Description
Second harmonic distortion in the non-preselected and preselected
bands is checked with a signal source and low-pass filter. The
low-pass filter ensures that the harmonics measured are due to the
analyzer and not the source. Third-order intermodulation distortion
is measured in the non-preselected and preselected bands with two
signal sources. To prevent source interaction, the synthesizer outputs
are padded and combined in a reactive power divider.
