Commands Listed in Alphabetical Order
Arguments
CH1–CH4 specifi
es an analog channel as the I2C SDATA source waveform.
D0–D15 specifies a digital channel as the I2C SDATA source waveform.
(MSO/MDO4000
/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
BUS:B<x>:LABel
Specifies the waveform label for the bus.
Group
Bus
Syntax
BUS:B<x>:LABel <Qstring>
BUS:B<x>:LABel?
Arguments
<Qstring> is an alphanumeric string of text, enclosed in quotes, that contains the
text label information for bus <x>. The text string is limited to 30 characters.
BUS:B<x>:LIN:BITRate
Specifies the bit rate 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.
Group
Bus
Syntax
BUS:B<x>:LIN:BITRate <NR1>
BUS:B<x>:LIN:BITRate?
Arguments
<NR1> is the LIN bus bit rate. You can enter any positive integer, and the
instrument will coerce the value to the closest supported bit rate.
Examples
BUS:B1:LIN:BITRATE 9600 sets the bit rate 9600.
BUS:B1:LIN:BITRATE? might return BUS:B1:LIN:BITRATE 2400 indicating
the bit rate is set to 2400.

Bus
Syntax
BUS:B<x>:LIN:IDFORmat {NOPARity|PARity}
BUS:B<x>:LIN:IDFORmat?
Arguments
NOPARity sets the LIN bus ID format to no parity.
PARity sets the LIN bus ID format to parity.
Examples
BUS:B1:LIN:IDFORMAT PARITY sets the LIN bus ID format to parity.
BUS:B1:LIN:IDFORMAT? might return BUS:B1:LIN:IDFORMAT NOPARITY
indicating the LIN bus ID format is no parity.
BUS:B<x>:LIN:POLarity
Specifies the LIN bus polarity.

Syntax
BUS:B<x>:LIN:POLarity {NORMal|INVerted}
BUS:B<x>:LIN:POLarity?
Arguments
NORMal specifies normal polarity.
INVerted specifies inverted polarity.

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.
Group
Bus
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.
