/**
\defgroup mobilemachine Mobile NMR Spectrometer
\ingroup machines
Uses Spincore Pulseblaster 24 Bit and Spectrum MI4021, PTS310 with cabledriver with phase control and a synchronization board
\li line 0 for gate
\li line 1 for pulse
\li line 17 for trigger
\li line 16 for synchronization
\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
