Synchronizing markers in Analog Demodulation windows
Now you have two Analog Demodulation channels. AnaDemod1 has an FM Spectrum
and an FM Time Domain window. AnaDemod2 has an RF Spectrum and an RF Time
Domain window. Only when the frequency marker in the FM Spectrum window is
moved, the marker in the RF Spectrum window is to move to the same position.
1. Select "Add New User Coupling".
2. From the "Channel 1" list, select "AnaDemod 1".
3. From the "Coupling Element 1" list, select "Frequency Marker 1".
4. From the "Specifics for Window" list, select window "1" (which is the FM Spectrum
window).

6. From the "Coupling Element 2" list, select "Frequency Marker 1".
7. From the "Specifics for Window" list, select window "1" (which is the RF Spectrum
window).
8. Select "Couple Selected Parameters".
9. In the "Parameter Coupling" dialog box, for the coupling definition for the frequency
markers in the Analog Demodulation channels, select the "Direction": "->"
10. Close the "Parameter Coupling" dialog box.
11. In the first AnaDemod channel, set the frequency marker in the FM Spectrum to
900 MHz.
