ID OR
The instrument triggers when the ID matches any of the patterns that you set in ID1 to ID4.
• Trigger Condition (Condition Setup)
On the Condition Setup screen, set the ID trigger conditions.
Break Synch
Triggers on a synch field that comes after a break field when the trigger condition is set to Break Synch only.
Break Synch of ID OR is always selected as a trigger condition.
ID
ID1 to ID4
IDs whose check boxes are selected are used as trigger conditions.
The ID trigger condition is met when the input signal ID bit pattern matches any of the specified ID bit
patterns. The method for setting the bit pattern of each ID is the same as with the ID/Data setting.
Source (Source)
Select the trigger source. After selecting the trigger source, configure the bit rate, sample point, HF rejection,
trigger level, hysteresis, and other settings.
Source (Source)
Set the trigger source to one of the settings below.
CH1 to CH4
Bit Rate (Bit Rate)
Select the LIN bus signal’s transfer rate from one of the settings below.
1200 bps, 2400 bps, 4800 bps, 9600 bps, 19200 bps, User Define
If you select User Define, set the transfer rate in the range of 1000 bps to 20000 bps in 10-bps steps.
Sample Point (Sample Point)
You can set the reference that will be used to determine the bus level in the range of 18.8 to 90.6% in 3.1%
steps.
The instrument’s LIN bus signal trigger circuit samples the input LIN bus signal using the internal clock and
detects the point of level change. Set the sample point as a percentage, with the detected point of change equal
to 0% and the point that is bit time after the point of change equal to 100%. The bit time is the inverse of the set
bit rate.
Level (Level), HF Rejection (HF Rejection)
Set these items for the trigger source.
These items are the same as those of the edge trigger.
Hysteresis (Hysteresis)
This item is the same as that of the CAN bus trigger.
