- CAN_L: indicates the actual CAN_L bus signal.
- Rx: indicates the Receive signal from the CAN bus transceiver.
- Tx: indicates the Transmit signal from the CAN bus transceiver.
- DIFF: indicates the CAN differential bus signals connected to an analog
channel by using a differential probe. Connect the differential probe's
positive lead to the CAN_H bus signal and connect the negative lead to the
CAN_L bus signal.
- Specify the standard signal rate
Three methods are available for setting the baud rate:
- Press Baud, then set the user-defined baud rate with the displayed numeric
keypad.
- Press Baud to select the preset baud rate. The available baud rates include
10 kbps, 20 kbps, 33.3 kbps, 50 kbps, and etc.
- Press
Baud, then rotate the multifunction knob to adjust the baud rate at
a small step.
- Sample position
Sample position is a point within a bit’s time. The oscilloscope samples the bit
level at this point. The sample position is represented by the proportion of "the
time from the start of the bit to the sample point" to the "bit time", as shown in
the figure below.
One Bit
60%
70%
80%
Figure 15.10 Sample Position
Press
Sample Position, then rotate the multifunction knob or use the pop-
up numeric keypad to set the sample position. The settable range is from 10%
to 90%.
