HORizontal:FASTframe:XZEro:FRAme:REF<x>?
Description
This query--only command returns xzero for the specified frame. The
reference waveform is specified by x. The value of x can range from 1
through 4 for four-channel instruments or 1 through 2 for two-channel
instruments.
Xzero is the subsample time between the trigger sample (designated by
WFMOutpre:PT_Off?) and the occurrence of the actual trigger for the
waveform specified.

Syntax
HORizontal:FASTframe:XZEro:FRAme:REF<x>? <NR1>
Argument
<NR1>
The frame number for which the xzero will be returned on the speci-
fied waveform.
Example
