Commands Listed in Alphabetical Order
Arguments
ISO sets the CAN
FD standard to ISO CAN FD (11898-1:2015)
NONISO sets the CAN FD standard to non-ISO CAN FD (Bosch:2012)
Examples
BUS:B1:CAN:FD:STANDard ISO sets the CAN FD standard to ISO CAN FD.
BUS:B1:CAN:FD:STANDard? might return :BUS:B1:CAN:FD:STANDARD
NONISO, indicating that the CAN FD standard is non-ISO CAN FD.
BUS:B<x>:CAN:PRObe
Specifies the probing method 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.

Bus
Syntax
BUS:B<x>:CAN:PRObe {CANH|CANL|RX|TX|DIFFerential}
BUS:B<x>:CAN:PRObe?
Arguments
CANH specifies the single-ended CANH signal, as specified by the CAN standard.
CANL specifies the single-ended CANL signal, as specified by the CAN standard.
RX specifies the receive signal on the bus side of the CAN transceiver.
TX specifies the transmit signal.
DIFFerential specifies the differential CAN signal.
BUS:B<x>:CAN:SAMPLEpoint
Specifies the sampling point, as a percent, to sample during each bit period for
the CAN bus.
Conditions
This command requires a DPO4AUTO or DPO4AUTOMAX application
module for all 4000 series models, and the MDO3AUTO application module
for MDO3000 series m
odels.

Commands Listed in Alphabetical Order
Syntax
BUS:B<x>:CAN:
SAMPLEpoint <NR1>
BUS:B<x>:CAN:SAMPLEpoint?
Arguments
<NR1> is the sample point in percent. Values can be any integer from 5 to 95.
For a CAN 2.0 bus the allowable sample point range is 5% to 95%.
For a CAN FD bus the allowable sample point range is 15% to 95%.
NOTE. CAN FD requires an accurately specied sample point for correct decode
and triggering.
NOTE. CAN FD uses the same sample point percentage for bits transmitted at SD
bit rates and FD bit rates. For optimal performance, set the sample point to the
value used for SD bits (the "Arbitration Phase" sample point).
BUS:B<x>:CAN:SOUrce
Specifies the CAN bus data source.
Conditions
This command requires a DPO4AUTO or DPO4AUTOMAX application
module for all 4000 series models, and the MDO3AUTO application module
for MDO3000 series models.

BUS:B<x>:CAN:SOUrce?
Arguments
CH1–CH4 specifies an analog channel as the data source waveform.
D0–D15 specifies a digital channel as the data source waveform.
(MSO/MDO4000/B models only as well as MDO3000 and MDO400C models
with option MDO3MSO or MDO4MSO instal
led.)
BUS:B<x>:CAN:STANDard
Specifies the CAN bus standard to use.

Commands Listed in Alphabetical Order
Conditions
This feature re
quires installation of a DPO4AUTO or DPO4AUTOMAX
application module for MDO4000C models, or MDO3AUTO for MDO3000
models.

Bus
Syntax
BUS:B<x>:CAN:STANDard
BUS:B<x>:CAN:STANDard{CAN2X|CANFD} string
BUS:B<x>:CAN:STANDard?
Arguments
CAN2X sets the CAN bus standard to CAN 2.0
CANFD sets the CAN bus standard to CAN FD
Examples
BUS:B1:CAN:STANDard CANFD sets the CAN bus standard to CAN FD.
BUS:B1:CAN:STANDard? might return CAN2X, indicating that the CAN bus
standard is CAN 2.0.
BUS:B<x>:DISplay:FORMat
Specifies the display format for the numerical information in the bus waveform.
The display formats supported depend on the BUS:B<x>:TYPe.
