A→B , Delay A→B , and Duty cycle.
Figure 4-22 shows a pulse with some of the time measurement points.
Figure 4-22
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.
Screen Duty: Defines as (the width of the positive pulse)/(Entire period)
Phase
: Compare the rising edge of CH1 and CH2, calculate phase difference of
two channels.
Phase difference=(Delay between channels at the rising edge÷Period)×360
°
.
Other measurements
+PulseCount : The number of positive pulses that rise above the mid
reference crossing in the waveform.
-PulseCount
: The number of negative pulses that fall below the mid
reference crossing in the waveform.
RiseEdgeCnt
: The number of positive transitions from the low reference
