Delta Marker On/Off
This toggle function fixes the position of the reference marker and activates
the delta marker. This measures the difference between the active (reference)
marker and the delta marker. The front knob, step keys, or keypad can be
used to move the delta marker to the desired location.

If the delta function is turned on and no marker is active, Marker #1 will be
turned on and placed at the center wavelength as a reference for the delta
marker.
For Agilent 86144B/86146B only, if filter mode is enabled, the noise marker,
delta marker, and OSNR marker are disabled.
