Can I Use Different Sample Clocks for Correlated DI and DO? On M-Series and CompactDAQ multifunction data acquisition boards, both Digital Input (DI) and Digital Output (DO) tasks can be correlated to an external signal. Can I use a different external signal for the DI and DO tasks? URL: http://digital.ni.com/public.nsf/allkb/79608CDF0C0D28AA862573400042D4F8

我可以在 Correlated DI/DO 使用不同的 Sample Clock 嗎？ M 系列與 CompactDAQ 多功能資料擷取卡的數位輸入〈DI〉與數位輸出〈DO〉task 都可以將 sample clock 設定與外接 clock 信號相關聯〈correlated〉。我可以為 DI 與 DO 設定不同的外接 clock 信號嗎？ URL: http://digital.ni.com/public.nsf/allkb/4A749CBBF015DF3E8625734900388364

Decreased Counter Measurement Resolution With Digital Filtering Why does my counter resolution decrease when I use a digital filter on a counter input task with an NI M-Series or TIO device? URL: http://digital.ni.com/public.nsf/allkb/176C93DAEB2FD1798625733A004D295D

将数字滤波器设为有效的时候，计数器返回了不正确的测量值 当我在使用NI M系列板卡或者TIO板卡进行计数器输入任务的时候，使用了数字滤波器。为什么计数器的测量值不正确呢？ URL: http://digital.ni.com/public.nsf/allkb/378B112E4E57EC63862573C90049ED22

PFI lines of a PCI-6232 for quadrature encoder measurements How can I connect a quadrature encoder to a PCI-6232 with a CB-37-HVD connector block? URL: http://digital.ni.com/public.nsf/allkb/79C0136B7DAFE01E86257323005A58C5

Internally Routing Counter Signals in LabVIEW I want to route the output signal of one counter to the source/gate of another counter on the same card or to a specific PFI line. Can I do this without externally connecting the two pins? URL: http://digital.ni.com/public.nsf/allkb/8A85E97855EDADC98625730C00065F58

怎么才能够在LabVIEW下路由计数器的输出 我想要将一个计数器的输出路由至同一块板卡上的另一个计数器的source/gate端或者到一个特定的PFI引脚上。我能否不通过外部连接着两个引脚而实现这样的功能？ URL: http://digital.ni.com/public.nsf/allkb/C49A281133F4D39F862573C900442CDE

Why Do I Receive Drift Readings when Using Analog Input on My DAQ Device? When I feed a voltage source through an analog input channel on my DAQ device, I see the voltage drift. Why is this happening when I am feeding the device a constant signal? URL: http://digital.ni.com/public.nsf/allkb/08384B7B2ADD360D862572F1003DEC29

為什麼我在使用我的DAQ裝置做類比輸入時會讀到飄移的值? 當我輸入一個電壓訊號給DAQ裝置的類比輸入, 我看到電壓在漂移. 為什麼我給的是一個固定的電壓值卻會發生這樣? URL: http://digital.ni.com/public.nsf/allkb/51553B5F4FC87E248625741F0036F9CB

Error -200474 With Digital Frequency Example VIs Modified for Continuous Acquisition I modified the Meas Dig Frequency-Low Freq 1 Ctr example VI to acquire continuously, and unless there is a signal with a frequency greater than 100Hz, I get Error -200474. What is wrong and how can I fix it? URL: http://digital.ni.com/public.nsf/allkb/4E017925BDF2DC2D862572E6007C9594
