The resulting data is stored in a single HDF5 file per recording.</p> <p>Note: When interfacing with external hardware, signals can only be saved to a file for frame rate values larger than 17 frames per second.</p> <p>Additional I/O port functionality is not available on V1 hardware.</p> <p><em>*Note: The nVista HD V2 System is back-compatible with USB2 ports, but the ability to save imaging data in .HDF5 format is lost.
