R&S bolsters power characterisation options for scopes

Rohde & Schwarz recently unveiled a new differential wideband probe along with its new power analysis options for its R&S RTO and R&S RTM oscilloscopes. The new R&S RT-ZD10 probe is especially ideal for the characterisation of switching power supplies with high clock frequencies, while the R&S RTO-K31 or R&S RTM-K31 option enables developers to automatically perform all major quality analyses and conveniently document the measurement results.

Advanced switching power supplies have ever-higher clock frequencies. The new R&S RT-ZD10 active differential wideband probe has proven especially useful for characterizing these power supplies. The probe combines a high bandwidth of 1GHz and a large input voltage range of 70VDC or 46VAC (peak). The common mode and differential offset compensation can be set separately from each other to increase the flexibility of the measurement.

The R&S RTO-K31 and R&S RTM-K31 power analysis options provide users with specialised measurement functions for automatically testing the quality of all segments of today's switching power supplies C including the mains voltage quality of the input range, the safe operating area (SOA) of the switching transistor as well as the magnitude and spectrum of the output ripple. A measurement wizard guides the user through all measuring steps and provides diagrams illustrating where to connect current probes and other probes to the device under test.

The R&S RT-ZF20 power deskew fixture allows automatic delay correction between the signals of the current probe and the voltage probe. The handy documentation feature helps users manage the measurement results and save the measurement documentation in RTF or PDF format.
