5
Fix the optical fiber at the input of the FP-Etalon; allow the FP-Etalon to
stabilize for at least 5 minutes.
6 To configure the instruments in all of the subsequent measurements
follow the settings reported below - except if otherwise specified:
a ensure the modulation of the source is turned off
b Set the power and sweep settings:
7 Before taking the measurement:
a perform a lambda zero (via menu) on the TLS module;
b zero the power-meter (make sure the TLS output is disabled).
Reference Scans These scans are executed in stepped mode, one per wavelength range,
and will provide the reference wavelength measurements (once the
threshold-crossing analysis is performed).
