PCIE high-speed acquisition card is a high-speed weak signal data acquisition card.
The PCIE high-speed acquisition card has a 12bit high-speed A/D converter onboard. When using 1 analog channel, the maximum sampling rate is 200MS/s; when using 2 analog channels, the maximum sampling rate is 100MS/s.
PCIE high-speed acquisition card has carefully designed a unique parallel synchronization signal acquisition and accumulation technology, so that acquisition and accumulation can be completed synchronously. The internal FPGA can average the collected data curve for a specified number of times and output the result (average number 0-32768 can be set).
The PCIE high-speed capture card has two trigger modes: external trigger and A channel trigger. Customers can arbitrarily choose to trigger the acquisition card mode or the acquisition card trigger device mode. After careful signal integrity processing, the overshoot of the trigger pulse given by the device is within 1%, and the superior signal quality ensures that the device will not be triggered by mistake. Reserve FPGA debugging port and some resources, allowing users to write algorithms and debugging by themselves.
