Source
Sets the source of the data line. All channel waveforms can be used.
If the MSO option R&S RTB-B1 is installed, you can use logic channels as source.
Remote command:
BUS<b>:CAN:DATA:SOURce on page 402
Threshold, Find Threshold
Set the signal threshold for the source channel. Enter a value, or use "Find Threshold"
to set the threshold to the middle reference level of the measured amplitude.
For analog channels, you can find the value also in the "Vertical" menu > "Chan-
nel <n>" >"Threshold"
For logic channels, you can find the value also in the "Logic" menu > "Threshold".
Remote command:
CHANnel<m>:THReshold on page 256

DIGital<m>:THReshold on page 432
Type
Selects the CAN-High or CAN-Low line. CAN uses both lines for differential signal
transmission.
If you measure with a differential probe, connect the probe to both CAN-H and CAN-L
lines and select "High".
If you use a single-ended probe, connect the probe to either CAN_L or CAN_H and
select "High" or "Low" accordingly.
Remote command:
BUS<b>:CAN:TYPE on page 402
Bit Rate
Sets the number of transmitted bits per second. The maximum bit rate for High Speed
CAN is 1 Mbit/s. The bit rate is uniform and fixed for a given CAN bus.
