25 CAN Triggering and Serial Decode
6 Press the Signals softkey to open the CAN Signals menu.
7 Press Source; then, select the channel for the CAN signal.
The label for the CAN source channel is automatically set.
8 Press the Threshold softkey; then, turn the Entry knob to
select the CAN signal threshold voltage level.
The threshold voltage level is used in decoding, and it will
become the trigger level when the trigger type is set to the
selected serial decode slot.
9 Press the Baud softkey; then, turn the Entry knob to select the
baud rate that matches match your CAN bus signal.
The CAN baud rate can be set to predefined baud rates from
10 kb/s up to 5 Mb/s or a user-defined baud rate from
10.0 kb/s to 4 Mb/s in increments of 100 b/s. Fractional
user-defined baud rates between 4 Mb/s and 5 Mb/s are not
allowed.
The default baud rate is 125 kb/s
If none of the pre-defined selections match your CAN bus signal, select User
Defined; then, press the User Baud softkey and turn the Entry knob to enter the
baud rate.
10 Press the Sample Point softkey; then, turn the Entry knob to select the point
between phase segments 1 and 2 where the state of the bus is measured. This
controls the point within the bit's time where the bit value is captured.
11 Press the Signal softkey and select the type and polarity of the CAN signal. This
also automatically sets the channel label for the source channel.
