Sweep (Log) with On/Off Switch

The Sweep (Log) block generates a sinewave that sweeps from a start frequency to an end frequency. The sweep rate is determined by the number of sweep steps and cycles per step.

Enter the desired start and stop frequency and step size using the edit controls:

• Start Freq
  • The frequency at which to begin the sweep.
• Stop Freq
  • The frequency at which to end the sweep.
• # Steps
  • Determines the number of steps in the sweep.
• # Cycles/Step
  • Determines the number of the cycles (sine wave cycles) in each step.
• On/Off switch
  • Starts the sweep

The graph below shows a sweep from 10 Hz to 300 Hz achieved in four steps with two cycles in each one.
