The Rohde & Schwarz URY-Z4 is an RF insertion unit that enables direct signal measurement and insertion in 50 Ω circuits across the VHF, UHF, and microwave spectrum. Operating from 100 kHz to 2 GHz, it measures voltage, power, and RF level with minimal insertion loss, making it ideal for in-circuit testing without disrupting system performance. The unit handles up to 100 V and 200 W, with measurement resolution extending to 2 mV and 100 nW respectively. N-type connectors ensure secure RF coupling in demanding test environments.
