Set the polarity of chip selection enable signal to positive or negative.
a.
Positive polarity: It is 1 when the setting signal is greater than threshold. Otherwise, it is 0.
b.
Negative polarity: It is 1 when the setting signal is less than threshold. Otherwise, it is 0.
(8)
SCLK Polarity
Set the edge of clock signal to rising edge or falling edge.
a.
Rising edge: It will be generated on the rising edge of clock signal.
b.
Falling edge: It will be generated on the falling edge of clock signal.
(9)
Data Polarity
Set the polarity of data signal MOSI to positive or negative.
a.
Positive polarity: It is 1 when the setting signal is greater than threshold. Otherwise, it is 0.
b.
Negative polarity: It is 1 when the setting signal is less than threshold. Otherwise, it is 0.

Information Source
Set CAN protocol trigger source, which can be CH1, CH2, CH3, CH4 or D0-D15. The current selected
source will displayed on the right corner of the screen. The source supports display and select digital
channel only the digital channel is opened in LA.
Note
: Only the channel that has been connected to the signal, select it as the trigger source that can
get the stable trigger and correct decoding.
(3)
Signal Type
Set the input signal of the current source is high data line signal or low data line signal, which can select
CAN_H or CAN_L.
(4)
Bit Rate
（
bps
）
Set the bit rate of CAN bus serial data, which can select 10 k, 20 k, 25 k, 31.25 k, 33.3 k, 37 k, 50 k, 62.5 k,
68.266 k, 83.3 k, 92.238 k, 100 k, 125 k, 153 k, 250 k, 400 k, 500 k, 800 k, 1 M or user-defined. User can input
customized bit rate when “user-defined” is selected.
