Advanced Markers
Moving Markers
Moving markers can be moved to an arbitrary wavelength using the rotary knob, arrow
keys, or numeric keypad.
You can also drag the markers with the mouse.
Moving markers move along the waveform and show marker values (wavelength and
level) in the data area.
If two markers are displayed, the wavelength difference and level difference between the
markers are displayed.
When marker 1 (M1) and marker 2 (M2) are displayed: marker 2 – marker 1 (M2–1)
When marker 3 (M3) and marker 4 (M4) are displayed: marker 4 – marker 3 (M4–3)
The fixed marker function is not available.

Moving markers
A number is displayed with the moving marker.
When active, the marker is solidly filled.
Power Density Markers
Power density markers show power values per normalization bandwidth by assuming the
marker position on the waveform to be the center. The power values are displayed in the
data area. They are used to determine converted power values per given bandwidth such
as when measuring the signal noise level.
The selectable normalization bandwidth range is 0.1 to 10.0 nm. If you press the
COARSE key, you can set the value in 1 nm steps using the rotary knob or arrow keys. If
you do not press the COARSE key, you can set the value in 0.1 nm steps.
The way to move the markers and the data display between markers are the same as
with the above-mentioned moving markers.
