TRIGger:A:BUS:B<x>:MIL1553B:CONDition
Arguments
CH1–4 specifies an analog channel as the source for differential input.
MATH specifies the math waveform as the MIL-STD-1553 bus source for
differential input
REF1–4 specifies a reference waveform as the source for differential input.
Examples
BUS:B1:MIL1553B:SOUrce ref4 specifies to use reference waveform 4 as
the source.
BUS:B1:MIL1553B:SOUrce? might return CH2, indicating that channel 2 is
the currently specified source.
BUS:B<x>:PARallel:BIT<x>:SOUrce
Specifies the bit source waveform 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.
