The settings correspond to the most common commands in the Trace – Trace Select, Trace – Trace
Funct, Trace – Meas, Trace – Format and Trace – Scale menus.
Markers
Markers are tools for selecting points on the trace and for numerical readout of measured data. The
analyzer provides three different basic marker types.
•
A (normal) marker (Mkr 1, Mkr 2, ...) determines the coordinates of a measurement point on the
trace. Up to 10 different normal markers can be assigned to a trace.
•
A reference marker (Ref) defines the reference value for all delta markers.
•
A delta marker (
∆
) indicates the coordinates relative to the reference marker.
•
The stimulus value of a discrete marker always coincides with a sweep point so that the marker
does not show interpolated measurement values.
The markers 1 to 4 are also used for bandfilter search mode. The examples below show a bandpass
search and a bandstop search, respectively.
