Optimize scaling
Selects the scaling for the display of the results.
"Autoscale the signals"
Automatically selects the most appropriate scale for the display of the
results.
"Keep present settings"
The present display settings are not changed.
Remote command:
POWer:EFFiciency:AUTO on page 1970
Report comment
In this field you can write a comment that is displayed in the measurement report, for
example, a measurement description.
Execute
Starts the " Power Effieciency" measurement.
Remote command:
POWer:EFFiciency:EXECute on page 1971
16.6 Output
The "Output" measurements are used for characterizing the behavior and quality of the
SMPS output voltage.
16.6.1 Output ripple
The "Output Ripple" analysis measures the ripple of the device output. You can mea-
sure the voltage ripple alone or the voltage and the current ripple simultaneously. In
this measurement, the peak-to peak extremes of the output DC signal are of interest.
The measurement also includes the AC-RMS of the output DC signal, that is calculated
as a standard derivation.
Required probes:
●
Voltage probe
●
(Optional) Current probe
16.6.1.1 Output ripple results
The results of "Output Ripple" measurements are provided in two ways:
●
The diagram shows the graphical presentation of:
– the voltage waveform
– (optional) the current waveform
●
The result box displays the numeric measurement results for the voltage and for
the current ripple. For details, see Table 16-5 and Table 16-2.
