The R&S RT-ZISO system enables accurate measurements of fast switching signals, especially in environments with high common-mode voltages and currents, according to the company. Its R&S RT-ZPMMCX passive probe with MMCX connector is also a new addition, designed to complement the system for low-side gate measurement tasks.
Rohde & Schwarz said the R&S RT-ZISO provides precise differential measurements of up to ±3 kV on reference voltages of ±60 kV with a rise time of < 450 ps and suppresses fast common-mode signals that can distort and interfere with accurate measurements. The power-over-fibre architecture galvanically isolates the device under test from the measurement setup, providing a much higher common-mode rejection ratio than conventional differential probes, noted the company.
Key features include bandwidth options of 100 MHz to 1 GHz (upgradeable), a CMRR of > 90 dB (> 30 000:1) at 1 GHz, an input and offset range of ±3 kV, a common mode range of ±60 kV, and a sensitive input range of ±10 mV.
The company claimed that with the next generation MXO series (MXO 4, MXO 5 and MXO 5C), the probe enables measurements with the “world’s fastest acquisition in the time and spectrum domain”, thanks to the oscilloscopes’ hardware-based acceleration. In combination with the R&S RTO6, design engineers can use the probe for complex analysis tasks using the oscilloscope’s “high performance and advanced measurement capabilities”.
R&S RT-ZISO is designed for various applications, including switching analysis of power converters with WBG materials, double-pulse testing, floating measurements, shunt measurements, inverter design and motor drive analysis.
