Phase Noise measurement / Audio Analysis /—Analog Demodulation Analysis function

The Phase Noise measurement relies on the excellent phase noise of the signal analyser and provides one-button automatic measurement to meet the daily signal source phase noise measurement applications. Independently optimised audio measurement channel for low frequency signal parameter measurement and analysis. Analog Demodulation Analyser is used to simulate terminal, radio, and general analog modulation source measurement. Demodulate the AM/FM/ΦM signal and measure parameters such as modulation index, modulation distortion, residual FM, and FM linearity and so on.
