52 Agilent 81560A, 81561A, 81566A, & 81567A Optical Attenuator Modules, First Edition
Polarization.
Measure the Reference Power.
17 Keep the settings from the polarizer and the l/4 and l/2 Retarder
Plates from steps 8, 10 and 12 for Linear Horizontal polarized light.
18 Note the power reading as Reference Power P1 in the Test Record.
19 Set the l/4 and l/2 Retarder Plates to the corrected wavelength
dependent positions for Linear Vertical polarized light.
20 Read the power on the power meter and note is as Reference Power
P2 in the Test Record.
21 Set the l/4 and l/2 Retarder Plates to the corrected wavelength
dependent positions for Linear Diagonal polarized light.
22 Note the power reading as Reference Power P3 in the Test Record.
23 Set the l/4 and l/2 Retarder Plates to the corrected wavelength
dependent positions for Right Hand Circular polarized light.
24 Note the power reading as Reference Power P4 in the Test Record.
25 Connect the equipment as shown in Figure 16.
