Commands Listed in Alphabetical Order
Arguments
ANY indicates a
ny of the token types.
SOF indicates a SOF (start-of-frame) token type
OUT indicates an OUT token type.
IN indicates an IN token type.
SETUP indicates a SETUP token type.
Examples
SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:TOKENTYPE SETUP sets the
token type to SETUP.
SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:TOKENTYPE? might return
:SEARCH:SEARCH1:TRIGGER:A:BUS:B1:USB:TOKENTYPE SOF if the token
type is SOF.
SEARCH:SEARCH<x>:TRIGger:A:BUS:SOUrce
This command specifies the source of a bus search. <x> is the search number.
SEARCH<x> is the search number, which is always 1.
