"Non-ISO"
Signals are decoded according to the the Bosch CAN FD protocol.
"ISO"
Signals are decoded according to the the ISO CAN FD protocol. This
protocol has an additional stuff count field before the CRC sequence.
Remote command:
BUS<m>:CAN:FDATa:PSTandard on page 1489
Threshold
Sets the threshold value for digitization of the signal. If the signal value on the line is
higher than the threshold, the signal state is high (1 or true for the boolean logic). Oth-
erwise, the signal state is considered low (0 or false).
There are several ways to set the threshold:
●
"Threshold"
Enter the value directly in the field.
●
"Full autoset"
Starts software algorithms for determining the signal threshold levels and bitrate.
●
"Auto thresholds"
Executes the measurement of reference levels and sets the thresholds to the mid-
dle reference level of the measured amplitude.
●
"Preset thresholds"
Selects the default threshold voltage for various signal technologies from a list. The
value is set to "Manual" if the threshold was set with "Auto threshold", or was
entered directly.
Note: If the sources are digital channels, the same threshold values are used for the
parallel and the serial buses. You can set the thresholds either in the parallel bus con-
figuration or in the serial bus configuration.

Bit rate (CAN) / Arbitration rate (CAN FD)
For CAN buses, the "Bit rate" sets the number of transmitted bits per second.
For CAN FD buses, this parameter is called "Arbitration rate" and sets the bit rate of
the arbitration phase.
The maximum value of this rate is 1 Mbit/s. The bit rate is uniform and fixed for a given
CAN or CAN FD bus.
To select a bit rate from the list of predefined values, tap the button beside the field. To
enter a specific value, open the keypad. The list of predefined values is also available
in the keypad.
Remote command:

Data rate
The setting is available in CAN FD option R&S RTE-K9.
