Example 3
Using Processing Power for FFT: This commands the
LSA1000 to perform FFT (Fast Fourier Transfer) on the captured
waveform and transfer FFT result to the host PC.
Requirement
Sample Rate = 1.5GS/s
Capture Time = 50us
Number of Points = 75,000
LSA1000 Settings
Sample Rate = 2GS/s
Time per Div. = 5us
Memory Size = 100K
