Add the following controls and indicators, as shown in the following figure:
- Decimation—Specifies how much decimation is performed on the analog input signal. This control determines the maximum bandwidth of your signal.
- NCO frequency—Specifies the center frequency for the analog input waveform.
- Frequency—Specifies the frequency at which to generate a sine tone. This tone can serve as a test signal for the simple spectrum analyzer.

- Divide the decimation rate value by 100M, which is the default Sample Clock rate of the ADCs, and wire the output to the dt input of the Build Waveform VI.
