SEARCH:SEARC
H<x>:LIST? (Query Only)
This query returns a list of all automatically created search marks on waveforms
in the time domain (leaving out any manually created marks). These automatic
marks are cre
ated using a search command. The entries returned are in the form
of an enumeration representing the source waveform, followed by 7 time mark
parameters.
SEARCH<x> is the search number, which is always 1. To return a list
of manual marks, use the query form of MARK:USERLIST.
NOTE. A series of example command sequences showing d ifferent searches and
triggers is included as an appendix. (See page F-1, Search and Trigger Command
Sequence
Examples.)

Returns
The query is returned in the form: (
<Enum>,<NR3>,<NR3>,<NR3>,<NR3>,<NR3>,<NR3>,<NR3>) ..
<Enum> is the source waveform.
The 7 NR3 time mark parameters returned are as follows:
Start — start value in percent of record
End — end value in percent of record
Focus — focus value in percent of record
X value — horizontal value of the focus point in the mark’s waveform units
Y value — vertical value of the focus point in the mark’s waveform units
Delta X value — always 0, since there is no time-domain reference mark.
Delta Y value — always 0, since there is no time-domain reference mark.

Syntax
SEARCH:SEARCH<x>:STATE {<NR1>|OFF|ON}
SEARCH:SEARCH<x>:STATE?
Arguments
OFF or <NR1> = 0 sets the search state to off.
ON or <NR1> ≠ 0 sets the search state to on.
SEARCH:SEARCH<x>:TOTal? (Query Only)
Returns the total number of matches for the search. The total number of matches
may be than the number of marks placed. <x> is the search number, which
is always 1.
NOTE. A series of example command s equences showing different searches and
triggers is included as an appendix. (See page F-1, Search and Trigger Command
Sequence Examples.)

SEARCH:SEARCH<x>:TOTal?
Returns
<NR1> is the total number of matches.
SEARCH:SEARCH<x>:TRIGger:A:BUS? (Query Only)
Queries the SEARCH:SEARCH< x>:TRIGger:A:BUS settings. <x> is the search
number, which is always 1. There are four buses, B1 through B4, except for
MDO3000, which only has two buses, B1–B2.
To set the search type to bus, use SEARCH:SEARCH<x>:TRIGger:A:TYPe BUS.
