Performance Analysis
This section of the Power Analyzer option provides tools to evaluate the performance of your power sup-
ply.
l
The Efficiency Test lets you measure input power, output power, and overall efficiency.
l
The Ripple Test measures ripple—including pk-pk, maximm, and minimum ripple—and generates
a spectral plot of the frequency content of the power supply's output.
Because of the varying ranges of voltages and currents of different power supply topologies, including
requirements to maintain isolation, please use the appropriate probes when performing these tests. Be
sure to maintain the proper probe setups and make fine adjustments to DC offsets and DeGuassing
using the Input Settings tab controls.
Performance Efficiency Test
This test checks the efficiency of the power conversion by computing power on output divided by power
at input.
Efficiency Test Setup
For input power, attach the voltage and current probes to the corresponding input sources shown
below. Ouput Power is measured using the voltage and current probes as shown below. Confirm the
Power Analyzer software input and output probe sources are matched to this setup.
