16 Analog Demodulation
Available with the optional "AM, FM, ASK, FSK Demodulation" application.
The analog demodulation application demodulates amplitude modulated (AM) and fre-
quency modulated (FM) signals, and shows various aspects of the modulated and
demodulated signal. You can view the results as numerical values or as a line trace in
a diagram to get an idea about the modulation accuracy of the signal.
Selecting the analog demodulation measurement application
1. Press the "Mode" key to open the mode menu.
2. Select the "Analog Demod" menu item.

Chapter 19.14.1, "Measurements and Result Displays", on page 303
The analog demodulation measurement application provides several measurements
and numerical and graphical result displays. These result displays show various
aspects and characteristics of the demodulated signal.
Selecting the measurement
The measurement type selects the modulation domain. The modulation domain
defines the type of signal you want to demodulate (FM or AM signal). The signal pro-
cessing is different, depending on the selected domain.
1. Press the "Meas" key to open the measurement menu.
2. Select the domain of the signal you want to demodulate.
● "AM Domain": Demodulates amplitude modulated (AM) signals.
● "FM Domain": Demodulates frequency modulated (FM) signals.
Make sure to apply a signal with the correct modulation domain. If you apply a sig-
nal with a different modulation than the selected domain, the results are not valid.
