Marker ->
Accesses the marker function menu keys that change value of center frequency or 
reference level to the current value of the selected marker.
Mkr -> CF
Sets the center frequency equal to the specified marker frequency, which moves the 
marker to the center of the screen. In delta marker mode, the center frequency is set to the 
marker delta value. This feature is not available in zero span.
Mkr -> RL
Sets the reference level to the amplitude of the specified marker. In delta marker mode, 
the reference level is set to the amplitude difference between the markers. (For example, if 
the difference is –15 dB, the reference level will bet set to –15 dBm.)
