Rohde & Schwarz Oscilloscopes Add Power Options
September 30, 2013. When performing analyses on clocked power supplies, users can make use of the high sensitivity and dynamic range of the R&S RTO and R&S RTM oscilloscopes, allowing output ripple of power supplies to be characterized exactly and small voltages or currents in converters to be measured with precision.
The new R&S RTO-K31 and R&S RTM K31 power-analysis options provide users with specialized 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, and 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 new R&S RT ZD10 active differential wideband probe is useful for characterizing 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). The common mode and differential offset compensation can be set separately from each other to increase the flexibility of the measurement.
When it comes to the measurement of clocked power supplies, Rohde & Schwarz offers a portfolio comprising the R&S RTO and R&S RTM oscilloscopes, automatic power analysis options, and an assortment of voltage probes, current probes and accessories.
