Rohde & Schwarz 'scopes add options and probes, for power analysis

October 01, 2013 // By Graham Prophet
Rohde & Schwarz has added power analysis options and a new differential wideband probe to its portfolio of analysis solutions for clocked power supplies.

Developers can use the R&S RTO-K31 or R&S RTM-K31 option to automatically perform all major quality analyses and conveniently document the measurement results. The new R&S RT ZD10 probe is suitable for characterisation of switching power supplies with high clock frequencies. High measurement sensitivity and dynamic range allows the output ripple of power supplies to be characterised exactly and small voltages or currents in converters to be measured with precision.

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 – 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 documentation feature helps users manage the measurement results and save the measurement documentation in RTF or PDF format

 

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