A→B , Delay A→B , and Duty cycle.
Figure 5-72 shows a pulse with some of the time measurement points.
Figure 5-72
Rise Time: Time that the leading edge of the first pulse in the waveform takes to
rise from 10% to 90% of its amplitude.
Fall Time: Time that the falling edge of the first pulse in the waveform takes to
fall from 90% to 10% of its amplitude.
+D width: The width of the first positive pulse in 50% amplitude points.
-D width: The width of the first negative pulse in the 50% amplitude points.
+Duty: +Duty Cycle, defined as +Width/Period.
-Duty:-Duty Cycle, defined as -Width/Period.
Delay A→B : The delay between the two channels at the rising edge.
Delay A→B : The delay between the two channels at the falling edge.
Duty cycle: Defines as (the width of the positive pulse)/(Entire period)
The phase difference of two channels:
Phase: Compare the rising edge of CH1 and CH2, calculate phase difference of
two channels.
Phase difference =[ (Delay between channels at the rising edge)*PI]/Period.
