measurements.
There are four types of pulse measurements that are performed by the Model
4225-PMU: Spot mean discrete, spot mean average, waveform discrete, and waveform
average. Use the following pulse generator functions to configure pulse measurements:
• Use the pulse_meas_sm function to configure spot mean measurements; select the
data acquisition type, set the readings to be returned, enable or disable time stamp,
and set LLEC. See Spot mean measurements
• Use the pulse_meas_wfm function to configure waveform measurements; select the
data acquisition type, set the readings to be returned, enable or disable time stamp,
and set LLEC. See Waveform measurements
• Use the pulse_meas_timing function to set measurement timing. For spot mean
measurements, portions of the amplitude and base levels are specified for sampling.
For pre-data and post-data waveform measurements, a percentage of the entire
pulse duration is specified. See
measurement timing.
Before calling the pulse_meas_timing function, use the pulse_meas_sm
NOTE
or pulse_meas_wfm function to configure the measurement type.
Measurement types
There are two types of pulse measurements: Spot mean and waveform. The
pulse_meas_sm function is used to configure
pulse_meas_wfm function is used to configure
