Driving Loads with the PCI/PXI-6704 Gives Inconsistent Results I am doing current output to drive a load with the PCI/PXI-6704, I am expecting to see 5 volts across the load. When I measure the resulting voltage, it seems to rail and/or fluctuate between 0 and 10 volts. What is going on? URL: http://digital.ni.com/public.nsf/allkb/C3EABE7C30FA253A862572C30072F6A8

为什么PCI-6733输出的频率是振荡的？ 我试图用PCI-6733产生一个频率为10682Hz的方波，更新率为800kS/s。为什么输出信号的频率是振荡的？为什么不能获得一个稳定频率的输出？ URL: http://digital.ni.com/public.nsf/allkb/8ACD3E450185EF3E482572B2003F9A81

Is the PCI/PXI-6723 Compatible with the BNC-2115? I have a PCI/PXI-6723 with two 68-pin connectors in the front. I see that Connector 0 can connect to a BNC-2110 becuase it has pins for digital, PFI, and counter lines, along with analog output channels 0 through 7. I see that Connector 1 has pins for analog output channels 8 through URL: http://digital.ni.com/public.nsf/allkb/9F83E6261786CFDB8625727B0020E13D

Why Does the Frequency Oscillate in the Output of My PCI-6733? I am trying to generate a square wave of 10682 Hz with an update rate of 800 kS/s on the PCI-6733. Why does the frequency of the output signal oscillate? Why am I not getting a stable frequency output? URL: http://digital.ni.com/public.nsf/allkb/677C0219BFC9CE2886257252002CE600

Oscillating Analog Output Signal from PCI-6704 I am using a PCI-6704 board to drive my external circuit. When I output 5 volts to my circuit, the output signal measures 4.4 volts. If I measure the value of my analog output signal when the card is not connected to my external device, I measure the expected 5 volts. Why do I see a URL: http://digital.ni.com/public.nsf/allkb/B0DA63E0671E61A086257210007DD4D5
