Demo

Frequency Response Analysis (FRA) provides useful insights into stability and performance characteristics of control systems. Using the single sine technique, the CAPture FRA solution provides precise measurements of gain and phase between any two points in a system. The product is available in both single-channel and multi-channel configurations. Easily configured and controlled through the Windows based software that is supplied with it, CAPture FRA allows the managing of multiple runs and complex experimental sequences.

CAPture FRA is one in a suite of CAPture products, from Captronic Systems; the products targeting automated test requirements and control and acquisition requirements, across a diversity of industries.

Application Areas

Automated test systems
Aircraft control actuators
Aerodynamic loading systems
Automobile powertrain and suspension sub-systems
Propulsion and guidance systems
Electronic components specification definition
Power supply design and qualification
Impedance measurement in Electo-chemical / Bio-analytical systems
