9 Measurement Example: Demodulating an
FM Signal
A practical example for a basic Analog Demodulation measurement is provided here. It
demonstrates how operating and measurement errors can be avoided using correct
configuration settings.
The measurement is performed using the following devices:
●
An R&S
FSW with application firmware R&S
FSW-K7: Analog Demodulation
●
A vector signal generator, e.g. R&S SMW
Signal
Generator
R&S FSW
Figure 9-1: Test setup
Signal generator settings (e.g. R&S SMW):
Frequency:
500 MHz
Level:
-10 dBm
Modulation:
FM
Modulation frequency:
10 kHz
Frequency deviation:
50 kHz
Procedure:
1. Preset the R&S
FSW.
2. Set the center frequency to
500
MHz
.
3. Set the reference level to
0
dBm
.
4. Select the MODE key and then the "Analog Demod" button.
By default, the FM Time Domain result display and a Result Summary are shown.
