2.6 Operational Qualification
A summary of noise results is available in the OpQual (Operational Qualification) screens. This screen
gives specifications (for a given instrument configuration), the average of measured values, and an
indication of whether the result is valid for that configuration. The measured values are the average
result for 10 sets of scans, covering each wavelength region. Many users find this screen easier to
interpret, and more concise, than the tabulated data for each set of scans.
Operational Qualification Summary Screen: Noise Test
The OpQual2 tab contains summary information on wavelength accuracy and precision. For Model
5000 and 6500 instruments it also contains information on the bandwidth, as shown:
