PXI-4110 Power Supply를 이용한 Bipolar Voltage Source 이용이 불가능한 이유 PXI-4110 DC Power Supply를 가지고 있고, 그것의 ch0, ch1을 이용하여 bipolar voltage source로 사용하려고합니다. 제가 DMM을 이용하여 전압을 측정하면 잘 돌아가는 것처럼 보이지만, 실제 load를 연결하면 전압의 변화가 예측하기 어려운 식으로 돌아갑니다. 무슨 일이 일어■> URL: http://digital.ni.com/public.nsf/allkb/E3B66BB6675B4054862572D6002F9C5A

Using the PXI-4110 Power Supply to Create a Bipolar Voltage Source I have a PXI-4110 DC Power Supply and I'd like to configure it to be used in a bipolar setup with channels 0 and 1. When I attach a DMM to measure the differential voltage it appears to work, but connecting a load causes the voltage level to change or drop unexpectedly. Why does this happen?

自校准和外部校准的区别是什么？ NI Home This Document is not yet Rated Rate this Document 自校准和外部校准的区别是什么？ 硬件: Modular Instruments, Multifunction DAQ (MIO) 问题: 自校准和外部校准的区别是什么？ 解答: 校准是很重要的，因为任何一个特定的模数转换器的性能都会随着温度、输入电压、时间或其它因素的变化而变化。因此，当校准DMM或者DAQ板卡的时候，就需要考虑上述两种情况。 URL: http://digital.ni.com/public.nsf/allkb/BA55B76C85D4210A8625723900367377

Can I Synchronize Different Types of DSA Devices at Different Rates? I have a 4462 and a 4472. I would like these two devices to be synchronized together but to acquire data at different rates. Is this possible? URL: http://digital.ni.com/public.nsf/allkb/83C82B37411D837286257221006D5288

Decreasing the digits of resolution on my DMM causes incorrect readings when measuring coil resistance. I am measuring a coil resistance. When I set my DMM to measure at 6.5 digits of resolution my readings are all good. When I read at 5.5 Digits my readings are off by +/-5 Ohms. When I measure at 4.5 Digits my readings are off by about +/-10 Ohms. When I am measuring resistance in the 50 URL: http://digital.ni.com/public.nsf/allkb/D99D0C3EE1E6846086257206003C0E6F

Simple Troubleshooting Steps to Improve Scope Accuracy I am aware of the DC and AC accuracy specifications listed for my NI High-Speed Digitizer.
