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 Trace A to
Trace B.
1 From the front panel, press Markers > Active Trace > TrB to make Trace B the active trace.
2 Press 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.
tion (Marker Setup Panel)" on page
1 From the front panel, press Markers > Active Trace and select the first trace to place a marker.
2 Press Active Marker > Mkr 1 > Peak Search to place the marker on the highest peak of the active
trace.
3 Press Active Trace and select the second trace to place a marker.
4 Press Active Marker > Mkr 2 > Peak Search to place the marker on the highest peak of the second
trace.
5 View the results of the measurement from the marker annotation at the 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.
