Distortion Verification
This test checks the Harmonic Distortion at selected frequencies and
harmonics. This test requires the use of a spectrum analyzer with
dynamic range, frequency range, and resolution bandwidth adequate for
the measurement.
Select each function generator output in the table below. Use a spectrum
analyzer connected to the function generator output. Set the fundamental
frequency reference to 0 dB and measure the 2nd through 5th harmonic
frequencies relative to this reference. This test is a 50
W output
termination test.
