summary method of testing a frequency synthesizer over a predetermined frequency range using a delay unit in accordance with a delay spectral distribution model modeling the delay spectral distribution of the delay unit over the predetermined frequency range; system capable of providing preset frequency signals; communication system, an electronic warfare system or radar system; communication system, an electronic warfare system or an adapted radar system; and radar system, a communication system, or an electronic warfare system a method of testing a frequency synthesizer over the predetermined frequency range that uses a delay unit in accordance with the delay spectral distribution model by modeling a spectral distribution of delay unit delay over the predetermined frequency range. the method comprises generating at least one test signal with the frequency synthesizer according to at least one test command; passing at least one test signal through the delay unit to obtain at least one delayed test signal; measuring at least one change of a signal attribute between the delayed test signal and the test signal; estimate an accuracy of the frequency synthesizer by comparing at least one measured change with an expected change, the expected change being derived from the delay unit delay spectral distribution model and at least one test command. 1/1
