Setting a marker on a
frequency relative to
marker 1
1 Enable a delta marker as described in “Enabling a delta marker”.
For the selected delta marker, the input field shows the frequency
relative to marker 1.
2 Enter a (signed) frequency relative to the frequency at marker 1,
either using the numeric keys and the respective enter key, or
moving the cursor to that frequency with the help of the cursor
keys.
The marker field indicates the desired frequency offset for that
marker, along with the power level relative to the power at marker
1.
Changing the center
frequency with a marker
This function modifies the center frequency, adapting the frequency of
a selectable marker.
1 From the main menu, select
Marker, or push the MKR function key
in any menu.
The Marker menu and the input field for marker 1 appear.
2 If you want to use the frequency at a marker position other than
marker 1, push the appropriate softkey (
A2 through A6 or B2
through
