PXI-6608 Not Recognizing IRIG-B Signals For GPS Time I am using the example program that ships with LabVIEW, called 'GPS - Time N Software Events (NI-TIO).vi'. I connect my GPS receiver to the PXI-6608 so that the board will synchronize with GPS time, but the time displayed in the VI's front panel is not synchronized correctly. What is the problem?

Quadrature Encoder Counting By Two I have a quadrature encoder connected to my counter and it seems to be counting by two with every tick. In addition, at certain values the count register will appear to respond out of order as if the count back-tracks for a couple of ticks.

ロータリエンコーダの各ティックに対してカウンタが2つずつカウントする問題について。 現在カウンタに接続されているロータリエンコーダの各動作でカウンタのカウント値が２ずつ変化しています。また、時々、エンコーダが回っているにもかかわらずカウント値が変化しません。この原因は何でしょうか？ URL: http://digital.ni.com/public.nsf/allkb/76DFC69178E8FAA1862570BC000E511C

Why Do I See an Incorrect Output on My NI 6624? The NI 6624 counter/timer board has isolated outputs and need to be driven by an external power supply. An external power supply can have any voltage in the range of 5V to 48V. URL: http://digital.ni.com/public.nsf/allkb/1912FEF6820833BF86256E2A0003365A

Why Is My DAQ-STC Counter Returning a -2.5 to 2.5 Signal? I am using a scope to read the output of my DAQ-STC counter. I know that the signal should be TTL, but I am reading -2.5 to 2.5 volts with my scope. Why is this? URL: http://digital.ni.com/public.nsf/allkb/D76EFF36FAAFAEE786256DDE00545A76

Glitches in Signal Causing Incorrect Event Counting or Position Measurement I am doing a position measurement and am not getting the results that I am expecting. When looking at the signal from the encoder, I can see that signal is not clean and the glitches are causing an invalid measurement. What can I do to remove these glitches?

Why am I Getting a Wrong Count From the 80 MHz Timebase on My PCI-6602? When I run Count Buffered Edges (NI-TIO).vi that ships with LabVIEW, I notice that my count is not 4 times larger when using the 80 MHz timebase when compared to the 20 MHz timebase.

데이터 수집 DAQ-STC 카운터 칩에서 수집할 수 있는 시그널 레이트는 어떻게 됩니까? DAQ-STC 카운터를 사용하고 있는데 다른 작동에서 수집 속도에 대한 벤치마크를 알고 싶습니다. finite 또는 continuous buffered count events처럼 DAQ-STC 성능 작동은 얼마나 빠릅니까? URL: http://digital.ni.com/public.nsf/allkb/38420320A7F5EA2886256E8C0042F327

Why Does My PXI-6608 Timebase Seem Incorrect? For PXI-6608 devices shipped before October 12, 2000, the calibration data was not being written to the right location. At the time of calibration, the frequency of a PXI-6608 that meets specifications is adjusted to within 0.1 Hz of 10 MHz. For devices shipped before October 12, 2000, some units URL: http://digital.ni.com/public.nsf/allkb/255F41C46B1FD3BF862569820078DD60
