Analyzing Measurement Data
This section provides advice and information on the following analyzer functions that allow you to
analyze the measured amplitude wavelength data.

Tips for Using Traces and Markers
The analyzer provides the ability to display up to six traces with up to four markers. Knowing a
few tips makes trace and marker manipulation much easier.

• Markers are always placed on the currently selected active trace. Therefore, use the Active Trace
function to activate the desired trace, then select an active marker to be placed on that trace.
• When multiple markers are currently used on multiple traces, the Marker Status area (located at
the top of the display) makes it easy to identify the state of each marker.
Information provided for each marker includes:
• Wavelength
• Amplitude
• The trace associated with the marker.
For example, if marker 1 is on Trace A then the annotation will show
Mkr 1 (A).
In addition, if there are two markers on, then the delta of the wavelength and amplitude for
the two different markers is also displayed. For example, Mkr (2-1) 0.206 nm, -0.002 dB.
