Set the trigger on the rise of input signal
to measure the jitter of the rise of output
Set the trigger on the fall of input signal
to measure the jitter of the fall of output
Notes ( 1) The waveform write time shall be 4 seconds. But do not allow the waveform to be distorted by increasing the
brightness too much.
( 2) V_CC = 3.0 ±0.05V (State of operating)
( 3) The probe for the oscilloscope must be more than 1MΩ and less than 10pF.
