Signal Analyzers

Engineers use signal analyzers to combine the capabilities of spectrum and vector signal analyzers. A signal analyzer is a piece of electronic test equipment that takes measurements of power, magnitude, distortion, phase noise, modulation, and demodulation quality of input signals. Modern signal analyzers use digital techniques to monitor and extract useful information that the electrical signal carries. With the right software, a used or refurbished signal analyzer can measure virtually any aspect of an electrical signal.
