SOP:
The SOP operation screen includes the PMD-1000’s polarization control and scrambling
functions.
SCRAMBLING:
The PMD-1000 can perform either random scrambling, in which it generates random
discontinuous points on the Poincaré sphere, or continuous scrambling, in which it uses
an algorithm based on a set of triangle waves to generate a continuous trace on the
Poincaré sphere. Select the frequency for the desired scrambling mode (random or
triangle) and click the corresponding “Start” button to begin scrambling.
Frequency ranges:
Random scrambling: 1-6000 Hz
Triangle scrambling: 0.01-500 Hz
SET SOP:
Use this function to set and maintain a particular SOP. Set the Stokes parameters of the
desired state, making sure that they fulfill the condition
, and then click
the “Set” button to generate and maintain that state.

In most cases, as the user adjusts one Stokes parameter, the others will auto-adjust to
satisfy the normalization condition. However, if the user sets a condition that does not
satisfy the normalization condition, the program will display an error message:
