Description
Specifies Scan or Fixed data acquisition.
Y-axis format for acquired data.
Starting and ending values of the wavelength range for acquiring
data.
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.
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.
Wavelength range covered per unit time. Varies inversely with
integration time. Increases as the data interval increases.
Estimated duration of data acquisition. Increases as integration
time increases and as the data interval decreases. Varies inversely
with scan speed.
Shows the analysis wavelength(s) entered on the Measurement
tab.
