Abstract :
The use of a new signal, a multi-frequency coherent signal is presented for measurement of inter-modulation components caused by nonlinearity of transmission channel. This signal allows the use of digital coherent demodulation for measurement of inter-modulation components. It makes possible measurement of very weak signals, undetectable by non-coherent measurement.
