HSDIO 的資料寬度〈Data Width〉與記憶體配置 什麼是 HSDIO 裝置的資料寬度；而這點會對每個通道記憶體配置有何影響？ URL: http://digital.ni.com/public.nsf/allkb/E2DB919A2E56FCA8862572AC0013FF98

当输入给 VCC 的电压小于 10VDC 时，PCI-6515 的 +5V I/O 连接管脚的电压是多少？ 在 PCI-6515 的规范中指出，如果 VCC 的电压高于 10VDC，那么 +5V I/O 连接管脚的输出为 5V，但是如果 VCC 的输入在 5V 与 10V 之间的话会是什么情况？ URL: http://digital.ni.com/public.nsf/allkb/D186AA3779A6A80E4825725800133CD6

Pattern Regeneration with PCI-6534 vs. PCIe-6536/37 I have an application developed for the PCI-6534 that performs pattern regeneration by storing a digital pattern in the onboard memory. I am interested in upgrading to the PCIe-6536 or PCIe-6537, but these cards do not have much onboard memory available for pattern storage.

利用 PCI-6534 與 PCIe-6536/37 作數碼重覆產生(Pattern Regeneration)的比較。 我有一個數碼重覆產生 (Pattern Regeneration)的程式，是利用 PCI-6534 卡上的記憶體來儲存數碼。現在我想要升級成 PCI-e6536 或 PCIe-6537，但是這些卡片並沒有多少卡上內建記憶體來儲存數碼。當利用 PCIe-6536/37 來做數碼重覆產生時，這些數碼要存在哪裡？這會影響效能嗎■> URL: http://digital.ni.com/public.nsf/allkb/4DEDF0BEBA1AFC0C86257275003382D9

What is the Value of +5V I/O Connector Pin on PCI-6515 when Input to VCC is Less Than 10VDC? In the specifications for the PCI-6515 it is mentioned that the +5V I/O connector pin will output 5V if VCC is greater than 10VDC, but what happens when the input to VCC is between 5V and 10V?

Toggling Rates for Digital Devices The specifications for my digital device state that the maximum clock rate of my device is 50 MHz. However, when I output a toggled signal (0, 1, 0, 1, …), the frequency that I’m seeing on my oscilloscope is only half of that maximum clock rate. Why is this so?

Input Capacitance for NI 654x High Speed Digitial I/O Devices For the NI 654x devices that use the 1 m SHC68-C68-D2 cable, the cable is rated for a typical 28 pF / ft, resulting in a capacitance of roughly 92 pF. Combined with the capacitance of the connector leads, the total capacitance of the cable can be estimated at 100pF. URL: http://digital.ni.com/public.nsf/allkb/EAA7AD955745C0678625720D0050BE03
