Waveform Transfer Command Group

Use the commands in the Waveform Tra nsfer 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 v alue 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.
