The most common way of observing signals is to display them on an oscilloscope with time as the

X-axis (i.e. amplitude of the signal versus time) which is the time domain. Spectrum analyzer is  useful to display signals in the frequency domain. The providing this frequency domain view is the spectrum analyzer.

A spectrum analyzer provides a calibrated graphical display on its CRT, with frequency on the Horizontal axis and amplitude (voltage) on the vertical axis.
