\defgroup bertamachine Berta NMR Spectrometer
|
|
\ingroup machines
|
|
Uses:
|
|
\li Spincore Pulseblaster 24 Bit (SP 17) which has a reference clock with 50 MHz
|
|
\li Spectrum MI4021 with gated sampling option (PB ref. clock is fed to Ext.Clock, impedance set to 1 MOhm)
|
|
\li Programmed Test Sources PTS 310 frequency synthesizer with phase control (0.225 degrees step size)
|
|
|
|
|
|
\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
