Log check box. The results of the analysis are logged to the file Analysis.txt in the Analysis
subdirectory.

Markers Tab Page

Two markers can be placed on any trace and moved around to obtain the wavelength or
frequency difference and the power difference, between any two points, on one or two traces.
The markers can be set in absolute wavelength or relative to a reference marker. To select the
reference marker, check the Reference Marker check box on the Markers tab page (Figure 74).
To place the first marker:
1. Select the channel.
2. Select the value for the y-axis, that is, whether the left-hand or right-hand y-axis values are to
be used.
3. Select the step size in points or pm for Marker 1.
4. Select the step size in points or pm for Marker 2.
5. Check the box labeled Show Markers.
After the first marker is placed, there are different ways to place other markers.
•
Place the marker by clicking at the selected spot. The marker is drawn on the plot and its
coordinates in wavelength or frequency and power are displayed in the appropriate boxes.
•
Enter the wavelength of the marker position and click the Find Y-Value button; the position of
the marker is then computed. The marker is drawn in place and the y-value is entered in its
edit field. When both markers have been drawn, the wavelength or frequency difference is
computed and displayed in the box labeled Delta. The difference in power is displayed in the
box beside it.
