SDS5000X Series Digital Oscilloscope User Manual
27 Power Analysis
27.1 Overview
The SDS5000X supports a power analysis function. Power analysis can help
users quickly and easily analyze and debug switching power supply design. It
automatically calculates Power Quality, Current Harmonics, Inrush Current,
Switching Loss, Slew Rate, Modulation, Turn On/Turn Off, Transient Response,
PSRR, Power Efficiency, Output Ripple, etc. Full use of the Power analysis
requires an SDS5000X oscilloscope with a firmware revision > 0.8.7R1B1, a
differential voltage probe like the SIGLENT DPB series, a current probe like the
SIGLENT CP series, the SIGLENT DF2001A deskew fixture, and the power
analysis activation license (part number SDS-5000X-PA). Install the software
option part number SDS-5000X-PA to permanently enable the power analysis
function. Please refer to the section " Install Option" for installation and
activation instructions.
