Why Do the NI PXI-5600 NI-Tuner VIs Have a Span Input? There are some VIs in the NI-Tuner API that require a span (bandwidth) input, but the NI PXI-5600 downconverter has a fixed 20 MHz real-time bandwidth. URL: http://digital.ni.com/public.nsf/allkb/ACD900CD628D4EFA8625726600089F17

How Can I Maintain an Output Voltage After a Task has Stopped on an NI-4461? When I am outputting a signal on my NI-4461, I notice that the channel resets to zero volts after the DAQmx task is done. I would like it to maintain the last value that was output on the channel. Is this possible? URL: http://digital.ni.com/public.nsf/allkb/DC9D2AB6DFB1924E86257260000CC350

How Do I Know if My PXI Module is Supported in LabVIEW Real-Time? I am trying to use my PXI module in LabVIEW Real-Time and either it is not showing up in Measurement & Automation Explorer (MAX) or I am having difficulties using the module. Is it possible that my PXI module is not supported with LabVIEW Real-Time? Where can I find this information? URL: http://digital.ni.com/public.nsf/allkb/E2DAD2237DA72156862572430081BD49

MI和PXI的Microsoft VB 6.0的工具包 我正在Microsoft VB 6.0下写一个应用程序，将会使用到 NI模块化仪器和PXI产品．对于NI-Sync, NI-TCLK, NI-HWS没有VB 6.0的编程界面，我在VB 6.0里面应该怎样调用这些驱动呢？ URL: http://digital.ni.com/public.nsf/allkb/1F53E9759B686F8E48257228002552D6

我能分别触发NI 5102的两个通道吗？ 我能分别触发NI 5102的两个通道吗？换句话说，我想用一个触发源去分别触发NI 5102的两个输入通道。 URL: http://digital.ni.com/public.nsf/allkb/E2B07E13624654A94825720A003B9ED1

Microsoft Visual Basic 6.0 Wrappers for NI Sync, NI TClk, and NI HWS I am trying to write an application in Microsoft Visual Basic 6.0 that uses NI modular instruments and PXI products. There is no Visual Basic 6.0 programming interface available for NI-Sync, NI-TClk, and NI-HWS. How can I use these drivers from VB 6.0?

如何通过Traditional DAQ来使能DSA设备上的IEPE激励 我将NI 4472 DSA设备应用在多个应用中。有时要求在所有的通道上都连接4mA的IEPE加速度计，有时我只是用不需要激励的被动传感器，然而某些情况下我要将不同类型的传感器结合使用。按我所需地在每个通道上使能或者中止4mA激励的最佳方法是什么？ URL: http://digital.ni.com/public.nsf/allkb/F19E1521AF9845A648257203002180A6

在同一通道上使用模拟触发条件中的开始触发和参考触发 我使用的数据采集卡是PXI-4461，驱动是NI-DAQmx，我尝试在同一模拟通道上设置两个不同的触发条件：开始触发和参考触发，可是在配置过程中，我不能为不同的触发条件设置各自的触发沿类型，触发沿类型最终与参考触发的触发沿类型相同(最后配置参考触发)。■> URL: http://digital.ni.com/public.nsf/allkb/97EB9A14B2EB41F4482571FE0023E0A5
