R3132 Series Spectrum Analyzer Operation Manual
5.2.15 Second Harmonic Distortion
5-55
5.2.15 Second Harmonic Distortion
A synthesized signal generator and low pass filter provide the signal for measuring second harmonic dis-
tortion. The low pass filter eliminates any harmonic distortion originating at the signal source.
The R3132 series frequency response is calibrated.
The signal generator is phase-locked to the spectrum analyzer’s 10 MHz reference.
Test will be done the points of 1.5 GHz and 1.9 GHz as fundamental signal.
To measure second harmonic distortion, use Fixed Marker in Delta Marker function.
