2.6 Spectrum Control Options

The spectrum analyser three parameters that control the quality of the Spectra:
• Smoothing,
• Averaging, and
• Integration Time.
To access this option navigate to the Configuration Options tab, click the Schedule
button and select the Spectrometer Settings tab on the Schedule Configuration
window, see Figure 14.

2.6.1 Spectrum Smoothing

Smoothing specifies the number of readings on either side of a particular reading to average
across an entire spectral acquisition. This method averages a group of adjacent detector
elements. A value of three, for example, averages each data point with three points (or bins) to
its left and three points to its right.
The greater this value, the smoother the data and the higher the signal-to-noise ratio. However,
if the value entered is too high, a loss in spectral resolution results.

2.6.2 Spectrum Averaging

Smoothing specifies the number of spectra to average for the specified spectra output. A higher
value for this parameter provides a better signal-to-noise (S:N) ratio.
