BUS:B<x>:MIL1553B:SOUrce
Arguments
NORMal - A high-low transition represents a 1 on the Data+ line.
INVERTed - A high-low transition represents a 0 on the Data+ line.
Examples
BUS:B1:MIL1553B:POLarity INVERTED sets the polarity so that a high-low
transition represents a 0 on the Data+ line.
BUS:B1:MIL1553B:POLarity? might return NORMAL.
BUS:B<x>:MIL1553B:RESPonsetime:MAXimum
This command specifies the maximum response time to a valid command issued
for the MIL-STD-1553 bus.
NOTE. The MIL-STD-1553 bus specifi cation requires devices to respond to a
valid command within 4 to 12 microseconds.
Conditions
This command requires a DPO4AERO application module for 4000 series models,
and an MDO3AERO application module for MDO3000 series models.

Arguments
<NR3> is a floating point number that specifies the minimum response time in
seconds.
Examples
BUS:B1:MIL1553B:RESPonsetime:MINimum 4.0E-6 specifies the minimum
responsetimetoavalidcommandreceivedto4.0E-6microseconds.
BUS:B1:MIL1553B:RESPonsetime:MINimum? might return 4.0000E-6.
BUS:B<x>:MIL1553B:SOUrce
This command specifies the source for differential input for the MIL-STD-1553
bus. The supported source waveforms are channels 1–4, math waveform, and
reference waveforms 1–4. The default is channel 1.
Conditions
This command requires a DPO4AERO application module for 4000 series models,
and an MDO3AERO application module for MDO3000 series models.

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.
