Analog demodulation with a signal analyzer is used to extract and analyze the original information (audio, video, or data) from a modulated analog signal, such as AM (Amplitude Modulation), FM (Frequency Modulation), or PM (Phase Modulation). This process helps engineers evaluate the quality and integrity of the analog signal by examining key parameters like modulation depth (AM), frequency deviation (FM), or phase deviation (PM).

Using analog demodulation, engineers can assess signal distortion, noise, and interference, ensuring proper modulation performance and compliance with broadcast or communication standards. It is commonly used in applications like radio and television broadcasting, RF communication, and testing of analog signal transmission systems to diagnose problems and optimize signal clarity.

With the UNI-T UTS3000A Signal Analyzer UTS3000A-AMA option enabled, you can perform simple and complex analysis of analog modulated signals.
