Parameter Options Description
Sync Angle 0° to 359°
Unit: °
Phase lock angle
•
To activate this function, check the checkbox and input an azimuth.
•
At every full second, the lidar will rotate to that azimuthal position.

Lidar azimuthal position is defined in Section 1.2 Basic structure.

Definition of the full second (detailed in Section B.1 Source of absolute time):
•
When GPS is locked, the full second is defined as the rising edge of the GPS
PPS signal.
•
When PTP is tracking or locked, the full second is retrieved from the PTP
master clock.
•
When neither GPS nor PTP is locked, the full second is defined as the rising
edge of the lidar's internal 1 Hz signal.
To phase-lock multiple lidar units, connect them to the same clock source and set the
same sync angle. These lidar units will rotate to the same azimuthal position at every full
second.
Trigger Method Time-Based (default)
Angle-Based
The way laser firings are triggered.
Angle-based Lasers fire every 0.2° at 10 Hz or 0.4° at 20 Hz.
Time-based Lasers fire every 55.56 μs.
Noise Filtering OFF (default)
ON
To reduce the scattered false positives (i.e. noise points) in point cloud data.
