Spot mean average readings
For this data acquisition type, each returned reading is a mean-of-the-means. Spot mean average
averages the mean readings for all the pulses in the burst. In the figure in Spot mean discrete
readings (on page 4-24), each mean reading for pulse 1 is averaged with each corresponding mean
reading for pulse 2 to yield the mean-of-the-means readings shown below. With all voltage and
current readings enabled, four readings are returned for the burst. When time stamps are enabled, a
timestamp is included in the data set after each mean-of-the-means reading.

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.
