Parameter Description Definition Notes
Local ttp Time between local feature trough
and the next local peak.
Hysteresis argument used to
discriminate levels from noise
in data.
Available with DDM2 option.
Standard in DDA-5005A.
Local tut Time a local feature spends under
a user specified percentage of its
peak-to-trough amplitude.
Hysteresis argument used to
discriminate levels from noise
in data.
Available with DDM2 option.
Standard in DDA-5005A.
Mathcad Produces a parameter using a
user-specified Mathcad function.
Available with XMAP and
XDEV option.
Standard in DDA-5005A.
Mathcad 2001i or later must
be loaded on the instrument.
MATLAB Produces a parameter using a
user-specified MATLAB function.
Available with XMAP and
XDEV option.
Standard in DDA-5005A,
WaveRunner 6000A,
WaveMaster, WavePro 7000A,
and sampling scopes
MATLAB must be loaded on
the instrument.
Maximum Measures highest point in
waveform. Unlike top, does not
assume waveform has two levels.
Highest value in
waveform between
cursors
Gives similar result when
applied to time domain
waveform or histogram of data
of same waveform. But with
histograms, result may include
contributions from more than
one acquisition. Computes
horizontal axis location of
rightmost non-zero bin of
histogram - not to be confused
with maxp.
Standard parameter.
Mean Average of data for time domain
waveform. Computed as centroid
of distribution for a histogram.
Average of data Gives similar result when
applied to time domain
waveform or histogram of data
of same waveform. But with
histograms, result may include
contributions from more than
one acquisition.
Standard parameter.
Median The average of base and top
values.
Average of Base and
Top.
Standard parameter.
