我要如何用NI-DAQmx來控制Frequency Out (FREQ_OUT)訊號?



硬體: Multifunction DAQ (MIO)>>M Series, Multifunction DAQ (MIO)>>E Series

問題: 什麼是Frequency Out signal及要如何用NI-DAQmx來寫程式?

解答: Frequency Out or FREQ_OUT signal可以用程式產生數位脈波訊號,且可以在不用到卡片上的counter,M系列及E系列皆可如此,且M系列可以在任何的PFI接腳輸出,此訊號用到10MHz或100kHz的timebase,可以被任何1-16的整數除頻,此可產生32種不同的數位脈波,範圍從6.25kHz到10MHz,你可以在M系列及E系列的使用手冊中找到,在M系列中Help >> Counters >> Counter Timing Signals >> Frequency Output Signal or E Series Help >> Counters >> Counter Timing Signals >> Frequency Output Signal.
