2.9 Marker (Complementary Cumulative Distribution Function—CCDF)

Displays the Marker control menu for the CCDF measurement. All markers are off until

either Normal or Delta is pressed. There are three control modes for the markers:

•Normal (POSition) - A single marker placed at the 0 dB point of the selected value of

Marker Trace that can be moved to any point on the trace.

•Delta (DELTa) - Places the selected marker and the next marker at the position of the

previous marker on the specified trace (selected by pressing Marker Trace). The next

marker is the reference marker (set to normal) and the selected marker is a moveable

marker (delta) that you can place at any point on the trace. The difference between the

selected marker and the reference marker is displayed.

•Off (Off) - Turns off the active marker.
