Overshoot+ Overshoot positive: Amount of
overshoot following a rising edge
specified as percentage of
amplitude.
(max. top)/ampl x 100 Waveform must contain
at least one rising
edge. On signals not
having two major levels
(triangle or saw-tooth
waves, for example),
may not give
predictable results.
Peak to peak Peak-to-peak: Difference
between highest and lowest
points in waveform. Unlike ampl,
does not assume the waveform
has two levels.
maximum minimum Gives a similar result
when applied to time
domain waveform or
histogram of data of the
same waveform. But
with histograms, result
may include
contributions from more
than one acquisition.
Period Period of a cyclic signal
measured as time between
every other pair of 50%
crossings. Starting with first
transition after left cursor, period
is measured for each transition
pair, with values averaged to
give final result.
Where: Mr is the
number of leading
edges found, Mf the
number of trailing
edges found,
the
time when rising edge i
crosses the x% level,
and
the time when
falling edge i crosses
the x% level.
