RJ specifies the
right justified audio format.
TDM specifies the time-division multiplexing audio format.
Examples
BUS:B1:AUDIO:TYPE RJ sets right-justified as the audio format.
BUS:B1:AUDIO:TYPE? might return :BUS:B1:AUDIO:TYPE I2S indicating
that the audio format is set to I
2
S.
BUS:B<x>:AUDio:WORDSel:POLarity
Specifies the word select polarity for the AUDIO bus.
Conditions
This command requires the DPO4AUDIO application module for the
MDO4000/B/C series, or the MDO3AUDIO for MDO3000 series.

Syntax
BUS:B<x>:AUDio:WORDSel:POLarity {NORMal|INVERTed}
BUS:B<x>:AUDio:WORDSel:POLarity?
Arguments
NORMal specifies positive WORDSel polarity.
INVERTed specifies negative WORDSel polarity.
Examples
BUS:B1:AUDIO:WORDSEL:POLARITY NORMal sets normal as the word select
polarity.
BUS:B1:AUDIO:WORDSEl:POLARITY? might return
:BUS:B1:AUDIO:WORDSEL:POLARITY NORMAL indicating that the word select
polarity is set to normal.
BUS:B<x>:AUDio:WORDSel:SOUrce
Specifies the word select source waveform for the AUDIO bus.
Conditions
This command requires the DPO4AUDIO application module for the
MDO4000/B/C series, or the MDO3AUDIO for MDO3000 series.

io:WORDSel:SOUrce?
Arguments
CH1–CH4 specifies an analog channel as the word select source waveform .
D0-D15 specifies a digital channel as the word select source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO installed.)
Examples
BUS:B1:AUDIO:WORDSEL:SOURCE CH1 sets CH1 as the word select source.
BUS:B1:AUDIO:WORDSEL:SOURCE? might return
:BUS:B1:AUDIO:WORDSEL:SOURCE CH2 indicating that the word select source
is set to CH2.
BUS:B<x>:CAN:BITRate
Specifies the bit rate for the CAN bus.
Conditions
This command requires a DPO4AUTO or DPO4AUTOMAX application
module for all 4000 series models, or the MDO3AUTO application module for
MDO3000 series models.
Group
Bus
Syntax
BUS:B<x>:CAN:BITRate <NR1>
BUS:B<x>:CAN:BITRate?
Arguments
<NR1> is the bit rate. The instrument supports bit rates at 10 bps intervals. You
can enter any positive integer
, and the instrument will coerce the value to the
closest supported bit rate.
Returns
The query always returns the numerical bit rate value.
Examples
bus:b1:can:bitrate 50000 sets the CAN bit rate to 50000.
bus:b1:can:bitrate? might return :BUS:B1:CAN: BITRATE 50000
indicating the bit rate is set to 50K.

BUS:B<x>:CAN
:FD:BITRate
Specifies the FD bit rate for the CAN bus. This is the bitrate used for CAN FD
frames transmitted with increased data phase rates. The maximum bitrate for
MDO3000 mode
ls is 7 Mbps. The maximum bitrate for MDO4000C models
is 10 Mbps.
Conditions
This feat
ure requires installation of a DPO4AUTO or DPO4AUTOMAX
application module for MDO4000C models, or MDO3AUTO for MDO3000
models.

BUS:B<x>:CAN:FD:BITRate?
Arguments
<NR1> is the FD bit rate. The instrument supports bit rates at 100 bps intervals.
You can enter any positive integer, and the instrument will coerce the valueto
the closest supported bit rate.
Returns
The query always returns the numerical FD bit rate value.
Examples
BUS:B1:CAN:FD:BITRate 2000000 sets the FD bit rate to 2000000.
BUS:B1:CAN:FD:BITRate? might return 4000000, indicating that the FD bit
rate is 4 Mbps.
BUS:B<x>:CAN:FD:STANDard
Specifies the CAN FD standard to use.
Conditions
This feature requires installation of a DPO4AUTO or DPO4AUTOMAX
application module for MDO4000C models, or MDO3AUTO for MDO3000
models.
