(2-1) 0.206 nm, -0.002 dB.
The color of the annotation denotes different characteristics of the markers:
•White annotation denotes the status of the currently active marker.
•Green annotation denotes the status of all currently used markers.
•Red annotation denotes that some type of an error occurred with the marker
measurement.
Moving the Active Marker from One Trace to Another
The following procedure shows you how to move the active marker (marker 1)
from Tr a ce A to Trace B.
1From the front panel, press Markers > Active Trace > TrB to make Trace B
the active trace.
2Press Active Marker > Mkr 1.
Measuring the Difference between Traces
The following procedure shows you how to find the amplitude and wavelength
difference between the maximum peaks of two different traces. Refer to “Nor-
mal/Delta Marker Interpolation (Marker Setup Panel)” on page 3-50.
1From the front panel, press Markers > Active Trace and select the first trace
to place a marker.
2Press Active Marker > Mkr 1 > Peak Search to place the marker on the
highest peak of the active trace.
3Press Active Trace and select the second trace to place a marker.
4Press Active Marker > Mkr 2 > Peak Search to place the marker on the
highest peak of the second trace.
5View the results of the measurement from the marker annota tio n a t th e top of
the display.
The wavelength and amplitude of each trace marker is shown, as well as the
amplitude and wavelength difference of the peaks of the two traces.
