Product overview:
PCIE high-speed acquisition card is a high-speed weak signal data acquisition card.
The PCIE high-speed acquisition card carries a 12bit high-speed A/D converter. When one analog channel is used, the maximum sampling rate is 200MS/s; When two analog channels are used, the maximum sampling rate is 100MS/s.
PCIE high-speed acquisition card has carefully designed a unique parallel synchronous signal acquisition and accumulation technology, so that the acquisition and accumulation can be completed synchronously. The internal FPGA can average the collected data curves for a specified number of times and output the results (the average times 0-32768 can be set).
PCIE high-speed acquisition card has two trigger modes: external trigger and channel A trigger. The customer can choose the mode of triggering the acquisition card or the mode of triggering the device by the acquisition card at will. After careful signal integrity processing, the overshoot of the trigger pulse given by the equipment is within 1%, and the superior signal quality ensures that the equipment will not be triggered by mistake. FPGA debugging port and some resources are reserved, allowing users to write algorithms and debug by themselves.
