Which device detects and analyzes RF spectrum?

Explanation:
Detecting and analyzing RF spectrum involves measuring how signal power is distributed across frequencies. A spectrum analyzer does this by sweeping a range of frequencies and plotting amplitude versus frequency, so you can see where signals sit, their bandwidth, and any spurious content. This makes it the essential tool for identifying occupied channels, assessing spectral purity, and spotting interference. The other instruments don’t perform this kind of full-spectrum view: a Bit Error Rate Test Set measures data integrity on a link, a multimeter checks basic electrical properties like voltage and resistance, and NEXRAD is a weather radar system.
