The :BUS<n>:CAN commands are used to set relevant parameters for CAN decoding.
Command List:
 :BUS<n>:CAN:SOURce
 :BUS<n>:CAN:STYPe
 :BUS<n>:CAN:BAUD
 :BUS<n>:CAN:SPOint
:BUS<n>:CAN:SOURce
Syntax
:BUS<n>:CAN:SOURce <source>
:BUS<n>:CAN:SOURce?
Description
Sets or queries the source channel of CAN decoding.

CHANnel1
Return
Format
The query returns D0, D1, D2, D3, D4, D5, D6, D7, D8, D9, D10, D11, D12, D13, D14,
D15, CHAN1, CHAN2, CHAN3, or CHAN4.
Example
:BUS1:CAN:SOURce D0 /*Sets the source channel of CAN decoding to D0.*/
:BUS1:CAN:SOURce? /*The query returns D0.*/
:BUS<n>:CAN:STYPe
Syntax
:BUS<n>:CAN:STYPe <stype>
:BUS<n>:CAN:STYPe?
Description
Sets or queries the signal type of CAN decoding.

Discrete
{TX|RX|CANH|CANL|DIFFerential}
RX
Remarks
 TX: indicates the Transmit signal from the CAN bus transceiver.
 RX: indicates the Receive signal from the CAN bus transceiver.
 CANH: indicates the actual CAN_H differential bus signal.
 CANL: indicates the actual CAN_L differential bus signal.
 DIFFerential: indicates the CAN differential bus signal connected to an analog
channel by using a differential probe. Connect the differential probe's positive lead
to the CAN_H bus signal and connect the negative lead to the CAN_L bus signal.
Return
Format
The query returns TX, RX, CANH, CANL, or DIFF.
Example
:BUS1:CAN:STYPe TX /*Sets the signal type of CAN decoding to TX.*/
:BUS1:CAN:STYPe? /*The query returns TX.*/
