Unlike time domain measurements, which use Oscilloscope, frequency domain measurements use Spectrum Analyzer. The article describes the characteristics and applications of Spectrum Analyzers, and the features that one may need to consider while buying a spectrum analyzer.

Spread Spectrum a kind of signal modulation, in which the signal frequency is spread over a very wide bandwidth. The band spread is achieved by chipping the signal with a code which is independent of signal. A code synchronized reception at the receiver is used for despreading and subsequent data recovery. Though started as a military application, it soon received applications in civilian communications.
