An isolated probing system, the R&S RT-ZISO measures fast switching signals in environments with high common-mode voltages and currents. Its power-over-fiber architecture galvanically isolates the DUT from the measurement setup, providing a higher common-mode rejection ratio (CMRR) than conventional differential probes.
The oscilloscope probe delivers accurate differential measurements, offering an input and offset range of ±3 kV, a common mode range of ±60 kV, and a rise time of less than 450 ps. It suppresses fast common-mode signals that can distort and interfere with accuracy, achieving a CMRR of greater than 90 dB (30,000:1) at 1 GHz. Upgradeable bandwidth options for the probing system include 100 MHz, 200 MHz, 350 MHz, 500 MHz, and 1 GHz.
The RT-ZISO probing system connects to any oscilloscope with a BNC or SMA interface. However, it offers seamless operation and control when connected to an R&S oscilloscope. With a CAT III 1000-V safety rating, the RT-ZISO ensures reliable electrical measurements. Additionally, its safe-attach feature allows for easy and secure swapping of probe tips.
