A spectrum analyser is an instrument that produces a graphical representation of signal amplitude as a function of frequency, within the frequency domain. It shows which frequency components are present in a signal and how strong they are.
Not all electrical systems can be described well in the time domain. For circuits such as filters, amplifiers, oscillators, mixers, modulators and detectors, analysing their frequency behaviour is often more effective. This behaviour is easiest shown by examining electrical signals in the frequency domain. This requires an instrument that can distinguish between different frequencies and measure their amplitudes. A spectrum analyser is the instrument used for this.
Good Will Instruments Co.LTD, founded in 1975, was Taiwan's first specialist manufacturer of electrical test and measurement equipment.

Benefits of spectrum analysers for deeper signal analysis
The frequency domain provides information not available in the time domain, giving a spectrum analyser advantages over an oscilloscope in some situations:
- Clearly displaying small harmonic distortion on a signal.
- Analysing noise signals.
- Determining carrier frequency, modulation frequency, modulation depth and modulation distortion of a modulated signal (AM and FM).
