Why Do I Get Error -89125? When I try to access the trigger lines on my device, I get the following error.Error -89125 'Device not configured'.Why does this error occur? URL: http://digital.ni.com/public.nsf/allkb/281704A664FB80BC862572700001410E

'Device not found' or 'Invalid Output Mode' Error When Using PXI-5402 in Arbitrary Waveform or Arbitrary Sequence Mode My PXI-5402 will not allow me to use the NIFGEN Arbitrary Function Generator Express VI in LabVIEW. It reports 'Device not found'. The card works fine with the FGEN SOFT FRONT PANEL and it also works fine in LabVIEW when using frequency lists for generating various waveforms. However, examples URL: http://digital.ni.com/public.nsf/allkb/69D980AB071A1E84862572600005E475

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

我可以用一个触发信号，一次序列的方式重复触发整个任意波形序列嗎？ 我希望用数字信号去触发整个任意波形序列，並且等待到下次触发信号来时再次重复整个动作。我应该用哪种触发模式？ URL: http://digital.ni.com/public.nsf/allkb/32274C416BB5319B4825723E000C6956

NI-5404 頻率產生器 Duty Cycle 之解析度與準確性 當使用 NI-5404 頻率產生器產生特定 Duty Cycle 的時脈輸出時，其解析度與準確性為何? URL: http://digital.ni.com/public.nsf/allkb/332732EF826F8D5A8625735D001C4E75

Why is the Amplitude of the NI 54xx's Output Signal Twice as Large as the Setting in the NI-FGEN? I am using a TDS1002B oscilloscope to measure the output signal of a NI PXI-54xx. I found the measured signal was twice as large as the setting in the NI-FGEN. Why is the amplitude twice the setting and how do I correct for this?

¿Por qué la Amplitud de la Señal Generada en el NI 54XX’s es el Doble de la Especificada en NI-FGEN? URL: http://digital.ni.com/public.nsf/allkb/03E92E4982439B918625747600019E47

為什麼 NI 54xx 的輸出訊號振幅是我在 NI-FGEN 設定的兩倍? 我使用 TDS1002B 示波器來量測 NI PXI-54xx 的輸出訊號。我發現量到的訊號是我在 NI-FGEN 上設定的兩倍。為什麼振幅會是設定的兩倍，我要怎麼改正? URL: http://digital.ni.com/public.nsf/allkb/D083647524F712BF8625749E0011A004

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

Effects of Offset on Waveform Resolution Using NI-5401 Function Generator How does adding an offset affect the resolution of a waveform generated with the NI-5401 Function Generator? URL: http://digital.ni.com/public.nsf/allkb/71FDC1F044D0CE26862571F800779DD7
