Figure 5-54 shows a pulse with some of the time measurement points.
Figure 5-69
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.
+Width: The width of the first positive pulse in 50% amplitude points.
-Width: The width of the first negative pulse in the 50% amplitude points.
Delay 1→2 : The delay between the two channels at the rising edge.
Delay 1→2 : The delay between the two channels at the falling edge.
+Duty: +Duty Cycle, defined as +Width/Period.
-Duty:-Duty Cycle, defined as -Width/Period.
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.
How to Measure with Cursors
Press the Cursor button to display the cursor measurement function menu (CURS
MEAS) in the screen.
The Cursor Measurement for normal mode:
The cursor measurement includes Voltage Measurement and Time Measurement
at normal mode, shown as Figure 5-52.
