The Analog Demodulation Option for the Narda SignalShark adds real-time AM and FM demodulation capabilities, allowing users to listen to analog signals directly through the analyzer. This feature is essential for signal identification, verification, and audio-based interference assessment in the field or lab.
This option enables the SignalShark to decode standard amplitude modulation (AM) and frequency modulation (FM) broadcasts within its frequency range. It provides adjustable audio filtering, squelch control, and volume settings. The demodulated audio can be output through the headphone jack or USB-connected audio interface, making it convenient for on-the-go field analysis.
With this option, operators can efficiently determine the nature of detected signals—whether they are legitimate communications, spurious emissions, or unauthorized broadcasts—by listening to the content in real time.
Key Features:
Real-time AM and FM audio demodulation
Selectable audio output via headphone or USB interface
Audio squelch and volume control
