Which harware should I select (PXI or CompactRio) for high sampling rate acquisition

Hi all,

 

I would like to acquire some signals with high sampling rate (1 MHz and above) and save the data.

Which hardware should I select (PXI or Compact Rio)? 

For PXI, I read that we can select different multi-function data acquisition card for different sampling rate, which includes card with high sampling rate.

How about Compact Rio? From what I understand, the sampling rate depends on the sampling rate of module?

Please give some advice.

 

Thank you. Smiley Happy

Can you explain a little more about what you're acquiring? How many channels? What you intend to do with the data?


A CompactRIO can handle 1MHz, but if you're acquireing from 16 channels and intending to process the data as well as stored it, then you'll probably want a more powerful PXI.

Hi Thoric,

I'm planning to acquire the vibration and acoustic emission signals, 4 channels, I intended to acquire and store the data over a period of time.

Is the 1 MHz simultaneous sampling? What is the max data storage for Compact RIO and PXI?

Btw, what is the main difference between Compact RIO and PXI?

Thanks for helping. Smiley Happy
