The Rohde & Schwarz RT-ZZ80 is a passive broadband transmission line probe designed for high-frequency signal acquisition on 50 Ω measurement systems. With 8 GHz bandwidth and a 10:1 attenuation factor, it delivers precision measurements across demanding RF and mixed-signal applications while maintaining minimal loading effects on the circuit under test. The probe’s 0.3 pF input capacitance and 500 Ω input impedance preserve signal integrity on low-impedance transmission lines. It handles input signals up to 20 V (RMS) with ±1% attenuation accuracy and 60 ps rise time, making it suitable for capturing high-speed transients without distortion.
