Frequency Response Analyzers

Since 1979, Venable Instruments has been focused on one goal: bringing the most versatile, full-featured frequency response analyzers to customers in industries where precise testing and measurement tools for power supply design is critical. Over 37 years of continual research and development has created the widest range of scalable frequency response analyzers to meet your company’s current requirements, while providing a cost-effective growth path for increased testing functionality. 

A Frequency Response Analyzer (FRA) is a precision instrument used to measure the gain and phase response of electronic components and circuits, both active and passive. Results are displayed as a Bode plot or Nyquist plot. FRAs are used to measure device and system impedances, as well as plant (modulator), compensation (feedback) transfer functions and closed loop (feedback loop or servo loop) gain and phase. FRAs are considered frequency domain instruments and often used for stability analysis.
