Multi sample FFT in Flexrio 7976 and VST

[Usama555]

Hello, I am trying to compute multi sample FFT for my signal processing applications. I am using VST-5840 and trying to access data in Flexrio 7976 through p2pFIFO(8 samples/input). I am spiting the I & Q then feeding the array to Labview FFT core configured as continuous input and M interval output indexes(1024pts), At host side I am computing magnitude and doing decimation and plotting the results. But the problem is that my magnitude is not as that is required means maximum at consecutive 4,5 bins. Rather my magnitude is distributed over the entire band and I am getting 4 higher peaks and 4 lower peaks. It means my data is not continuous or if aligned/unpacked?

Why are you using the FlexRIO?  The FPGA onboard the 5840 is faster.

I need implement my algorithm in FPGA. If i want to do that in 5840 FPGA, then it needs to change the image of VST which is not suitable.

We would appreciate if you can provide us a little bit more context of the application

Helo all,

     I am using FPGA 7976 and Second generation VST 5840 for different application, currently I'm using Labview 2015 and facing driver problem so please suggest me whether VST support Labview 2018 or not and what are all the required drivers for VST other than RFSA,RFSG,RFmx..???

Hello Ganesh,

What versions of the RFSA, RFSG, and RFmx drivers do you currently have installed?

What behavior is indicating there are currently driver issues?

Are you seeing any error messages or numbers in LabVIEW or NI MAX?

Best,
