Spectrum analyzers are adopted to analyze signal frequency and amplitude in logarithmic scale when the electric signal pass through the system such as real-time spectrum analyzer. Spectrum analyzers are widely adopted for manufacturing, designing and engaging in the field services and repairs electrical devices and are also used to determine performance, error detection and troubleshooting errors.
Measurement of quality of modulation is carried out for smooth transmission of data and it is crucial in both transmission and receiver end. The important characteristics of spectrum analyzer are signal to noise ratio test and noise figure test which improves overall performance of the system. With a rising boom in telecommunication industry and increase in wave analysis, spectrum analyzer market has flourished with many new emerging players such as Keysights Technologies and LP Technologies.
