10.4. The automatic measurement of time parameters
The
PeakTech
®
oscilloscopes provides time parameters auto-measurements include Frequency,
Period, Rise Time, Fall Time, +Width, -Width, +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.
+Duty
: +Duty Cycle, defined as +Width/Period.
-Duty
: -Duty Cycle, defined as -Width/Period
.

Description
Sampling
Normal sampling mode
Peak Detect
Use to capture maximal and minimal samples. Finding highest and
lowest points over adjacent intervals. It is used for the detection of the
jamming burr and the possibility of reducing the confusion.
Average
It is used to reduce the random and don´t-care noises, with the editable
number (1
≤ number ≤ 128) of averages.
