Commands Listed in Alphabetical Order
Arguments
CH1–CH4 specifi
es an analog channel as the source waveform.
D0-D15 specifies a digital channel as the source waveform.
(MSO/MDO4000
/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
Examples
BUS:B1:LIN:SOURCE CH4 sets the source waveform to channel 4.
BUS:B1:LIN:SOURCE? might return BUS:B1: LIN:SOURCE CH1 indicating the
source waveform is channel 1.
BUS:B<x>:LIN:STANDard
Specifies the LIN bus standard to use.
Conditions
This command requires a DPO4AUTO or DPO4AUTOMAX application
module for all 4000 series models, and the MDO3AUTO application module
for MDO3000 series models.

Syntax
BUS:B<x>:LIN:STANDard {V1X|V2X|MIXed}
BUS:B<x>:LIN:STANDard?
Arguments
V1X sets the LIN bus standard to V1X.
V2X sets the LIN bus standard to V2X
MIXed sets the LIN bus standard to MIXED.
Examples
BUS:B1:LIN:STANDARD V1X sets the LIN bus standard is V1X.
BUS:B1:LIN:STAND
ARD?
might return BUS:B1:LIN:STANDARD V2X
indicating the LIN bus standard is V2X.
BUS:B<x>:MIL1553B:POLarity
This command set
s the polarity of the MIL-STD-1553 bus (normal or inverted).
Conditions
This command requires a DPO4AERO application module for 4000 series models,
and an MDO3AERO application module for M
DO3000 series models.

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.
