Quick Noise Test - Agilent Technologies 1200 Infinity Series User Manual

Quick Noise Test

The quick noise test measures the noise of the detector, with Max-Light
Cartridge Cell or with Max-Light Cartridge Test Cell installed, in one minute
intervals over a total of 5 minutes.
The noise of the detector is calculated by using the maximum amplitude for all
random variations of the detector signal of frequencies greater than one cycle
per hour. The noise is determined for 5 one minute intervals and is based on
the accumulated peak-to-peak noise for the intervals. At least seven data
points per cycles are used in the calculation. The cycles in the noise
determination are not overlapping.
If the test is performed with the Max-Light Cartridge Test Cell, the test results
are not influenced by solvent or pump effects.
When In case of noise and drift problem.
