Setting the Averaging Time

The averaging time is the time the system spends on one specific point or

wavelength. You can either select one of the preprogrammed values or

specify the desired averaging time with the custom option.

Note: The stronger the signal, the faster a signal-to-noise ratio (SNR) will be

reached. If your signal is weak, increase the averaging time in order to

increase the accuracy of your results. Beyond a certain time limit, however,

the accuracy you gain will be insignificant.

To select a predefined averaging time:

On the Parameters tab, use the Averaging Time dial.

To set averaging time using custom option:

1. In the Parameters tab, set the Averaging Time dial to Custom.

2. Enter a value between 1.0 s and 60.0 s in the Avg Time box. The system

will warn you if the value exceeds those limits.

Note: The averaging time displayed on the screen does not take stabilizing time

into account. The Estimated Acq. Time box will give you an idea of the

overall time your acquisition will take, including the time needed for the

system to stabilize, as this time can vary.
