pci6143采集信号

[Djun]

大家好！请问pci-6143可以采集双极矩形电压吗？ 可以用pci-6143采集板采集交流电压吗？ 还是单通道采集的电压信号必须是单向的（电压均为正或者为负）

pci-6143采集直流电压信号比采集交流电压信号更稳定吗？采集直流电压比交流电压的好处有哪些呢？

Hi everybody ! Can the pci-6143 collect bipolar rectangular voltage? Can I use the pci-6143 acquisition board to collect AC voltage? Or the voltage signal collected by a single channel must be unidirectional (the voltage is positive or negative)

Is the pci-6143 more stable than acquiring an AC voltage signal? What are the benefits of collecting DC voltage than AC voltage?

Hi djun,

Please read the datasheet of the PCI-6143: you can measure signals with an ±5V input range.

Is the pci-6143 more stable than acquiring an AC voltage signal?

That question makes no sense to me…

What are the benefits of collecting DC voltage than AC voltage?

There is no "benefit": a DC signal is just a special case of a (more generic) AC signal.

Thank you very much, the best wishes to you.
