8.2 Measurement Functions

8.2.1 Marker

There are two operation modes of Markers due to Marker Number in operation. In single
Marker mode, Marker is used to read the frequency and level readings of signal on the
display.

This unit offers two modes of marker operation, single marker and multi-marker modes. In
single marker mode, the To Peak function will let the marker find and stand on the peak
signal. Marker to Center function will change the Center frequency to the marked
frequency by marker. Delta (

) mode will activate the delta marker, which will present both

the frequency and level differences with the reference marker.

The Multi-Marker mode can activate more markers up to ten. Under multi-marker mode,
the measurement readings are displayed on the marker table. Every marker can be specified
to be

∆Marker, and specify any other marker as its reference marker. Markers to Peaks

function allows the markers to find the peak signals automatically. It is very useful to pick
the EMI signals.
