Spectrum Analyzers

GAOTek Spectrum Analyzers are electronic test equipment wildly used in the test, maintenance, troubleshoot, and installation of radio frequency circuits and equipment. The spectrum analyzers are able to reveal the elements of the signal and the performance of the circuit producing them, which otherwise would not be easy to analyze.

The spectrum analyzers can monitor the levels of spurious signals, such as intermodulation products, noise, harmonics and other signals, to see whether they meet the required levels by displaying the frequency of the signals on the horizontal scale and the amplitude of signals on the vertical scale.


The spectrum analyzers are designed to test and check the response of networks and filters. They are wildly used to measure the bandwidth of modulated signals and discover whether they fall within the required mask. These devices can monitor tracking generator to see the loss at any given frequency. In this way, the spectrum analyzers make a plot of the frequency response of the network. Spectrum analyzers are also widely used in many signaling processes, an example of this would be optical analyzers.


GAOTek Spectrum Analyzers have adjustable spectral density range, auto-fitting time, frequency and spectral density rulers, and can run on many operating systems, such as MAC OS, Linux, and Windows. The spectrum analyzers also have built-in cut filters, gas purging input and output ports, and speed mode options, which increase the sweep speed. The spectrum analyzers can also be used to determine the bandwidth of a signal, and demodulate AM/FM/SSB/CW audio in real-time. You can see digital signal processing on PC after connecting the spectrum analyzers. These compact, portable, light-weight, and easy set-up spectrum analyzers are suitable for indoor and outdoor use.

Applications and Industries

These spectrum analyzers can measure and receive radio waves within given parameters to transmit data to a radio set or TV, also used in many industries that require measurement of sound levels. One of the important applications of the spectrum analyzers is in tape recorders, hand phones and speakers. They can be set to measure the light beams that LED such as diodes or lasers emit. They are widely used in determining the cause of interference to wireless networking equipment, such as Wi-Fi and wireless routers. They are widely used in environmental monitoring and many industries, such as security, healthcare, telecommunications, chemical analysis, sensing, and microscopy.
