Waveform Transfer Command Group
Use the commands in the Waveform Transfer Command Group to transfer
waveform data points to and from the oscilloscope. Waveform data points are a
collection of values that define a waveform. One data value usually represents
one data point in the waveform record. When working with envelope waveforms,
each data value is either the minimum or maximum of a min/max pair.
Before you transfer waveform data, you must specify the data format, record
length, and waveform source or destination.
