WAVFrm? (Query Only)
Returns WFMOutpre? and CURVe? data for the waveform as specified by
the DATA:SOUrce c o mmand. This command is equivalent to sending both
WFMOutpre? and CURVe?, with the additional provision that the response to
WAVFrm? is guaranteed to provide a synchronized preamble and curve. The
source waveform, as specified by :DATA:SOURCE, must be active or the query
will not return any data and will generate an error indicator.
NOTE. For MSO models, reduced resolution waveform data is not available for
the digital channels.
