SEARCH:SEARCH<x>:TRIGger:A:RUNT:WHEn?
Arguments
LESSthan argument sets the oscilloscope to search if the a runt pulse is detected
with width less than the time set by the SEARCH:SEARCH<x>:TRIGger:A:
RUNT:WIDth command.
than argument sets the oscilloscope to search if the a runt pulse is detected with
width than the time set by the SEARCH:SEARCH<x>:TRIGger:A:RUNT:WIDth
command.
EQual argument sets the oscilloscope to search when the pattern is true for a time
period equal to the time period specified in SEARCH:SEARCH<x>:TRIGger:A:
RUNT:WIDth within a ±5% tolerance.
UNEQual argument sets the oscilloscope to search when the pattern is true for a
time period greater than or less than (but not equal) the time period specified in
SEARCH:SEARCH<x>:TRIGger:A:RUNT:WIDth within a ±5% tolerance.
OCCURS argument specifies a search event if a runt of any detectable width occurs.
SEARCH:SEARCH<x>:TRIGger:A:RUNT:WIDth
This command specifies the width setting for a runt search to determine whereto
place a mark.
SEARCH<x> is the search number, which is always 1.
