INrange trigge
rs on an input value that is within a range set by two values.
OUTrange triggers on an input value that is outside of a range set by two values.
Examples
TRIGGER:A:BUS:B1:USB:QUALIFIER LESSTHAN sets the oscilloscope to
trigger when an address, data, or endpoint value is less than a set value.
TRIGGER:A:BUS:B1:USB:QUALIFIER? might return
:TRIGGER:A:BUS:B1:USB:QUALIFIER EQUAL indicating that the trigger
condition is to trigger when an address, data, or endpoint is equal to a set value.
TRIGger:A:BUS:B<x>:USB:SOFFRAMENUMber
This command specifies the binary data string to be used for start of frame
number, when the trigger condition is Token Packet and the token type is Start
of Frame.
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.
