: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.
