Very nice!! A tip for anyone wishing to use the new 1024 point FFT (or the old one for that matter)... Update rate as set in Timer1.Timer should be according...
I'm having the same problem as jr_gulbranson, using version 3 with a DI- 194RS. I'm using Delphi, but the same thing happenswith the VB samples that come with...

If your PC is fast enough, setting a higher updating rate actually shows the frequency transition in greater detail ... one ... formula... ... FFT ... and...
Nope... the detail in the Frequency Domain is not relative to the speed of the PC. It is only relative to the Windaq samplerate and the Windows Timer...
I didn't mean to increase the resolution through higher update rate. What I meant is when you overlap the data in time domain for FFT, you can actually make...

Ahhh... yes! Smoothing! I did not think of that but running at higher updates definitely does smooth the spectral response. I usually think of it as "smearing"...
