TDS Family Oscilloscope Programmer Manual
NOTE. When returning WFMPRE:<wfm> information from the oscilloscope,
<wfm> specifies the waveform source (CH<x>, MATH<x>, or REF<x>). The
source must also be set using the DAta:SOUrce command. When sending
WFMPRE:<wfm> information to the scope, the <wfm> specification is ignored
and the reference location specified by DATa:DESTination is used instead.
WFMPre:<wfm>? (Query Only)
Returns the waveform formatting data for first ordered waveform as specified by
the DATa:SOUrce command. Channel and math waveforms must be displayed
before they can be queried. Querying an invalid reference waveform generates an
execution error.
