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.
