It can be synchronized to control 4 servos and used to compare the performance of steering gear control. The steering servo output signal can be accurate to 2µs (1 millisecond = 1000 microseconds). You can test whether the steering gear is able to respond to subtle changes.
With the PPM signal test function in the display, the input PPM signal changes while the input PPM signal synchronizes the output to the servo.
It automatically enters manual mode (Manual) at 20µs.
The 50Hz analog servo signal cycle has a frequency of 50Hz. Use the rotary potentiometer to decrease or increase the width of the output pulse.

Button Select (Note: the key switch function, circulation patterns)
