, yet powerful alternative to active probes for measuring high-speed signals on low impedance lines. Its input impedance is low but remains practically constant over the entire frequency range.

Feature an extremely low input capacitance and particularly low noise
Provides an attenuation factor of 10:1 at an input impedance of 500 O || 0.3 pF
