Select the desired scan function from the pull-down menu, as shown in the picture above.
To enable worst-case SOP optimization, click the “WSOP Enable” button at the bottom
left of the screen before running a scan. To disable it, select “Disable WSOP”. Please
note that this function can only be used with single-polarization signals.
Scan DGD only:
This function scans through a user-defined DGD range with a fixed SOPMD value.
Selection parameters:
Start DGD: DGD start value, in ps
Stop DGD: DGD end value, in ps
DGD step: step size in ps
Fixed SOPMD: fixed SOPMD value, in ps
2
Scan Interval (on top of graph): dwell time per point, in s. Minimum value: 0.4 s.
Note that the SOPMD value setting may limit the DGD scan range.
When the scan parameters are set, click “Start” to start the scan. As each point is
generated, the DGD, SOPMD, and output DOP are displayed above the graph, and the
output DOP vs. DGD is plotted in the graph on the left.
After the scan is finished, the data can be saved to a file by clicking “SAVE DATA”.
The program will prompt for a filename and location:
