The Rohde & Schwarz oscilloscope accessories portfolio now includes the new R&S RT-ZC20B current probe with the Rohde & Schwarz probe interface. Via this interface, R&S RTO, R&S RTE, and R&S RTM oscilloscopes automatically detect up to four current probes connected in parallel. The instruments also automatically adjust the vertical scaling and zeroing settings. The degaussing function is activated directly on the instrument.
The current probe receives power over the Rohde & Schwarz probe interface, eliminating the need for an external power supply. At 100-MHz bandwidth, the R&S RT-ZC20B can measure AC and DC of a maximum 30-A RMS or 50-A peak current with a resolution of 10 mA and low noise. Combined with the R&S RTO/R&S RTE 16-bit high-definition option, currents less than 1 mA can also be measured. This makes the current probe suitable for numerous power electronics applications, especially for evaluating switched-mode power supplies that require measurement of high-frequency current components.
