This facility is entered by pressing the Study button in the demodulator panel.
For each demodulation mode, its internal demodulator structure is revealed, accompanied by a set of observation and measurement tools.
The G315 demodulator relies on a quadrature (I & Q) representation of the incoming modulated signals.
The displayed interactive demodulator structure includes two real-time spectrum analyzers.
Each analyzer can be associated with any of the test points shown as colored dots in the diagram.
To connect the left spectrum analyzer to a particular test point, left-click on the green test point.
Within the displayed spectra, a cursor can be manually dragged over a particular spectral component, displaying its associated frequency and level.
A vector voltmeter also indicates the relative amplitude and phase difference between the two spectra at the cursor frequency.
