Performance Tests

Harmonic, Subharmonic, and Nonharmonic Spurious Signals

3-20

Harmonic, Subharmonic, and Nonharmonic Spurious Signals

These automated tests verify that the harmonic, sub-harmonic, and non-harmonic spurious signals are within

specifications. The signal generator’s output signal is set to values where harmonic and spurious signal

performance problems are most likely to occur. Then the spectrum analyzer checks the level of the various

harmonic and spurious signals and compares each measurement to a signal of known frequency and

amplitude.

Recommended Equipment

• Agilent 8563EC Option 001 spectrum analyzer

• Agilent 8491A/B Option 010 fixed attenuator (10 dB)
