Suggested
Method
Noise Filter Specify a Correlation Factor of 0 to 1.0.
(NF)
Settings from 0.5 to 0.7 yield acceptable
results for most data. A setting close to 1.0
yields a higher degree of noise reduction.
(May affect
peak If applying the Noise Filter with a certain
resolution.) Correlation Factor does not yield the
necessary noise removal, return to the original
trace (see "Returning to the original trace" on
page 4-4) and apply the Noise Filter again with
a higher Correlation Factor setting. Applying
the filter more than one time with the same
Correlation Factor setting does not improve
noise removal.
Gaussian Specify a Filter Width in data points (odd
Smooth integers only). The maximum number of
(SM) smoothing points is 2001. Points less than 1
Filter Width from the edge of the spectrum are
not smoothed.
(May affect
peak
resolution.)
