Scan DGD and SOPMD:
This function performs a 2-D DGD/SOPMD grid scan over a user-defined area.
Selection parameters:
Start DGD: DGD start value, in ps
Stop DGD: DGD end value, in ps
DGD step: DGD step size, in ps
Start SOPMD: SOPMD start value, in ps
2
Stop SOPMD: SOPMD end value, in ps
2
SOPMD step: SOPMD step size, in ps
2
Scan Interval (on top of graph): dwell time per point, in s. Minimum value: 0.4 s.
When the scan parameters are set, click “Start” to start the scan. At each point in the scan,
the DGD, SOPMD, and maximum output DOP for that point are displayed above the
graphs, and the maximum output DOP vs. DGD is plotted in the graph on the left. The
maximum output DOP for the scan and the corresponding DGD and SOPMD values are
displayed below the graph. The graph on the right is a 3D graph of DOP vs. SOPMD and
DGD. It can be rotated or zoomed for viewing from different perspectives.
To rotate a 3D graph, drag it with the mouse. To zoom in or out, hover the mouse over it
and scroll up or down.
After the scan is finished, the data can be saved to a file by clicking “SAVE DATA”.
Data is saved as a text file with 3 columns: DGD, SOPMD, and DOP.
