Abstract
One or more systems, devices and/or methods of use provided herein relate to a device that can facilitate a process to measure a pair of spectral sidebands and suppress one of common mode phase or amplitude noise. A device can comprise an interferometer device that can detect an interference of two spectral sidebands. The interferometer device can comprise a signal circuit that can detect at least one of a phase or an amplitude of a signal resulting from the interference of the two spectral sidebands, an IQ modulator that can generate the two spectral sidebands using a portion of a local oscillator (LO) microwave signal and a pair of signals at a same intermediate frequency, and/or a mixer that can interfere the two spectral sidebands having been output or reflected from a device under test, including mixing the two spectral sidebands with another portion of the LO microwave signal.
