The number of samples taken on the amplitude and base level is dependent on the size of the
portions to be sampled and the sampling rate. Use the pulse_sample_rate function to set the
sampling rate for pulse measurements.
Figure 99: Spot mean measurements example
Waveform measurement timing
The waveform measurement type samples the pulse as shown in Waveform measurements (on page
4-25). Sampling is performed on the entire duration (100%) of the pulse. This includes the rise time,
amplitude, and fall time portions of the pulse. A voltage and/or current reading is returned for every
sample.
A waveform measurement can include pre-data and post-data. Pre-data is extra data taken before
the rise time of the pulse; post-data is extra data taken after the fall time. Waveform measurements
(on page 4-25) shows an example where 10% (0.1) pre-data and 10% (0.1) post-data is taken.
The number of samples taken on the pulse is dependent on the size of the pulse to be sampled and
the sampling rate. Use the pulse_sample_rate function to set the sampling rate for pulse
measurements.
In the function, a percentage must be expressed as its decimal equivalent. For example, specify 50%
as 0.5 in the function.
