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 specified 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.

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.

Arguments
BINary – All values are displayed in binary.
HEXadecimal – All values are displayed in hexadecimal.
ASCII – All values are displayed in an ASCII format, for RS-232 only.
MIXed – Values are displayed in a mixture of hexadecimal, binary, and decimal,
depending on the field.
MIXED2 – Values are displayed in a mixture of hexadecimal, binary, decimal and
ASCII, depending on the field.
BLOCKHEX – Displays the 16-bits of each payload as a block of 4 hexadecimal
digits.
BUS:B<x>:DISplay:TYPe
Specifies the display type for bus. You can set up the bus to display the protocol
information, the logic waveforms that comprise the bus, or both.

Syntax
BUS:B<x>:DISplay:TYPe {BUS|BOTh}
BUS:B<x>:DISplay:TYPe?
Arguments
BUS displays the bus waveforms only.
BOTh displays both the bus and logic waveforms.
BUS:B<x>:ETHERnet:PRObe
This command specifies the Ethernet probe type: differential or single-ended. The
default is DIFFerential.
B<x> is the bus number 1-4. 1-3 for the MDO4000C and
1-2 for the MDO3000.
Conditions
This command requires a DPO4ENET application module for DPO/MSO4000B
and MDO4000/B/C models.
