How Can I Perform a Self-Test of My NI-DAQmx Device Programatically in LabVIEW? I want to programatically perform an NI-DAQmx Self-Test in LabVIEW, similar to that available in Measurement and Automation Explorer, but I can't find the corresponding VI. Where can I find this VI or how should I implement a self-test in my program? URL: http://digital.ni.com/public.nsf/allkb/4927D77E27D907CF8625741F006C987B

如何在LabVIEW裡用程式的方法對NI-DAQmx的裝置進行Self-Test? 我希望在在LabVIEW裡用程式的方法對NI-DAQmx的裝置進行Self-Test, 就像我們在Measurement and Automation底下做的一樣。但是我找不到對應的VI。請問我要在哪裡才可以找到這個VI?或是我應該怎樣在我的程式裡執行self-test? URL: http://digital.ni.com/public.nsf/allkb/0D7A321CAC2E4B658625742500231A4D

Can I Use a Clock Signal From My USB Device As The Source For My Timed Loop? I would like to use a clock signal from my USB device as the source for my timed loop. I know that there are several timebases that are faster and/or more accurate than my computers 1kHz clock. When I specify the device as my source, I get an error saying this is not supported by my device. URL: http://digital.ni.com/public.nsf/allkb/0DB07AD09DD65AC58625741D007867DA

Acquiring On-Board Temperature from a PCI-6704 Static Analog Output Module How can I read the on-board temperature sensor of a PCI-6704 data acquisition (DAQ) device?The text below appears in the user manual, but it does not explain how to actually acquire the device temperature? The onboard temperature sensor measures the air temperature URL: http://digital.ni.com/public.nsf/allkb/B04ECBEA61188801862573E7006DD98B

Clearing the User-Accessible EEPROM on an NI-DAQmx Supported Device I need to clear all the user-accessible memory on my device for security reasons. I know that volatile memory loses its contents when the device is powered off, but non-volatile memory retains its contents. The EEPROM is the only non-volatile memory on NI-DAQmx supported devices. How do I URL: http://digital.ni.com/public.nsf/allkb/E6719B82A2C0C2EC862573B600165510

在带缓冲的事件边沿计数仅仅在计数值改变时才写进缓冲区 在M 系列板卡中，带缓冲的事件边沿计数仅仅在计数值改变时才向缓冲区中写数。如果我想对同样的计数值多次读取，我仅仅只能接收到第一次的值，其他读数均返回为空。但在 E 系列数据采集卡上是可以这样做的。 URL: http://digital.ni.com/public.nsf/allkb/39568E1A985033A048257393001F8181

How Do I Connect a Quadrature Encoder to NI ELVIS When Using an M Series Device? I am trying to use two angular quadrature encoders on an NI ELVIS with an M Series device using DAQmx in LabVIEW. The B terminals for the counters are inaccessible because they are set at RESERVED (ctr0) and SCANCLK (ctr1). These lines must be reassigned.

Creating a Delayed, Retriggerable and Finite Pulse Generator I want to perform a delayed, retriggerable, finite pulse train generation. When I generate a single finite pulse from a retriggerable counter (Fig. 1 - Delayed retriggerable single pulse), it behaves differently than generating a finite pulse train from a retriggerable counter (Fig. 2 - Delayed URL: http://digital.ni.com/public.nsf/allkb/204538A044431C9B86257377004EB952

DAQmxでアナログトリガソースとしてチャンネルを設定できないのはどうしてなのでしょうか。 アナログトリガをアナログ入力チャンネルに設定するとエラー-200265が起きてしまいます。 URL: http://digital.ni.com/public.nsf/allkb/CFCA8CE94D9E06A686257384000F620A
