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

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

NI Data Acquisition Support for Intel-based (x86) Macintosh What National Instruments software, drivers, and data acquisition products are supported on Intel-based (x86) Macintosh machines? URL: http://digital.ni.com/public.nsf/allkb/3293B3137EA0C40A862571D8005AB68F

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

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

외부클럭을 이용한 HSDIO 다이나믹 생성을 하면 잘못된 출력이 나옴. 왜 외부클럭을 이용한 HSDIO 다이나믹 생성을 하면 잘못된 출력이 나옵니까? CLK IN에 50MHz 이상의 참조클럭 보내고 있으나, 디지털 출력은 60mV만 나오거나 혹은 전혀 나오지 않습니다. URL: http://digital.ni.com/public.nsf/allkb/EFFA706F2C658D8F8625719A0001DFC2

Firmware en la USB-6008/6009/6501 ¿Cómo se qué versión de firmware está instalado en mi USB-6008, USB-6009 ó USB-6501? Para poder usar NI-DAQmx Base necesito una versión y para usar NI-DAQmx 7.5 o superior necesito otra. ¿Cómo puedo usar ambos firmware en mi dispositivo?

Change Detection Considerations When Using DMA I am running the NI-DAQmx example for change detection on a device with a digital port of 8 bits. In some cases I only get an update after my generating device's digital lines have changed state 4 times, and in other cases I receive the NI-DAQmx error -200284. The lines to be detected are URL: http://digital.ni.com/public.nsf/allkb/53A4386656BBDC34862570DE005FDF77
