1300.2519.12 4.55 E-11
To define the basic marker settings
1. Press the MKR key to open the marker menu.
Marker 1 is activated and positioned on the maximum value of the trace as normal marker. If
several traces are being displayed, the marker is set to the maximum value (peak) of the trace
which has the lowest number (1 to 3) and is not frozen (View mode). In case a marker is already
l
ocated there, it will be set to the frequency of the next lowest level (next peak).
2. To change to another trace, press the Marker to Trace softkey and enter the number of the trace
on which the marker is to be placed.
The marker changes to selected trace, but remains on the previous frequency or time. If a trace is
turned off, the corresponding markers and marker functions are also deactivated.
3. To switch on a delta marker, press the Marker 2 softkey.
Marker 2 is switched on as a delta marker. The frequency and level of marker 2 are displayed in
relation to marker 1 in the marker field.
4. To change the marker type of marker 2, press the /Marker Norm/Delta softkey.
Marker 2 becomes a normal marker. The frequency and level of marker 2 are displayed as absolute
values in the marker field.
5. To switch off marker 2, press the Marker 2 softkey again.
Marker 2 is deactivated. Marker 1 becomes the active marker for entry. The frequency and level of
marker 1 are displayed in the marker field.
To set a fixed reference point (phase noise measurement)
1. Press the Phase Noise/Ref Fixed softkey.
The submenu with the Phase Noise On/Off softkey switched on is displayed. The level and
frequency or time values of marker 1 immediately become the reference point.
2. To set the maximum of the selected trace as reference point, press the Peak Search softkey.
3. To define the values for the reference point, proceed as follows:
– Press the Ref Point Level softkey and enter a reference level value.
– If span > 0, press the Ref Point Frequency softkey and enter a frequency reference value.
– If span = 0, press the Ref Point Time softkey and enter a reference time value.
To set the demodulation mode and duration
1. Press the Marker Demod softkey.
The submenu with the Mkr Demod On/Off softkey switched on is displayed.
2. To change the demodulation mode, press the AM or FM softkey.
For details see "AF demodulation" on page 4.56.
3. To modify the demodulation time for span > 0, press the Mkr Stop Time softkey.
4. To change to continuous demodulation for span > 0, press the Cont Demod softkey.
5. To tune the volume for acoustic monitoring, press the Volume softkey.
