Abstract
A method for determining a distance to a passive intermodulation source in a device under test, the method comprising transmitting at least two signals with respective different frequencies to the device under test, receiving a complex response signal from the device under test, the complex response signal comprising a passive intermodulation of the at least two signals, generating an autocorrelation matrix using the complex response signal, the autocorrelation matrix representing power information of the complex response signal, decomposing the complex response signal, using the autocorrelation matrix, into a signal component part and a noise component part and determining a distance to the passive intermodulation source in the device under test using the noise and/or signal component part.
