WFMInpre:XZEro
Description
This command sets or queries the sub --sample time between the trigger
sample (designated by PT_OFF) and the occurrence of the actual trig-
ger on the incoming waveform. This value is used to compute TTOFF
for the incoming waveform, and is expressed in terms of
WFMInpre:XUNit.

Syntax 2
WFMInpre:XZEro?
Argument
H <NR3>
This argument is a floating point value that ranges from --
WFMInpre:XINcr to 0.
Example 1
WFMInpre:XZEro?
This query might return
:WFMINPRE:XZEro 7.5000E-6
indicating that the trigger occurs 7.5 µs before the sample designated by
WFMInpre:PT_Off.
Example 2
WFMInpre:XZEro 5.7E-6
This command specifies that the trigger actually occurred 5.7 µs before
the sample designated by WFMInpre:PT_Off.
