Second Harmonic Distortion (SHD)

Test Limits
This test checks the second harmonic distortion of the signal analyzer by
tuning to twice the input frequency and examining the level of the distortion
product. A low pass filter is inserted between the source and the signal
analyzer to prevent the source second harmonic from artificially raising the
second harmonic product displayed on the analyzer.
