Power Supply Test Software
for Infiniium MXR-Series Oscilloscopes
D9010PWRA - Power Supply Analysis (Input, Switching, Output, SOA)
Power supply analysis is easy with Keysight’s Infiniium MXR-Series
oscilloscopes with the optional D9010PWRA software. The broad range of
automated power supply characterization measurements including critical
frequency response measurements such as power supply rejection ratio (PSRR)
and control loop response (Bode plots). The Infiniium MXR-Series oscilloscopes
also support multi-channel waveform mask testing for detailed analysis of supply
system turn-on/turn-off testing of up to 8 power supply lines.
