FlexRay Decoding (Option)
FlexRay is a type of differential serial bus configured with three consecutive
segments (i.g. header, payload, and trailer). The oscilloscope samples the FlexRay
signal at the specified sample position and judges each data point as logic "1" or
logic "0" according to the preset threshold level. The FlexRay decoding is required to
specify the signal type and baud rate.
In the decode setting menu, press Decode1

Bus Type , then rotate the
multifunction knob to select "FlexRay". Press down the knob to select it. You can
also press Bus Type continuously or enable the touch screen to select it.
1. Enable or disable the bus

automatically). For analog channels, the threshold level settings will also be
copied.
3. Set the source and the threshold

Press Source and rotate the multifunction knob to select the desired
source channel, and then press down the knob to select it. You can also
press Source continuously or enable the touch screen to select it. The
available channels include CH1-CH4 and D0-D15.

When you select the analog channel (CH1-CH4), press Threshold , then
rotate the multifunction knob or use the pop-up numeric keypad to set
the threshold of the source channel. When you modify the threshold of the
channel, a dotted line displaying the current threshold level is displayed on
the screen. The dotted line disappears in about 2 s after you stop modifying
the threshold.
4. Signal setting
Press Settings to enter the signal setting menu.

Channel selection
Press Channel continuously to select a channel ("A" or "B") that matches
the actual FlexRay bus signal.

Specify the signal rate
Press Baud to open the baud rate list (2.5 Mbps, 5 Mbps, and 10 Mbps),
and select a preset baud rate that matches the actual FlexRay bus signal.
You can also press Baud continuously, then rotate the multifunction knob
at a small step value or use the pop-up numeric keypad to set the
