In the acquisition window, data is presented both in a graph and in a grid.
In the grid, the information is given for all the Out ports of the current
sequence. Depending on the type of the selected graph, certain items will
differ.
³
If the selected graph corresponds to an acquisition trace (IL trace, PDL
trace or ORL trace), the X axis will represent wavelength values and
the Y axis, dB values. The grid will show the greatest value among all
the values that have been measured for a particular test type.
³
If the selected graph corresponds to an analysis curve, the X axis will
present absolute time values and the Y axis, will present dB values,
except for a Central Wavelength curve for which the Y axis will present
values in nm.
The grid will show all the values that have been
measured for a particular test type, at a given time.
Note: A change in the graph type will be effective on the next acquisition only.
There are three buttons to control the execution of the test:
³
Start: Allows you to start the acquisition process. Once the test has
started, all the menus and buttons become disabled except for the
Pause and Stop buttons. At the end of the test, menus and buttons
become enabled.
³
Pause: Allows you to momentarily stop the test. When a test is paused,
it is possible to adjust graph settings and to export the results. Simply
click Resume to restart the test.
Pausing the test is only possible
between sequences.
³
Stop: Allows you to stop completely the test. Stopping the test is only
possible between sequences.
