Waveform measurements
Waveform measurement readings sample the entire pulse. Sampling is performed on the rise time,
top width, and fall time portions of the pulse. In the figure below, 15 samples are performed on the
pulse waveform. Enabled voltage and current readings and time stamps are returned for every
sample taken on the pulse. The
NumPulses
(number of pulses) parameter is used to specify the
number of pulses to be output and sampled.
Figure 205: Waveform measurements
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 (see figure below). See
(on page 5-75) for details on measurement timing for pre-data and
post-data.
