LISA is composed of several modules which allow great architecture flexibility. It is really easy to organize and configure a very efficient combination of modules for a given in-flight test system.Up to 8 acquisition modules (i.e a total of 132 channels) can be used in the same test installation. Data sampling is isosynchronous over all these modules.Each acquisition module is equipped with a local removable storage (SD card) and be used as an independent data logger.
