how to drive two shakers simultaneously?

[asadi]

Hi,

I wish to perform a MIMO modal analysis by using two shakers and two accelerometers and control and monitor them simultaneously.

Which hardwares do you suggest and is it possible by LabVIEW vibration toolkit?

You should investigate the 4461 to verify that it meets your performance requirements. The 4461 supports two high-quality analog inputs and two high-quality analog outputs. LabVIEW and the Sound and Vibration Toolkit can be used to configure and control the analog channels in order to perform MIMO testing. The following document on modal parameter extraction should also be helpful as you move forward: http://zone.ni.com/devzone/cda/epd/p/id/6121
