FFT Channel
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.
| Setting | Description |
|---|---|
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. |
| Display | Description |
|---|---|
| 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. |
