A spectrum analyzer is a very important item of test and measurement equipment. It is used to measure the magnitude of a given input signal versus the full frequency range of the instrument. The spectrum displays data in a graph, which the frequency appears on the horizontal axis, and the amplitude is displayed on the vertical axis.

For measuring signals, speed is one of the most important specification that should be considered. GW INSTEK provides the fastest speed that users can easily handle and analyze modulation signals.

A spectrum analyzer looks very much like an oscilloscope. The difference between an oscilloscope and a spectrum analyzer is that oscilloscope allows you to view the signal in the time domain, meaning how the signal changes in response to time, but this equipment allows you to view the signal in the frequency domain, meaning how the signal changes in response to different frequencies.
