PMIN PIT MINIMUM
Description
Pit Minimum provides a measurement of the minimum voltage value of pits of interest, and a
comparison of how the minimum point in the waveform corresponds to the ptop value. When
pmin
is configured as a custom parameter, all minimums within the single nT or range of nT are
calculated. Histogramming or trending such a configuration would result in one value per pit in the
nT range contributing a value to the histogram or trend. The value displayed on the custom
parameter display line is the average of all such minimum calculations. ‘nT Table’ mode provides
an average minimum value for the pits in each n index.
Display Options
ORM parameter calculations can be displayed, histogrammed, and trended in a variety of ways.
DISPLAY TYPE VALUE DISPLAYED
Parameter Statistics Off
All values of the minimum for all pits within the selected ‘nT’
range for the last acquisition.
Parameter Statistics On
Average, minimum, maximum, and sigma of the minimum for
all pits that are within the selected ‘nT’ range for all acquisitions
since the last C
LEAR S WEEPS operation.
nT Table
List of values of the average minimum for each group of pits of
common ‘nT’ width for the last acquisition.
Histogram Function
Histogram graph of the value of the minimum for all pits within
the selected ‘nT’ range for all acquisitions since the last C
LEAR
S WEEPS operation.
Trend Function
Trend graph of the value of the minimum calculated for each
pit that is within the selected ‘nT’ range for all acquisitions
since the last C
LEAR S WEEPS operation.
