Second Harmonic Distortion Performance Test

At each test frequency, a signal is applied whose amplitude meets the requirement for the

power at the first mixer. One or more low pass filters are inserted between the source and

the PSA under test to prevent the second harmonic of the source from artificially raising

the second harmonic product as it is displayed on the PSA. The Marker Amplitude

function is used to measure the level of the distortion product and the theoretical Second

Harmonic Intercept point (SHI) is calculated.

To reduce amplitude uncertainty due to flatness, a power meter is used to characterize the

PSA at the fundamental and 2

harmonic frequencies.
