Commands Listed in Alphabetical Order
Arguments
ANY indicates t
he oscilloscope will trigger on any handshake type.
NAK indicates the oscilloscope will trigger when a device cannot send or receive
data.
ACK indicates the oscilloscope will trigger when a packet is successfully received.
STALL indicates the oscilloscope will trigger when a device requires intervention
from the host.
Examples
TRIGGER:A:BUS:B1:USB:HANDSHAKETYPE ACK sets the handshake type to
acknowledgement.
TRIGGER:A:BUS:B1:USB:HANDSHAKETYPE? might return
:TRIGGER:A:BUS:B1:USB:HANDSHAKETYPE STALL, indicating that
the handshake type is set to stall.
TRIGger:A:BUS:B<x>:USB:QUALifier
This command specifies the USB trigger qualifier for address, endpoint and data.
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.
