PCI 6052E sample rate

Go to solution



I am using PCI 6052E, SCXI chassis 1001 and SCXI 1530 for my DAQ system. I am using Labview 8.6 and Traditional DAQ. 


I tried to set different scan rates. The maximum scan rate I can reach is around 100,000.  Once beyond 100, 000, there is an error message “the clock rate exceeds the board's recommended maximum rate”. I checked the maximum scan rate can be 333KS/s and the maximum internal clock can reach 20MHz. Why does this happen, Any idea? I am only using one channel from scxi 1530.

Have you seen this KnowledgeBase article?  You system will be limited by whichever component has the lowest maximum sampling rate, in this case that should be the 1530.

Thanks for reminding me this.


The maximum scan rate of scxi 1530 is 125Ks/second...I got 100, 000 from experiment, any idea about the difference?
