Mar. 09, 2017

The function of the real time spectrum analyzer is to display the signal amplitude of the frequency domain in the same moment. Its working principle is there are correspondent filter and detector for different signal frequency, then transfer the signal to the CRT screen. The advantage of the real-time spectrum analyzer is the immediate reaction of the periodic random waves, and the disadvantages of it are the high price cost and the limited range of the frequency width.
