c) In the "Center" field, enter
64
on the number pad on the front panel.
d) Press the "MHz" key next to the number pad.
2. Reduce the span to 20
MHz:
a) In the "Span" field of the "Frequency" dialog box, enter
20
MHz
.
b) Close the "Frequency" dialog box.
3. Set the reference level to -25
dBm:
a) In the configuration "Overview", tap the "Amplitude" button.
b) In the "Value" field of the "Amplitude" dialog box, enter
-25
dBm
.
The display of the calibration signal is now improved. The maximum at the center
frequency (=calibration frequency) of 64
MHz becomes visible.

Displaying a Spectrogram
In addition to the standard "level versus frequency" spectrum display, the R&S
FSV/A
also provides a spectrogram display of the measured data. A spectrogram shows how
the spectral density of a signal varies over time. The x-axis shows the frequency, the y-
axis shows the time. A third dimension, the power level, is indicated by different colors.
Thus you can see how the strength of the signal varies over time for different frequen-
cies.
1. Tap the "Overview" softkey to display the general configuration dialog box.
2. Tap the "Display Config" button.
The SmartGrid mode is activated, and the evaluation bar with the available evalua-
tion methods is displayed.
