2.4 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 fre-
quency 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 tem-
poral characteristics of power and frequency. The output data of the demodulator are
the basis for calculation of all relevant measurement results like modulation character-
istics or output power. The demodulator reaches a maximum in accuracy and tempera-
