Selected Marker
RSA3000E provides 8 markers. By default, Marker1 is selected under "Selected
Marker". After you select a marker, you can set parameters such as the marker mode,
the marker trace, and marker readout. The currently enabled marker will be marked
on the trace selected under Marker Trace. The readout of the currently activated
marker at the marker point will be displayed in the measurement result bar at the
upper-left corner of the screen.
Marker Mode
Sets the type of the marker. The available marker modes include Position, Delta,
Fixed, and Off.
1. Position
It is used to measure the X (Frequency or Time) and Y (Amplitude) values of a
certain point on the trace. When "Position" is selected, a marker indicated by a
number ("1") appears on the trace.
Remarks:
 If no active marker exists currently, a marker will be enabled at the center
frequency of the current trace.
 The readout resolution of the X-axis (frequency or time) is related to the
span. To obtain a higher readout resolution, reduce the span.
2. Delta
It is used to measure the difference between "reference point" and "certain
point on the trace": X (frequency or time) and Y (amplitude) value. When
"Delta" is selected, a pair of markers appears on the trace: Reference Marker
(marked by "X") and the Delta Marker ( m a rk ed b y "△") .
Remarks:
 If an active marker exists currently, then activate a reference marker at the
current marker; otherwise activate both the reference marker and Delta
marker at the same time at the center frequency.
 When you change the position of the Delta marker, the position of the
reference marker remains unchanged, but the frequency (or time)
difference between the two markers will change along with it.
 The frequency (or time) difference between the two markers and the
amplitude difference between them are displayed in the measurement
result bar at the upper-left corner of the screen.
