Measure modes
The measure modes for the PMU are discrete pulses and average pulses..
Discrete pulses
For pulse I-V (spot mean), the averaged voltage or current readings for every sampled pulse period
are acquired.
For waveform capture, enabled voltage and current readings and timestamps for every sample of the
waveform are acquired.
For ITM operation, the readings are placed in the Analyze sheet.
(on page 4-24) for details on the discrete pulses measure mode for
pulse I-V. For UTM programming, the discrete pulse measure mode is called spot mean discrete.
The
pulse_meas_sm
function is used to select the discrete acquisition type.
(on page 4-26) for details on the discrete pulses measure mode for
waveform capture. For UTM programming, the discrete pulse measure mode is called waveform
discrete. The
pulse_meas_wfm
function is used to select the discrete acquisition type.
Average pulses
For pulse I-V (spot mean), the mean values of two or more pulses are averaged. Think of it as the
"mean of the means."
For waveform capture, each acquired reading is a mean average of the corresponding samples for all
the pulses in the burst.
(on page 4-25) for details on the average pulses measure mode
for pulse I-V. For UTM programming, the average pulse measure mode is called spot mean average.
The
pulse_meas_sm
function is used to select the average acquisition type.
(on page 4-27) for details on the average pulses measure mode for
waveform capture. For UTM programming, the average pulses measure mode is called waveform
discrete. The
pulse_meas_wfm
function is used to select the average acquisition type.
