Connections to External Systems

The WBA system is equipped with analog output for connection to data recording and analysis equipment.

Connections to motion analysis systems such as Vicon, MAC, Qualisys, Simi, CodaMotion, NDI, etc., can be easily made.


Use for MANY applications

One System, Many Applications

This full-featured, research-grade system is ideal for many different applications. Small and lightweight biosignal sensors are easy to place.  Your patient or test subject can move about freely and easily.  Measurement preparations are fast.

The batteries in all sensors are charged together in the supplied fast-charge recharger dock.

By turning on the sensors while still in the recharger dock, the sensor timing of all channels is synchronized.
