Figure 5 shows the PMD states covered by the PMDPro’s discrete and continuous PMD
generation modes.

Pressing the PMDE key on the front panel accesses the PMDPro’s DGD/PMD generation
functions, including generation of a single DGD/SOPMD pair, scanning through DGD or
PMD states in the lookup table, generating a continuous PMD trace, scanning through a
user-generated sequence of states, or generation of a Maxwellian distribution of DGD
values.
