Normal Marker Units (Marker Setup Panel)
Sets the marker X-axis readout for frequency or wavelength when the instrument is in a non-zero
span. The X-axis default units is nm (nanometers). This setting controls only the normal marker X-
axis readout and the delta reference readout. This setting controls all four normal markers. The
bandwidth and delta offset markers have their own setting.

OSNR Marker
Indicates the signal quality based on the signal strength and noise level. Turning on the OSNR
marker will display four markers: an active marker, a center marker, and two noise markers. To
adjust the active marker to the desired measurement location, use the step keys, knob, or key-
board. The center marker is positioned at the closest peak to the active marker. The location of
the noise markers is determined by the selection of the Noise Method and the center marker. The
noise measurement is referenced to 0.1 nm noise resolution bandwidth.
