TVS600 & TVS600A Command Reference
DATA:PREamble? (Query Only)
Returns the data preamble for the specified function or for all enabled sense
functions. If auto-advance acquisition is on, then one preamble for each enabled
channel is returned.
When you specify a sense function, DATA:PREamble? returns only the preamble
of the specified function. When no sense function is specified,
DATA:PREamble? returns the preambles of all enabled sense functions. The
preambles are returned in ascending channel order.
DATA:PREamble? does not return data until pending acquisitions or calculations
are complete. You can use the commands *WAI, *OPC, or *OPC? to synchro-
nize the response in a different manner.
Channel names and function strings may be used interchangeably for parameters.
This is not standard SCPI practice and does not provide horizontal compatibility.
