Spurious Emissions Measurements
The following example demonstrates how to make a spurious emissions
measurement on a multitone signal used to simulate a spurious emission in a
measured spectrum.
Step
1 Setup the signal source.
2 Connect the source RF
OUTPUT to the analyzer
RF INPUT as shown.
3 Set the analyzer to the
Spectrum Analyzer mode.
4 Preset the analyzer.
5 Set the analyzer center
frequency.
6 Select the spurious
emissions measurement.
Action
a. Setup a multitone signal with
8 tones with a 2.0 MHz
frequency spacing.
b. Set the source frequency to
1.950 GHz.
c. Set the source amplitudes to
−50 dBm.
• Press Mode, Spectrum
Analyzer.
• Press Mode Preset.
• Press FREQ Channel,
Center Freq, 1.950, GHz.
• Press Meas, More, Spurious
