Two Port Insertion Loss Measurement
Mode
Normal  Activates a single marker at the center of the display. 
Delta  Activates a pair of markers, one of which is fixed at the current marker location. The 
other marker can then be moved around on the trace. The marker readout shows the 
difference between the two markers.
NOTE Pressing Delta moves the reference marker to the active marker 
position, so you can make delta measurements from differing reference 
points without having to turn off the markers and begin again.
Off  Turns the selected marker off.
