Uses Spincore Pulseblaster 24 Bit, Spectrum MI4021, one DAC20 and a synchronization board.
|
|
\li line 0 for gate
|
|
\li line 1 for pulse
|
|
\li line 22 for trigger
|
|
\li line 23 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
