two input waveforms.
Standard in
DDA-5005A.
Peaks Number of peaks in a
histogram. Available with DDM2,
JTA2, and XMAP
options.
Standard in
DDA-5005A.
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.
Standard parameter.
Percentile Horizontal data value that
divides a histogram so the
population to the left is xx%
of the total. Available with DDM2,
JTA2, and XMAP
options.
Standard in
DDA-5005A.
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.
Standard parameter.
