132Measuring Digital Communications SignalsSpurious Emissions MeasurementsSpurious Emissions MeasurementsThe following example demonstrates how to make a spurious emissionsmeasurement on a multitone signal used to simulate a spurious emission in ameasured spectrum.Step Action Notes1 Setup the signal source. a. Setup a multitone signal with8 tones with a 2.0 MHzfrequency spacing.b. Set the source frequency to1.950 GHz.c. Set the source amplitudes to−50 dBm.2 Connect the source RFOUTPUT to the analyzerRF INPUT as shown.3 Set the analyzer to theSpectrum Analyzer mode.• Press Mode, SpectrumAnalyzer.4 Preset the analyzer. • Press Mode Preset.5 Set the analyzer centerfrequency.• Press FREQ Channel,Center Freq, 1.950, GHz.6 Select the spuriousemissions measurement.• Press Meas, More, SpuriousEmissions.
