Setting Up Drift Analysis Parameters

3. Under Default channel settings, define the following parameters as

needed:

³ Clear the Activate default channel selection, to use the currently

defined channel for analysis. This reduces the analysis time by

eliminating the peak detection over the complete spectral range.

The peaks outside the defined channel will not be detected or

analyzed.

³ Channel width (GHz or nm): indicates the limit inside which the

power values will be considered in the channel.

For default channels, the channel width that sets the limits of the

channel, should be the same as the channel distance or smaller

(channel distance is defined while creating a channel list). If the

channel width is not compatible with the channel spacing, either a

single peak may be found for two distinct channels and two

analysis would be performed and displayed for that peak, or, it is

possible that two peaks may be found within the same channel
