shows a pulse with some of the time measurement points.
Figure 4-15
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
value to the high reference value in the waveform.
