SEARCH:SEARCH<x>:TRIGger:A:SETHold:DATa:THReshold
This command specifies the data threshold setting for an setup/hold search to
determine where to place a mark.
SEARCH<x> is the search number, which is
always 1.

{<NR3>|TTL}
SEARCH:SEARCH<x>:TRIGger:A:SETHold:DATa:THReshold?
Arguments
TTL specifies a preset TTL high level of 1.4 V.
<NR3> is a floating point number that specifies the clock level, in volts.
SEARCH:SEARCH<x>:TRIGger:A:SETHold:HOLDTime
This command specifies the hold time setting for an setup/hold search to determine
wheretoplaceamark.

Syntax
SEARCH:SEARCH<x>:TRIGger:A:SETHold:HOLDTime <NR3>
SEARCH:SEARCH<x>:TRIGger:A:SETHold:HOLDTime?
Arguments
<NR3> is a floating point number that specifies the hold time setting in seconds.
Positive values for hold time occur after the clock edge. Negative values occur
before the clock edge.

SEARCH:SEARCH<x>:TRIGger:A:SETHold:THReshold{:MATH|:MATH1}?
Arguments
<NR3> is a floating point number that specifies the lower threshold in volts.
SEARCH:SEARCH<x>:TRIGger:A:SETHold:THReshold:REF<x>
This command specifies the search setup and hold threshold for the selected
reference waveform. This helps to determine where to place search marks.
Search<x> is the search number, which is always 1. REF<x> is the reference
waveform number, which can be 1–4.

<NR3> is a floating point number that specifies the lower threshold in volts.
SEARCH:SEARCH<x>:TRIGger:A:TIMEOut:POLarity
When searching using the TIMEOut search type, this commands specifies the
polarity to be used. Use the command SEARCH:SEARCH<x>:TRIGger:A:TYPe
to specify the timeout search type.
SEARCH<x> is the search number, which is
always 1.

SEARCH:SEARCH<x>:TRIGger:A:TIMEOut:SOUrce
SEARCH:SEARCH<x>:TRIGger:A:TIMEOut:TIMe
Arguments
STAYSHigh — Search when the polarity stays high during the timeout time.
STAYSLow — Search when the polarity stays low during the timeout time.
EITher — Search when the polarity is either high or low.
Examples
SEARCH:SEARCH1:TRIGger:A:TIMEOut:POLarity STAYSHigh specifies to
search for the condition that the polarity stays high during the timeout time.
SEARCH:SEARCH1:TRIGger:A:TIMEOut:POLarity? might return EITHER.
This indicates that the search has been set for timeout when the polarity remains
either high or low for longer than the specified timeout time.
SEARCH:SEARCH<x>:TRIGger:A:TIMEOut:SOUrce
When searching using the TI MEOut search type, this command specifies the
source. The available sources are live channels, reference waveforms, themath
waveform, or the digital channels. The default is channel 1. The timeout search
