Use the up and down arrow keys to move between menu options and the ENTER key (the
center key in the arrow keypad) to select the desired option.
1.
SCRAMBLING:
This option enables the random or continuous (triangle wave based) scrambling
functions of the PMDPro. Selecting this option brings up the following screen:
Selecting RANDOM SCRAMBLE brings up the following screen:
Selecting TRIANGLE SCRAMBLE brings up the following screen:
For either scrambling mode, the top line shows the selected scrambling mode and
frequency, and the bottom line shows the current DGD and SOPMD.
Select the desired scrambling frequency. Use the left and right arrows to move
between digits and the up and down arrows to increment the values. The
scrambling frequency range is 1-6000 Hz for random scrambling and 0.01-500 Hz
for triangle scrambling. When the desired frequency is set, press the ENTER
button. The PMDPro will begin scrambling. The screen display remains the same,
but the cursor will move to the bottom right corner of the screen. During
scrambling, pressing the left arrow key will stop the scrambling and move the
cursor to frequency selection so that the scrambling frequency can be changed.
2.
SET SOP:
This option generates and maintains a user-set state of polarization (SOP) against
fluctuations in input polarization state. The desired polarization state is set via
Stokes parameters. When this option is selected, the LCD displays the following
screen:
Use the left and right arrow keys to move to the first Stokes parameter to be set.
Set the value for the first parameter and then press ENTER. The cursor will
advance to the next Stokes parameter. Use the arrow keys to set the desired value
