Smooth - Agilent Technologies 86038B User Manual

GD Options Area
Show DGD Contribution Displays error bars on the group delay
trace to show how much the GD varies due to polarization
dependence. This option only applies when DGD data exists.
Refer to "CD/PMD" on page 104.
CD Options Area
Dispersion coefficient (ps/nm-km) Dispersion coefficient can be
displayed if the device length has been measured or specified
(See "Length'). If this option is enabled, each value in the CD
trace is divided by the device length (km) to yield the CD
coefficient.
GD Source By default, the CD trace is calculated using the
slope of the actual GD trace. If a GD trace has been smoothed or
curve fitted, selecting that trace as the GD Source may provide a
lower noise CD trace.
Gain Options Area
Show PDL Contribution
Adds display of maximum and
minimum Gain/Loss traces, with respect to polarization state, if
PDL data exists.
Attenuation Coeff. (dB/km) The attenuation coefficient can be
displayed if the device length has been measured or specified
(See "Length''). If this option is enabled, each value in the
Gain/Loss trace is divided by the device length (km) to yield the
attenuation coefficient.

Smooth

Smoothing performs the selected type of averaging of
neighboring wavelength points to reduce the noise without
losing too much detail. The smoothed trace takes over the
current trace color and the unsmoothed (raw) trace is shown in
gray.
Enable Smoothing
When selected, smoothing is turned on.
