Abstract
An arrangement is for measuring characteristic parameters of intermodulation distortion of a device under test. The arrangement may include a generator of at least two tones at different test frequencies, and an attenuation path feeding the device with a replica of the two tones attenuated of a factor equal to the gain of the device. The arrangement may also include a circuit for generating a difference signal between the signal output by the device and the two tones, and a circuit input with the difference signal and measuring the characteristic parameters as a function thereof.
