Rohde and Schwarz RT-ZC15B Current Probe, 50 MHz

The Rohde & Schwarz RT-ZC15B is a 50 MHz AC/DC current probe engineered for non-intrusive current measurement across dynamic analysis, troubleshooting, and laboratory applications. Operating across DC to 50 MHz bandwidth, the probe captures current waveforms without circuit interruption, enabling real-time monitoring of signal behavior. Direct oscilloscope powering via the R&S probe interface eliminates external supply requirements while the compact clamp design accommodates conductors up to 5 mm diameter.
