All markers can be used either as markers or delta markers. The marker that can be moved by the user
is defined in the following as the active marker. Temporary markers are used in addition to the markers
and delta markers to evaluate the measurement results. They disappear when the associated function
is deactivated.
The measurement results of the active marker (also called marker values) are displayed in the marker
field. The marker field is located at the upper right corner of the display and shows the following:
• marker type (M1 in the example)
• trace in square brackets ([1] in the example)
• level (–33.09 dBm in the example)
• marker location (3 GHz in the example)

The MKR key is used to select and position the absolute and relative measurement markers (markers
and delta markers). In addition, the functions for frequency counter, fixed reference point for relative
measurement markers and enlargement of the measurement area are assigned to this key.
Also the following measurements can be carried out:
• Noise density (Noise Meas On/Off softkey; see also "Measurement of noise density" on page 4.56)
• Frequency measurement (Sig Count On/Off softkey; see also "Frequency measurement with the
frequency counter" on page 4.56)
• Filter or signal bandwidth (n dB down softkey)
• AF demodulation (Marker Demod softkey; see also "AF demodulation" on page 4.56)
For further information on markers see also "Changing Settings via Markers – MKR–> Key" on page
