/**
\defgroup mobilemachine Mobile NMR Spectrometer
\ingroup machines
Uses Spincore Pulseblaster 24 Bit and Spectrum MI4021, but there is no cable driver with phase control
\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
