Displaying a Marker Peak List
The marker peak list determines the frequencies and levels of peaks in the spectrum
automatically. We will display a marker peak list for the "Spectrum 2" measurement
channel.
1. Tap the "Spectrum 2" tab.
2. Press the [Run Single] key on the front panel to perform a single sweep for which
we will determine the peaks.
3. Tap the "SmartGrid" icon in the toolbar to activate SmartGrid mode.
4. Drag the "Marker Peak List" icon from the evaluation bar to the lower half of the
display to add a new window for the peak list.
5. Close the SmartGrid mode.
6. To obtain a more conclusive peak list that does not contain noise peaks, for exam-
ple, define a threshold that is higher than the noise floor:
a) Press the [Mkr] key on the front panel.
b) Tap the "Marker Config" softkey in the "Marker" menu.
c) Tap the "Search" tab in the "Marker" dialog box.
d) In the "Threshold" field, enter
-68
dBm
.
e) Tap the "State" box for "Threshold" to activate its use.
Only peaks that are larger than -90
dBm will be included in the peak list.
f) Close the "Marker" dialog box.
The marker peak list displays the determined peaks that are above the defined
threshold.
