Byte Offset
The setting is available in CAN FD option R&S RTH-K9.
Sets the byte offset, that defines the strat position of the data for the data pattern com-
parison.
Remote command:
TRIGger:CAN:FDATa:DPOSition on page 462
Address from Label
If a label list with node names was loaded and applied in the bus configuration, you
can select the node name from the list instead of entering the numeric identifier.
The instrument triggers on the identifier of the selected node.
Error conditions: CRC, Bit stuffing, Form, Ack, SC
If a CAN detects a bit stuffing error, form error, or Ack error, it transmits an error flag at
the next bit. The R&S RTH detects errors in the message and triggers on these errors
even if no CAN node sends an error flag.
●
CRC error
CAN uses the cyclic redundancy check (CRC), which is a complex checksum cal-
culation method. The transmitter calculates the CRC and sends the result in the
CRC sequence. The receiver calculates the CRC in the same way. A CRC error
occurs when the calculated result differs from the received value in the CRC
sequence.
●
Bit stuffing error
The frame segments Start Of Frame, Arbitration Field, Control Field, Data Field
and CRC Sequence are coded by the bit stuffing method. The transmitter automati-
cally inserts a complementary bit into the bit stream when it detects five consecu-
tive bits of identical value in the bit stream to be transmitted. A stuff error occurs
when the 6th consecutive equal bit level in the mentioned fields is detected.
●
Form error
A form error occurs when a fixed-form bit field contains one or more illegal bits.
●
Ack error
An acknowledgement error occurs when the transmitter does not receive an
acknowledgment - a dominant bit during the Ack slot.
●
SC errror
A stuff count (SC) error occurs if th received stuff count value does not match the
value calculated from the own stuff bit count.
Only relevant for CAN FD signals in ISO standard.
