What does gain do?
Gain amplifies the detector signal intensity, making it larger relative
to the level of electronic noise. This is helpful when the signal is
weak, such as when you use some sampling accessories. You can let
OMNIC automatically adjust the gain to maximize the signal by
setting the Gain parameter to Autogain. We recommend using this
setting to ensure the best spectral quality.
In OMNIC Help Topics find “gain” in the Index and go to “Setting
the gain.”
When should I save interferograms with my spectra?
Save interferograms if you think you may want to restore the
original data after it has been processed or if you want to keep an
archive of the original data.
In OMNIC Help Topics find “saving, interferograms” in the Index
and go to “File handling.”
What does the Collect Sample window show?
The window displays the “live” spectrum as it is being collected plus
a gauge indicating the progress of the collection, an indicator
showing whether any problems have occurred and other information
about the collection.
In OMNIC Help Topics find “spectrum” in the Index and go to
“Collecting a sample spectrum.”
