/**
 \defgroup fc1neu_machine FC1neu NMR Spectrometer
 \ingroup machines
 Uses Spincore Pulseblaster 24 Bit and Spectrum M2i4021, and some DACs

 \par Starting the hardware
 This procedure should assure the correct initialisation of the hardware:
 \li Switch off main switches of SpinCore Pulseblaster and Computer (the main switch of the computer is at the rear)
 \li Switch on Computer and start Windows or linux
