Examples
BUS:B1:I2C:AD
DRESS:RWINCLUDE ON
includes the read/write bit in the
address.
BUS:B1:I2C:A
DDRESS:RWINCLUDE?
might return
BUS:B1:I2C:ADDRESS:RWINCLUDE 0 indicating the read/write bit is not
included in the address.
BUS:B<x>:I
2C{:CLOCk|:SCLk}:SOUrce
This command specifies the SCLK source for the I2C bus.
Conditions
This command requires a DPO4EMBD application module for 4000 series
models, and an MDO3EMBD application module for MDO3000 series models.

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:B<x>:LIN
:IDFORmat
Specifies the LIN bus ID format.
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: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.
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:POLarity {NORMal|INVerted}
BUS:B<x>:LIN:POLarity?
Arguments
NORMal specifies normal polarity.
INVerted specifies inverted polarity.
