E-Mobility Basic Measurement SystemAs core of the measurement system, the Basic Measurement System contains the most important components for mastering most measurement tasks.
Vector Data Logger / InterfacesIf, in addition to analog measurement data, data from the vehicle buses or ECUs have to be synchronously acquired, components of this expansion stage are used. In addition, powerful loggers are located in this expansion stage.
CSM Data LoggersFor the recording of measurement data the data loggers UniCAN 3 can be used.
Data Analysis and Measurement Data ManagementIf more precise analyses or measurement data management in the cloud are required, the Vector software packages of this expansion stage are suitable.

The robust and compact design of all components makes the measurement system ideal for mobile use on test drives and also on test bench.
