M2i - new generation of PC instruments


The new M2i card series generation is the successor of the former MI series. The M2i series offers some outstanding features:

Completely new developed base card
4 GByte memory with one slot width
Optimized low jitter clock section
Multi, Gate, ABA with programmable pre, posttrigger and timestamp
Zero phase delay synchronization
AND/OR conjunction of trigger/gate

Please click on one of the following links to get detailed information on the sucessor cards of the M2i series M2i.7005, M2i.7010, M2i.7011, M2i.7020, M2i.7021


MI.70xx Family

The MI.70xx series of fast digital I/O boards offer a resolution between 16 bit and 64 bit with a maximum sampling rate of 125 MS/s (60 MS/s). Every 16 bit / 32 bit of the board could be separately programmed for input or output. The on-board memory of up to 512 MByte could be used completely for recording or replaying digital data. Alternatively the MI.70xx could be used in FIFO mode. Then data is transferred on-line to PC memory or hard disk. The internal standard synchronisation bus allows synchronisation of several MI.xxxx boards. Therefore the MI.70xx board could be used as an enlargement to analogue boards.
