Abstract
A method for measuring the phase jitter and phase noise of a signal-under-test (SUT) includes providing first and second oscilloscopes each having a timebase reference oscillator, the timebase reference oscillator of each of the first and second oscilloscopes configured to generate a timebase reference signal of a given output frequency. The method further comprises phase-locking the timebase reference oscillators of the first and second oscilloscopes together, applying the SUT to an input channel of the first oscilloscope and to an input channel of the second oscilloscope, and generating a first phase jitter measurement of the SUT using the first oscilloscope and generating a second phase jitter measurement of the SUT using the second oscilloscope. The method still further includes obtaining the phase noise of the SUT from the first and second phase jitter measurements to obtain the phase noise of the SUT.
