3. Hardware Description
3.1. Overview
The modular concept of the MPA-3 system is designed to enable easy accommodation to a huge
variety of experimental requirements.
It is step by step expandable by up to three Quad ADC Port modules
2
to a maximum of sixteen
ADC inputs. It also features a versatile user programmable 8 bit digital input and output port.
Furthermore a programmable analog output is provided that allows to e.g. remote control a high
voltage supply etc. Moreover, three BNC connectors at the BASE module provide additional
programmable I/O features.
And, last but not least, a system wide open drain 'GO' line enables any connected device to start
and stop all participating measurement equipment simultaneously. This allows for easy
synchronization of electronic devices previously often not possible.
