Abstract
A method of measuring the AM/PM conversion of a device under test having a local oscillator is described. A device under test with an embedded local oscillator is provided. A signal source is connected to an input of the device under test. A receiver is connected to an output of the device under test. An input signal is provided by the signal source. The input signal has an initial power level. The input signal is input to the device under test. The power level of the input signal is changed. An output signal of the device under test is measured at different power levels of the input signal.
