Feature Description
Data mode Y-axis format for acquired data.
For Abs*Factor, set Factor to a value by which to multiply measured
absorbance values.
Smooth Select the desired degree of smoothing (if available for the selected
data mode and Derivative setting). Smoothing reduces noise in the
data but can also remove some spectral features such as small peaks,
valleys and shoulders. For more information, see About Smoothing.
Derivative Select the desired derivative order for acquired data (if available for
the selected data mode).
Start wavelength
and End wavelength
Starting and ending values of the wavelength range for acquiring data.
Bandwidth A larger spectral bandwidth increases the amount of energy that
passes through the sample. Increasing the bandwidth can improve the
signal-to-noise ratio; however, a larger spectral bandwidth decreases
the ability to resolve closely spaced spectral features, especially in
scanning measurements.
Integration time How long the system acquires and averages data at each data interval.
Increasing the integration time improves the signal-to-noise ratio but
reduces the scan speed.
Data interval Difference in wavelength between two consecutive data points.
Scan speed Wavelength range covered per unit time. Varies inversely with
integration time. Increases as the data interval increases.
