TLS 216 Programmer Manual
NOTE. When returning WFMPRE:<wfm> information from the logic scope,
<wfm> specifies the waveform source (CH<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 reference waveforms must be
displayed before they can be queried. Querying an invalid reference waveform
generates an execution error.
