TRIGGER:A:BUS
:B1:USB:ADDRESS:VALUE?
might return
:TRIGGER:A:BUS:B1:USB:ADDRESS:VALUE “1000000”,which
indicates that the binary address is 100000 (40 hex).
TRIGger:A:B
US:B<x>:USB:CONDition
This command specifies the trigger condition for the USB trigger. 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.

TRIGger:A:BU
S:B<x>:USB:DATa:HIVALue
This command specifies the binary data string for the upper limit for inside-of-range
and outside-of-range qualifiers for the USB trigger when the trigger condition is
DATAPacket.
Use the command TRIGger:A:BUS:B<x>:USB:DATa:VALue
to set the lower limit.
