10.4. The automatic measurement of time parameters
The
PeakTech
®
oscilloscopes provide time parameters auto-
measurements
include
Frequency, Period, Rise Time, Fall Time, +Width, -Width, Delay
1→2
, Delay
1→2
,
+Duty and
–Duty.
Figure shows a pulse with some of the time measurement points.
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
.
