I-OSNR Range (only valid for OSA-500R and OSA-110R)
This parameter defines the resolution of the polarization nulling routine for true in-band
OSNR measurement.

Module is used to analyze results from an EDFA. EDFA results
are displayed in the results table. (See
on page 279)
Module is used to analyze results from a DFB. DFB results are
displayed in the results table (See
page 281).
Module is used to analyze results from a Fabriperot Laser. FPL
results are displayed in the results table.
Module is used to analyze results from a LED. LED results are
displayed in the results table.
The OSA sweeps continuously and displays the results
The OSA performs one single sweep and displays the result
The OSA calculates a statistic of a number of sweeps. The
number of sweeps must be entered (next parameter).
Set the OSA filter to certain wavelength and switch the output of
the filter to output connector. (OSA-501M only)
The OSA measures power, wavelength and signal to noise ratio
over time. The number of sweeps and the wait time between the
sweeps need to be set.
NOTE
For Drift measurements a Grid needs to be defined and the Channel
Detection parameter is set to Grid.
