USB5133

I am using the attached vi to collect data.

 

Sampling frequency is 100MHz. Using analog edge trigger. The signal is pulse waveform.

Every pulse need to collect 512 points.

 

I made a test, using a signal generator generate a 100kHz sine wave. If the 5133 is fast enough, it should collect 100k wave/S. But it can only collect around 140wave/S. I tried to make wave collection shorter as 256 points. But it still only can collect around 140 wave/S, too slow.

 

 

Any suggestion? (my pc is quite new)

Try playing with the min record lenght on the 2nd subvi of your vi.
