Setting Up the Instrument in Drift Mode
Optical Spectrum Analyzer 139
Setting Up Drift Analysis Parameters
³ Stop range (nm or Thz): indicates the ending range of the
channel list.
³ Channel center wavelength/frequency: indicates the spectral
center-of-mass for the peak in that channel.
Note: When using the custom channel center wavelength option, the first channel
will be centered at the Start Range, and the list will be created using
channel distance and channel width.
³ Channel distance (nm or GHz): indicates distance between the
channels. The value of channel distance will be set depending on
the selection made for the channel center wavelength option. The
channel distance box will be enabled only when the channel
center wavelength option is set to custom.
³ Channel width (nm or GHz): indicates the limit inside which the
power values will be considered in the channel. Integrated power
is calculated on channel width.
³ Name prefix: Adds prefix to the channel names.
³ Starting Value: Sets the increment starting value for the channel
name in the channel list.
³ Increment value: Sets the increment value for the channel name
in the channel list.
