Digilogic Systems' Frequency Response Analyzer (FRA) functions by applying a frequency-swept sine wave to the device or system under test. This swept sine wave covers a range of frequencies of interest. As the sine wave sweeps through these frequencies, the FRA measures the response of the system in terms of gain and phase.
The FRA records how the system's gain (amplitude) and phase shift change at each frequency point. This data is typically represented graphically as a frequency response plot, where the x-axis represents frequency and the y-axis represents gain (amplitude) and phase shift. These plots provide a comprehensive view of how the system behaves across different frequencies.
Digilogic Systems' FRA is designed with precision and accuracy to capture subtle changes in gain and phase response. It may include features like high-resolution frequency sweeps, customizable frequency ranges, and advanced signal processing algorithms to extract detailed information about the system's frequency response characteristics.
