8.5 CAN (Option R&S RTH-K3)
CAN is the Controller Area Network, a bus system used within automotive network
architecture.
8.5.1 CAN Configuration Settings
Access: "Bus" menu > "Bus Protocol" = "CAN" > "Config"
Source
Sets the input channel of the CAN line. All active analog channels can be used.
If option R&S RTH-B1 is installed, digital channels can also be used as source.
Remote command:
BUS:CAN:DATA:SOURce on page 399
Polarity
Selects whether the chip select signal is high active (high = 1) or low active (low = 1).
Remote command:
BUS:CAN:TYPE on page 400
Threshold, Technology, Find Level
Sets the threshold value for digitization of signals. If the signal value is higher than the
threshold, the signal state is high. Otherwise, the signal state is considered low.
You can select the threshold voltage on the source CAN for various types of integrated
circuits in the "Technology" list, or set a user-defined value in "Threshold". You can
also let the instrument set the appropriate threshold using "Find Level".
Changing the thresholds in the bus configuration changes also the thresholds of ana-
log channels in the "Vertical" menu, or the thresholds of logic channels in the "Logic"
menu.
