  1. Advanced fpga technology is introduced to improve the integration of digital circuits, and all digital circuits in the original module are integrated in the fpga chips, which could not only reduce the cost, but also improve the reliability and measurement precision of the circuits. high speed digital signal processor ( dsp ) is selected as the coprocessor instead of scm ; it can receive all kinds of commands sent from vxi, analyze and execute the commands, harmonize each section of the module and process the data. higher - conversion - speed comparator chip is adopted to convert the input signals being measured into square waveform signals which could be identified by fpga chip ; it can expand the measurement range of frequency dramatically

    本文在原有vxi總線四通道計數器模塊的設計基礎上,通過對原模塊缺陷的分析,採用一些新的技術和新的電子器件來重新設計該計數器模塊:採用最新的fpga技術來提高數字電路的成度,將原模塊中的所有數字電路全部成在fpga晶元中,這樣不僅能節約成本,還能提高電路的可靠性和測量精度;採用高的數字信號處理器( dsp )取代原有的單片機作為協處理器,來接收vxi發來的各種命令,分析命令、執行命令、協調模塊各部分的工作以及對數據的處理;採用更高的較器晶元將輸入的被測信號換為fpga晶元能夠識別的方波信號,能極大提高測量頻的范圍;採用d / a換晶元和隔離算放大器得到隔離通道所需的較電平,該較電平值能夠根據實際需求進行設置,能增強模塊的使用靈活性。
