Arguments
ANY indicates the oscilloscope will search for any handshake type.
NAK indicates the oscilloscope will search for when a device cannot send or
receive data.
ACK indicates the oscilloscope will search for when a packet is successfully
received.
STALL indicates the oscilloscope will search for when a device requires
intervention from the host.
Examples
SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:HANDSHAKETYPE ACK sets the
handshake type to acknowledgement.
SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:HANDSHAKETYPE? might return
:SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:HANDSHAKETYPE STALL,
indicating that the handshake type is set to stall.

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.
LESSEQual indicates the oscilloscope will search for a value that is less than
or equal to a set value.
MOREEQual indicates the oscilloscope will search for a value that is greater than
or equal to a set value.
INrange indicates the oscilloscope will search for a value that is within a range
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.
SEARCH:SEARCH<x>:TRIGger:A:BUS:B<x>:USB:SOFFRAMENUMber
This command specifies the value for the start of frame to be used in a USB search,
when the search condition is set to
TOKENPacket, and the token type is set to SOF
(Start of Frame). S EARCH<x> is the search number, which is always 1, and B< x>
