WFMOutpre:XZEro?
Description
This query--only command returns the sub--sample time between the
trigger sample (designated by PT_OFF) and the occurrence of the actu-
al trigger for the waveform specified by the DATa:SOUrce command.
This value is in units of WFMOutpre:XUNit.
An error is reported if the DATa:SOUrce waveform does not exist.
Note: During stopped state operation (i.e., ACQuire:STATE OFF), this
is the only preamble that changes on each acquisition. If a query is run
during steady state operation (that is, all control changes have settled
and triggers are arriving on a regular basis), the XZEro value of the last
stopped state is returned.
