TRIGger:A:BUS
:B<x>:CAN:DATa:VALue
Arguments
<NR1> is a number specifying the data offset. It can be set to -1 to 7 for CAN 2.0
and-1to63forCANFD.Theserangesaremodifiedbythefollowing:
A value of -1 signifies “don’t care” and the instrument will match any byte value
that satisfy the match criteria.
A value of 0 signifies the start of the data field. If matching N bytes of data,
the system will only produce a match if the first N bytes of the data field satisfy
the match criteria.
The maximum is dependent on the number of bytes being matched and the CAN
standard selected. Its value is calculated as “[Absolute Maximum] – [Data Match
Size]”. For CAN 2.0, the absolute maximum is 8 bytes. For CAN FD, the absolute
maximum is 64 bytes. The minimum data match size is 1 byte, which produces
the ranges listed above. Increasing the data match size above 1 byte will adjust
the range of valid data offset values accordingly.
Trying to specify a data offset above the current maximum will result in the offset
being set to the current maximum.
Examples
TRIGger:A:BUS:B<x>:CAN:DATa:OFFSet 5 sets the CAN data offset to
5 bytes.
TRIGger:A:BUS:B<x>:CAN:DATa:OFFSet? might return 7, indicating that
CAN data offset is 7 bytes.
If the CAN standard is set for CAN 2.0 and the search data size is set to 3, the
maximum value for the data offset will be 5 (8 – 3 = 5).
If the CAN standard is set for CAN FD and the search data size is set to 8, the
maximum value for the data offset will be 56 (64 – 8 = 56).

a CAN bus signal. The trigger condition must be set to IDANDDATA OR DATA
(using TRIGger:A:BUS:B<x>:CAN:CONDition).
B<x> is the bus number (1-4).
1-3 for the MDO4000C and 1-2 for the MDO3000.
Conditions
This command requires a DPO4AUTO or DPO4AUTOMAX application module
on DPO/MSO4000B and MDO4000/B/C models and a
MDO3AUTO application
module on MDO3000 models.
