Thanks for your reply. I'll check out the STFT function in LabVIEW.
Unfortunately, I can't attach the tdms file in the forum as it isn't a valid file format for the forum.
Here's the error from the forum.
- The file does not have a valid extension for an attachment. jpg,gif,txt,xls,vi,zip,doc,llb,pdf,png,seq,c,h,cpp,cs,vb,ini,gz,ctl,scr,ico,tar,z,uir,vit,wsp,tsw,rtf,lvproj,xctl,lvlib,cfg,ppt,pps,lks,spy,bld,lep,xlt,xltx,dot,dotx,docx,xlsx,cap,tui,csv,seproj,vip,ogp,vipc,ms10,ms11,ewprj,log,vix,lvprojx are the valid extensions.
But you can obtain a sample using the record.vi that I've attach in the first post. It generates a random waveform and records them into a tdms file to allow me to test my VI.
