Description of the GUI
1.
Tabs selection:
•
“Spectrum” tab: This tab is used to set acquisition parameters and display spectral data.
•
“Interferogram & PSD” tab: This tab displays the measured interferogram and its
corresponding Power Spectral Density (PSD)
2.
Measurements Parameters area:
•
Scan Time: User can specify the Scan Time for the measurements.
•
Resolution: User can select between different pre-set resolution values.
•
Optical Gain Settings: User can select the optical gain for different measurement types
(Absorbance/Transmission or Reflection). The X button allows deleting a gain setting
selected in the dropdown menu.
•
Run Mode:
i.
Single: Display the data for a single measurement at the specified scan time.
ii.
Cont.: Take continuous consecutive measurements at the specified scan time.
•
Command buttons:
i.
Spectrum tab:
1.
Background: Initiate the background measurement. No material should be present in the light path
during this measurement. For the best measurement results, background measurements should be
taken as frequently as possible. A new background measurement must be taken when any
measurement parameter is changed (e.g., Resolution, Optical Gain Settings, etc.).
2.
Run: Initiates the spectrum measurement for the sample placed in the light path. The background-
corrected spectrum is automatically calculated and displayed.
3.
Stop: Cancels the current measurement in progress.
