Using the Markers 
The R&S FSH has a marker and a delta marker to make it easier to read off trace values. The markers 
cannot leave the trace and indicate the frequency and level of the point they are positioned on. The 
frequency indicated by a marker is shown by a vertical line which extends from the top to the bottom of 
the measurement diagram. The numeric frequency and level readouts are displayed in the top left-hand 
corner of the screen. The unit is the same as the unit of the reference level. 
The position of the delta marker is indicated by a dashed line to distinguish it from the other marker. 
The delta marker level is always a level relative to the main marker level and so the delta marker level 
unit is always dB. The delta marker frequency is always relative to the main marker – in other words, 
the delta marker frequency is the frequency difference between the frequency at the point marked by 
the main marker and the frequency at the point marked by the delta marker.

Controlling the marker: 
 
 Press the MARKER key. 
The marker menu opens. If, as yet, no marker has 
been activated, the main marker (MARKER) is turned 
on automatically and placed on the maximum level in 
the spectrum. The frequency and level at the point 
indicated by the marker are displayed at the top of the 
screen in the selected unit (= reference level unit). The 
value entry box for the marker frequency opens. 
 
The following actions can now be performed: 
 Change the marker position using the rotary knob 
or the cursor keys. 
 Enter a marker position with the number keys and 
terminate the entry with one of the unit keys. 
 Confirm the marker position by pressing the 
ENTER key or the MARKER softkey.
