16.4.1.1 Modulation analysis results
The results of "Modulation Analysis " measurements are provided in two ways:
●
The diagram shows the graphical presentation of:
– the voltage or the current waveform
– for "Type >Turn on" a track of the frequency and the duty cycle.
●
(Optional for "Type > Continuous" measurement) Two histograms display the den-
sity distribution of the measurement results in dependence of the frequency and
the positive duty cycle.
●
The result box displays the numeric measurement results.
To measure and display the power quality, the instrument uses the following measure-
ments and waveforms:
●
"Meas 7" to measure the positive duty cycle
●
"Meas 8" to measure the frequency
The used resources are listed in the "Details" tab. See also: Chapter 16.2.3, "Details
tab", on page 966.

Label Description
Current Currently measured value
+Peak Positive peak value (maximum)
-Peak Negative peak value (minimum)
μ (Avg) Average
RMS Root mean square
σ (S-dev) Standard deviation
Event count Number of measured pulses
Wave count Number of waveforms (acquisitions) the measurement is based on
"Modulation Analysis" is a statistical evaluation that is reset only if the measurement
setup is changed or you reset the statistics.
The following remote commands are used for handling the measurement results:
●
POWer:MODulation:RESult:ACTual? on page 1958
●
POWer:MODulation:RESult:AVG? on page 1958
●
POWer:MODulation:RESult:EVTCount? on page 1958
