The implementation of a software based modal test system which incorporates both sine dwell and parameter estimation techniques is descri bed, The system utilises software to carry out some functions previously performed with hardware in order to decrease the hardware costs of the system as well as to increase flexibility. The sine dwell test technique has been streamlined by presenting the operator with a complete depiction in near real time of the behaviour of the structure. This as well as simple and convenient control of the excitation system has lead to a decrease in the time necessary to isolate modes and extract modal parameters.
