Spectrum analyzers assist you in analyzing the characteristics of the electrical signals transmitted by electronic devices.

A spectrum analyzer also assists you in designing, manufacturing and repairing your electrical system. The analyzer performs various tests such as modulation, distortion and noise tests in order to identify the problem with your system. The analyzer also provides key information about your system's voltage, power and frequency .

Some important parameters you must consider before purchasing a spectrum analyzer are:

1. Frequency range, accuracy and resolution of the spectrum analyzer
2. Type of the analyzer: PC based or instrument based
3. Requirement of display: Analog, digital or video
4. Connectivity and memory storage device for the spectrum analyzer
