Features：
Test Together: can be synchronized output control 4 servos.
Accurate Test: used to compare the performance steering gear control of the steering servo output signal can be accurate to 2us
(1 milliseconds = 1000 microseconds), you can test the steering gear is able to respond to subtle changes.
PPM Signal: with PPM signal test function in the display, the input PPM signal changes while the input the PPM signal
