reference marker.  
The default readout mode in Zero span mode is ΔTime. 
 
  1/ΔTime  
In this type, the reciprocal of sweep time difference between the delta marker 
and reference marker will be shown. When the time difference is zero, the 
reciprocal is infinite and 100 THz is displayed.

marker is selected and is suitable for the frequency measurement of a video 
signal.
