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. SOPMD 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”.
Data is saved as a text file with 3 columns: DGD, SOPMD, and DOP.
Scan DGD and SOPMD:
This function performs a scan of a 2-D grid in PMD space. The user defines the grid by
specifying the DGD and SOPMD limit points and step sizes.
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. As each point is
generated, the DGD, SOPMD, and output DOP are displayed above the graphs, and the
output DOP vs. DGD is plotted in the graph on the left.
The data is also plotted in a 3D graph on the right of the screen. The graph can be rotated
or zoomed to view the data from different perspectives.
