Functional Description – Block Diagram
The Adjacent Channel Power and EDR In–band Spurious Emissions measurements are performed in
the Spectrum Analyzer mode. For this test case the complete frequency band is scanned using a
sequence of zero span measurements.
All other test cases are based on a digital I/Q demodulator which determines the temporal
characteristics of power and frequency. The output data of the demodulator are the basis for calculation
of all relevant measurement results like modulation characteristics or output power. The demodulator
reaches a maximum in accuracy and temperature stability by sampling the IF signal and converting it
digitally down into the base band (I/Q area).
