Feature Description
Mode Specifies Scan or Fixed data acquisition.
Data mode Y-axis format for acquired data.
Start wavelength and End
wavelength (Scan only)
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.
Integration time How long the system acquires and averages data at each data
interval (for scanning measurements) or at each measured
wavelength (for fixed-wavelength measurements). Increasing the
integration time improves the signal-to-noise ratio but reduces
the scan speed.
Data interval (Scan only) Difference in wavelength between two consecutive data points.
Scan speed (Scan only) Wavelength range covered per unit time. Varies inversely with
integration time. Increases as the data interval increases.
Estimated time (Scan
only)
Estimated duration of data acquisition. Increases as integration
time increases and as the data interval decreases. Varies inversely
with scan speed.
