對 NI-HSDIO 裝置設定每個 Cycle 的三態〈Tristate〉 我如何對我的 NI-HSDIO 裝置的每一個 channel ，每一個 cycle 設定 tristate？ 當我試著在 LabVIEW 中設定此動作，結果在 niHSDIO Write Named Waveform (WDT).vi 中發生了 1074118585 的錯誤。 URL: http://digital.ni.com/public.nsf/allkb/87A0189AC1DFBC1B862572A6004DD4C2

External Clocking for HSDIO Devices I would like to use an external clock to acquire and generate data on my HSDIO devices, at frequencies that may not be integer divisors of the onboard clock. What options do I have? URL: http://digital.ni.com/public.nsf/allkb/B36B9D1B2FC55CBF862571F9000072BA

給 HSDIO 裝置的外接時脈〈External Clocking〉 我想要讓我的 HSDIO 裝置使用外接的時脈來擷取與產生信號，但是這個外接時脈的頻率卻不能被 HSDIO 裝置上內建時脈頻率整除，那麼我該如何做到這點？ URL: http://digital.ni.com/public.nsf/allkb/61A67FFE3255E1158625732B000645E4

What is the HWS File Format? Problem: What is the HWS file format? Solution: Hierarchical Waveform Storage data files are proprietary file types for National Instruments. They are written as binary files, and are used for storing digital waveforms. For more information, refer to the related links.

使用HSDIO来设定多个Script Trigger。 我想在HSDIO中使用script和software trigger来发送多个波形。然而，我只有4个trigger可以使用，现在我想产生超过4段以上的波形，怎么办？ URL: http://digital.ni.com/public.nsf/allkb/76C7524542667EED482571DB003785C1

Missing the First Sample with NI-HSDIO Devices I am generating a signal, exporting the clock and reading the signal back. I am triggering the acquisition off the data active event, and if I select to acquire my data on the same edge that it is generated, everything works as expected. However, if I generate the signal on the rising edge and URL: http://digital.ni.com/public.nsf/allkb/A70921E707DF94C0862571D800097A7C

HSDIO在使用外时钟时，动态发生产生错误的输出。 为什么当HSDIO使用外部时钟时，动态输出的信号是错误的？我把一个超过50MHz的信号接给了CLK IN，但是数字输出为60mV或是没有输出。 URL: http://digital.ni.com/public.nsf/allkb/83275E0EF860EBE2482571C000159C54

Multiple Script Triggers with HSDIO I am trying to generate multiple waveforms on my HSDIO device with the use of scripting and software triggers. However, I am limited to 4 triggers, and I need to generate more than 4 waveforms. What can I do? URL: http://digital.ni.com/public.nsf/allkb/419ACA21E67D65D2862571BC00613EFE

使用NI的数字波形发生/分析仪能够改变分配给通道的内存大小么？ 我没有全部用到数字波形发生/分析仪(NI 654x,655x,656x)的数字通道。能否进行板上内存优化，使得使用的通道得到更多的内存？ URL: http://digital.ni.com/public.nsf/allkb/5F16C11DD59A7777482571AA00444383

HSDIO Dynamic Generation with External Clock Gives Incorrect Output Why am I seeing an incorrect output when I dynamically generate a signal with an external clock on my HSDIO device? I am sending a reference clock above 50 MHz to CLK IN, but the digital output is only 60mV or nothing at all. URL: http://digital.ni.com/public.nsf/allkb/884C5A76BA1A474E8625717A0068AA09
