Reading The Marker Position Time Or Relaxation Time; Analyzing The Equivalent Circuit And Simulate The Frequency Characteristics - Keysight E4990A Help Manual

Reading the marker position time or relaxation time

You can use the following procedure to select how the sweep parameter
value is displayed in the Marker Sweep Parameter Value field: time relative
to the sweep start or relaxation time. This function allows you to read the
sweep parameter value in a unit of time at each point on the trace in the
zero span sweep.

sweep parameter value (marker X-axis) only when the frequency is
selected as the sweep parameter. When you use the ∆ marker, the
relative value from the ∆ marker position is displayed in the Marker
Sweep Parameter Value area, regardless of the selection of the
marker sweep parameter value (marker X-axis) display.
