Examples
BUS:B1:LIN:PO
LARITY IN VERTED
sets the polarity to INVERTED.
BUS:B1:LIN:POLARITY? might return BUS:B1:LIN:P OLARITY NORMA L
indicating the polarity is normal.
BUS:B<x>:LIN:SAMPLEpoint
Specifies the point to sample during each bit period, as a percent, for the LINbus.
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:SAMPLEpoint <NR1>
BUS:B<x>:LIN:SAMPLEpoint?
Arguments
<NR1> is a percentage that represents the point at which to sample during each
bit period.
Examples
BUS:B1:LIN:SAMPLEPOINT 10 sets the sample point to 10% of the bit period
BUS:B1:LIN:SAMPLEPOINT? might return BUS:B1:LIN:SAMPLEPOINT 50
indicating that the sample point is set to 50% of the bit period
BUS:B<x>:LIN:SOUrce
Specifies the source waveform for the LIN bus.
Conditions
This command requires a DPO4AUTO or DPO4AUTOMAX application
module for all 4000 series models, and the MDO3AUTO application module
for MDO3000 series models.

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.

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
