Procedure
1 Turn on the lasers and allow them to warm up.
2 Set the polarization controller to a scan rate of 5.
3 On the Agilent 86120B, press the Preset key.
4 Connect the laser's optical output to the polarization controller's optical input.
5 Connect the polarization controller's optical output to the Agilent 86120B
6 Set the polarization controller to autoscan.
7 On the Agilent 86120B, press Peak WL, Appl's, and then DRIFT. Press MAX-MIN so
8 Wait five minutes, read the peak amplitude drift from the Agilent 86120B, and

Test 3. Polarization Dependence

Polarization Dependence is verified using the following devices:
Do not exceed +18 dBm source power. The Agilent 86120B's input circuitry can
be damaged when total input power exceeds 18 dBm.
Perform the following procedure first using the 1310 nm laser and then repeat
the steps using the 1550 nm laser.
