  • Patent number: 9835677
    Abstract: A system and method for determining the linearity of a device-under-test combine a first periodic signal and a second periodic signal to produce a combined signal, wherein the second periodic signal has at least one of a phase difference and a frequency difference with respect to the first periodic signal, and applying the combined signal to an input of the device-under-test. The linearity of the device-under-test is determined from an output signal of the device-under-test based on the at least one of the phase difference and frequency difference between the first periodic signal and the second periodic signal.

  • Patent number: 9632122
    Abstract: A method determines operating characteristics of a signal generator. The method includes performing a first set of measurements of an output signal generated by the signal generator and corresponding reflected signal, where the first set of measurements is performed over multiple frequencies and amplitudes of the output signal; applying an external signal to the output port of the signal generator; performing a second set of measurements of the output signal and corresponding reflected signal while the external signal is being applied to the output port, where the second set of measurements is performed over frequencies and amplitudes of the output signal, the external signal having the same frequency as the output signal for each measurement of the second set of measurements. A set of coefficients describing the operating characteristics of the signal generator is determined by processing results of the first and second sets of measurements through a non-linear model.
