What is an FRA?

A Frequency Response Analyzer (FRA) is a high precision measurement instrument used to analyse dynamic behavior of circuits & components of control systems in the frequency domain. An FRA generates a sinusoidal signal and inserted it into a unit under test. This signal is measured at the point of insertion using one of the input channels on the FRA The inserted signal travels through the UUT and the same signal is measured simultaneously by the FRA at other input channel. The technique measures the magnitude and phase relationship between output and input waveform as a function of frequency.
