Arguments
CH1–4 specifies to use one of the analog channels as the source waveform.
MATH specifies to use the math waveform astheasthesourcewaveform.
REF1–4 specifies to use one of the reference waveforms 1–4 as the as the source
waveform.

Examples
SEARCH:SEARCH1:TRIGger:A:TIMEOut:SOUrce CH4 specifies to use
channel 4 as the source for the timeout search.
SEARCH:SEARCH1:TRIGger:A:TIMEOut:SOUrce? might return CH1,
indicating that channel 1 has been set as the source for the timeout search.
SEARCH:SEARCH<x>:TRIGger:A:TIMEOut:TIMe
When searching using the TIMEOut search type, this command specifies the
timeout time, in seconds. The default and minimum is 4.0E-9 seconds and the
maximum is 8.0 seconds. The resolution is 800.0E-12 which means that the
increments of time specified is 800 picoseconds. The timeout search type is

Arguments
<NR3> is a floating point number that specifies the timeout time, in seconds. The
default is 8.0000E-9.
Examples
SEARCH:SEARCH1:TRIGger:A:TIMEOut:TIMe 4.0E-9 specifies the timeout
time of 4.0 nsec.
SEARCH:SEARCH1:TRIGger:A:TIMEOut:TIMe? might return 8.0000E-9,
which is the default.

{EITher|NEGative|POSitive}
SEARCH:SEARCH<x>:TRIGger:A{:TRANsition|:RISEFall}:POLarity?
Arguments
POSitive specifies that a pulse edge must traverse from the lower (most
negative) to higher (most positive) level for transition searching to occur.
NEGative specifies that a pulse edge must traverse from the upper (most positive)
to lower (most negative) level for transition searching to occur.
EITher specifies either positive or negative polarity.
