Waveform Measurements
Standard Waveform Denitions
Overshoot Overshoot is a distortion which follows a major transition.
If rst edge is rising,
overshoot = local max 0 top
Else,
overshoot = base 0 local min
Preshoot Preshoot is a distortion which precedes a major transition.
If rst edge is falling,
preshoot
=
base
0
local
min
Else
,
preshoot
= local
max
0
top
The
instrument computes
a
local
minimum
and
maximum
when
computing
preshoot
and overshoot.
The
local
minimum
or
maximum
occurs
before
the
rst
transition
in
the
case
of
preshoot
or
in
the rst
50
percent
of
the
time
dened
along
the
threshold
in
the
case
of
overshoot.
This makes
windowing
less
critical
for
these
measurements
