Commands Listed in Alphabetical Order
Arguments
CH1–CH4 specifi
es an analog channel as the bit source waveform.
D0-D15 specifies a digital channel as the bit source waveform.
(MSO/MDO4000
/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
BUS:B<x>:PARallel:CLOCk:EDGE
Specifies the clock edge for the parallel bus.
Conditions
Requires an MSO/MDO model, with the MDO3MSO option installed for the
MDO3000 series. The MSO4000B and MDO4000/B/C models can trigger on
parallel buses without an application module.
