Types of Spectrum AnalyzersĪ spectrum analyzer is similar in concept and architecture to a basic radio receiver. This need extends from the concept phase for new communication devices to the field testing that guarantees QoE. The spectrum analyzer remains the best and only test solution for verifying and troubleshooting performance in this complex environment. Inevitable outputs of the wireless revolution have included high spectrum utilization and channel density, diverse interference sources, and a host of duplexing and multiplexing options to squeeze more bandwidth out of airwaves and fiber. Today’s spectrum analyzers are a source of detailed insight into signal frequency (in MHz or KHz), amplitude, phase, and modulation behavior. In their earliest incarnation, this functionality distinguished the spectrum analyzer from the oscilloscope by introducing a window into the frequency domain of the signal in addition to the time domain. Spectrum analyzers are used to measure the magnitude of signal input vs. As the airwaves become more crowded in response to rapidly evolving technology and demand, you simply cannot do your job without a spectrum analyzer.
