Arguments
<NR1> is an integer whose minimum and default values are -1 (don't care) and
maximum is up to 7 (for C AN 2.0) or up to 63 (for ISO CAN FD and Non-ISO
CAN FD). The maximum is d ependent on the number of bytes being m atched
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 ISO CAN
FD and Non-ISO 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.
Examples
SEARCH:SEARCH1:TRIGGER:A:B US:CAN:DATA:OFFSET 5sets the CAN data
offset to 5 bytes.
SEARCH:SEARCH1:TRIGGER:A:B US:CAN:DATA:OFFSET? might return 7,
indicating the 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 ISO CAN FD or Non-ISO CAN FD
and the search data size is set to 8, the maximum value for the data offset will be
56 (64 - 8 = 56).
SEARCH:SEARCH<x>:TRIGger:A:BUS:CAN:DATa:QUALifier
This command sets or queries the CAN bus trigger data qualifier to be used when
searching on a CAN bus signal. The search number is specified by <x>.
