PCI-6624 周期测量精度 利用 PCI-6624 执行一个周期测量时，精确度是 500 ns。时基是 20 MHz，为什么精确度不是 50 ns？ URL: http://digital.ni.com/public.nsf/allkb/8FA81810C8B94B7B4825718C00325504

当指定主时基（MasterTimebase）时，6602使用 80MHz 时钟 当您执行周期测量并指定主时基为 CI.CtrTimebaseSrc 并且 20MHz 做为 CI.CtrTimbebaseRate，板卡仍使用 80MHz 时钟。已经设置为使用主时基，但仍使用 80MHz 时钟。为什么会这样？ URL: http://digital.ni.com/public.nsf/allkb/61017AAFFE1C92014825718C000FE2B3

SCB-68是否支持NI 5411（或者5431）？ 我把SCB-68用在我的NI 5411（或者5431）上，可是我发现第6、7位信号线产生的数据并不总是正确的。 URL: http://digital.ni.com/public.nsf/allkb/562E7849530525B54825710F00056FA2

Triggered Buffered Counting on Multiple Cards Running Slower Than Expected I have multiple counter cards doing buffered event counting. When I use a start trigger for this acquisition it runs much slower than if I just let them start when the VIs are called. Why is this going slower than expected?

6602 Uses 80MHz Clock When MasterTimebase is Specified If you are doing a period meausurement and specify MasterTimebase as the CI.CtrTimebaseSrc and 20MHz as the CI.CtrTimbebaseRate the board still uses the 80MHz clock. It appears that setting it to use MasterTimebase, does nothing since it uses the 80 MHz clock anyway. What's going on? URL: http://digital.ni.com/public.nsf/allkb/8F4E079D09395709862570C90071330E

6602 보드에서 MasterTimebase 를 설정시 80MHz 클럭의 사용 MasterTimebase 로 CI.CtrTimebaseSrc 를 설정하고 CI.CtrTimbebaseRate 를 20MHz 로 설정한 후 주기측정을 하는데 보드는 여전히 80MHz를 사용합니다. 이것은 MasterTimebase 의 사용을 설정했는데 여전히 80MHz를 사용하는 것으로 보여집니다. 무슨 문제입니까? URL: http://digital.ni.com/public.nsf/allkb/77DF052C66476002862570CF000939AF

6602でタイムベースソース(TimebaseSrc)にマスタータイムベース(MasterTimebase)を設定した場合の実際のタイムベース カウンタの周期測定などで、CI.カウンタタイムベースソース(CI.CtrTimebaseSrc)をマスタータイムベース(MasterTimebase)に設定し、CI.カウンタタイムベースレート(CI.CtrTimebaseRate)を20MHzに設定しましたが、実際のタイムベースは80MHzになっているようです。どうなってい■> URL: http://digital.ni.com/public.nsf/allkb/CE1FC32890699FD88625716A00356745

Does the SCB-68 support the NI 5411 (or 5431)? I want to use my SCB-68 break out board with my NI 5411 (or 5431), but I am noticing that bits 6 and 7 are not always generated correctly. URL: http://digital.ni.com/public.nsf/allkb/FD0B2EA306BFF5FB862570C7007EECFC

SCB 68이 NI 5411(또는 5431)을 지원합니까? SCB 68 브레이크 아웃 보드를 NI 5411(또는 5431)과 함께 사용하려고 합니다. 그러나 비트 6과 7이 항상 정확하게 생성되지 않습니다. URL: http://digital.ni.com/public.nsf/allkb/EF6BCDF8EB0DAB09862570CF000696C0

請問SCB-68有支援NI 5411(或5431)? 我想使用SCB-68將我的NI 5411(或5431)的接點外接出來,但是我發現第6或7位元所產生的訊號有問題。 URL: http://digital.ni.com/public.nsf/allkb/9960FAAF2A014C9D862570CF003B0457
