  • high-speed 4 - channel data acquisition system
  • all analog front-end parameters like amplification, offset and anti alias filter frequency are software programmable and on-board storable
  • no potentiometers or switches used
  • various phase optimized sampling modes possible
  • extension from 8, 12, 16... to 28 channel synchronous sampling possible when using several AD4-612 boards
  • external hardware triggering possible
