Controllable high-speed multi-channel signal acquisition control circuit system and control method thereof

The invention provides a controllable high-speed multi-channel signal acquisition control circuit system. The system comprises an FPGA (field programmable gate array), wherein the FPGA is connected with an FOT (fiber optical transceiver) to realize communication with a host computer; the FPGA is connected with a DAC (digital-analog converter) chip to output analog signals for control or driving; the FPGA is connected with a plurality of AD (analog-digital) conversion chips to realize analog data conversion of multiple channels; the FPGA is connected with a reserved control port for an extending function. The controllable high-speed multi-channel signal acquisition control circuit system meets the work requirement for synchronous continuous sampling of a large quantity of analog signal channels, solves the problem of resource waste caused by repetitive design of a common high-speed multi-channel signal acquisition control circuit system, shortens the design time for a multi-channel signal acquisition circuit and is applicable to signal acquisition work on various occasions.
