Chapter 8 Protocol Decoding RIGOL

CAN Decoding (Option)
You need to specify the CAN signal type and sample position for CAN decoding. The
oscilloscope samples the CAN signal on the specified sample position.
Press Decode1 Decode and select “CAN” to open the CAN decoding function
menu.
If the current trigger type of the trigger system is CAN, pressing CopyTrig softkey
can copy the current CAN trigger settings (include the source channel, signal type,
baud rate, sample position and so on) and apply them to the CAN decoding function.
Then, if needed, you can still set the CAN decoding parameters according to the
introductions below.
Note: The copy function is only available when the current trigger type is “CAN”;
otherwise, CopyTrig is not available.
1. Source
Press Source and select any channel (CH1, CH2 or any channel of D0-D15) as
the source channel.
If the source channel is set to CH1 or CH2, you can set the threshold of the
corresponding analog channel. Press Threshold to open the threshold setting
menu. Then, press TTL, CMOS or ECL to set the threshold of the specified
channel to the corresponding level value; or press Threshold and use to set
the threshold. The settable range is from (-5*vertical scale - vertical position) to
(5*vertical scale - vertical position). The default is 0 V. Pressing down
can
quickly reset the threshold level to 0 V.
Note: When the threshold selected is beyond the specified range, it will be
automatically limited within the range.
If the data channel is set to any channel of D0-D15, Threshold will be hidden
automatically.
2. Signal Type
Press Signal Type to select the desired signal type.
Rx: the received signal from the CAN signal line.
Tx: the sending signal from the CAN signal line.
