Arguments
LESSthan indicates the oscilloscope will search for a value that is less than a
set value.
MOREthan indicates the oscilloscope will search for a value that is greater than a
set value.
EQual indicates the oscilloscope will search for a value that is equal to a set value.
UNEQual indicates the oscilloscope will search for a value that is not equal to a
set value.

set by two values.
OUTrange indicates the oscilloscope will search for a value that is outside of a
range set by two values.
Examples
SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:QUALIFIER LESSTHAN sets the
oscilloscope to search when an address, data, or endpoint value is less thana
set value.
SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:QUALIFIER? might return
:SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:QUALIFIER EQUAL indicating
that the search condition is to search when an address, data, or endpoint is equal
to a set value.
