Noise Summary displayed using the OpQual tab.
The OpQual tab brings up the display shown. This shows results of the Noise Test for each of the four
wavelength regions. These regions are:
• 400-700nm
• 700-1100nm
• 1100-1700nm
• 1700-2500nm
For each region, results are given for
• Peak-to-Peak Noise (P-P)
• Root-Mean-Square Noise (RMS)
• Bias (A measure of baseline energy changes)
Each of these parameters is described in more detail in the Diagnostics Section of the Vision Manual.
If the test is reported as “Passed” the user may proceed with sample analysis.
