:POWer:PSRR:APPLy
Command Syntax
:POWer:PSRR:APPLy
The :POWer:PSRR:APPLy command applies the power supply rejection ratio
(PSRR) analysis.
The Power Supply Rejection Ratio (PSRR) test is used to determine how well a
voltage regulator rejects ripple noise over different frequency range.
This analysis provides a signal from the oscilloscope's waveform generator that
sweeps its frequency. This signal is used to inject ripple to the DC voltage that
feeds the voltage regulator.
The AC RMS ratio of the input over the output is measured and is plotted over the
range of frequencies.
It takes some time for the frequency sweep analysis to complete. You can query bit
0 of the Standard Event Status Register (*ESR?) to find out when the analysis is
complete.
You can use the :POWer:PSRR:TRACe command to specify whether to include gain
data in the PSRR analysis results.
