INTERVAL:
This option sets the dwell time per point, in ms. Use the left and right arrows
to move between digits and the up and down arrows to increment the selected
digit. Note that a particular memory bank can store discrete mode PMD states,
continuous mode PMD states, or a mixture of the two. If the memory bank
contains only discrete mode values or only continuous mode values, the dwell
time range is 1 to 60,000 ms. If the memory bank contains both discrete and
continuous mode PMD values, the minimum dwell time is 100 ms. The
ENTER key selects the displayed value.
f.
CYCLES:
This option sets the number of times to run the scan. The cycle range is
1-9999. Use the left and right arrows to move between digits and the up and
down arrows to increment the selected digit. The ENTER key sets the number
of cycles to the displayed value.
4.2.4 SOP:
Pressing the SOP key accesses the PMDPro’s deterministic polarization control and
scrambling functions, including generation and stabilization of a single SOP, specified
via Stokes parameters; continuous or random scrambling; or generation of specified
traces.
If the PMDPro’s PMD generator is set for a static PMD value (i.e. not scanning), that
PMD setting will be unchanged during any polarization control accessed through the SOP
menu.
For deterministic polarization control, the input polarimeter is used to generate the
feedback signal to control the polarization controller, so the generated SOP is the SOP of
the light before it enters the PMD element.
When the SOP key is pressed, the LCD displays 5 menu options on 3 screens:
