9.3.4.1 Precise Frequency (Signal Count) Marker
Access: "Overview" > "Analysis" > "Marker Functions" > "Select Marker Function" >
"Signal Count" > "Signal Count Config"
Or: [MKR FUNC] > "Select Marker Function" > "Signal Count" > "Signal Count Config"
A normal marker determines the position of the point on the trace and indicates the sig-
nal frequency at this position. The trace, however, contains only a limited number of
points. Depending on the selected span, each trace point can contain many measure-
ment values. Thus, the frequency resolution of each trace point is limited.
(See also Chapter 8.5.1.8, "How Much Data is Measured: Sweep Points and Sweep
Count", on page 381).
Frequency resolution is further restricted by the RBW and sweep time settings.
