You can configure the fast Fourier transform (FFT) channel to perform a 16K-point fast Fourier transform on the signal.
Use the following settings to configure the FFT channel.
|Status||Enables or disables fast Fourier transform on the source channel.|
|Source channel||Source channel on which you want to perform fast Fourier transform.|
|Window||Time-domain window to apply to the signal.|
|Start frequency||Frequency at the extreme left of the horizontal axis.|
|Stop frequency||Frequency at the extreme right of the horizontal axis.|
|Center frequency||Frequency that is at the center of the horizontal axis.|
|Span||Range between the start frequency and the stop frequency.|
|Reference level||Maximum expected power of the input signal. The Oscilloscope automatically sets Reference level based on the value of Volts/Div.|
|Resolution bandwidth||The horizontal scale.|
|Record length||Range of the X axis on the time domain graph.|
