SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:USB:CONDition
This command specifies the search condition for a USB search. SEARC H<x> is the
search number, which is always 1, and
B<x>
Conditions
This command requires the DPO4USB application module to be installed, except
for MDO3000 models, which require the MDO3USB. Note that 1 GHz bandwidth
models are recommended for high-speed (HS) USB.

1:TRIGGER:A:BUS:B1:USB:CONDITION TOKENPACKET
sets
the search condition to be a token packet.
SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:CONDITION? might return
:SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:CONDITION SYNC,which
indicates that the search condition is a sync field.
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:USB:DATa:HIVALue
This command specifies the upper limit data value for the inside-of-range
and outside-of-range qualifiers to be used in a USB search, when
the search condition is set to
DATAPacket. Use the command
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:USB:DATa:VALue to set the
lower limit.
SEARCH<x> is the search number, which is always 1, and B<x>
