Analog Out

The Analog Out feature allows you to command Channel 4 of LabPro to output an analog signal in a number of different patterns. Among other applications, it can be used to study harmonic oscillation in strings and LRC circuit response.

Call up this window by clicking on Channel 4 from the Sensor Setup dialog and selecting Analog Out.

  1. From the Waveform pop-up, select one of the waveform types (DC, Ramp Up, Ramp Down, Triangle, Square, or Sine). A symbol representing the waveform will be displayed below Channel 4 of the LabPro dialog.      
  1. Enter a Frequency value between 0.5 Hz and 200 Hz.
  1. Enter the Amplitude of your selected waveform.  Type a number between 0 Volts and 4 Volts.
          User parameters are names for variables that you can control. Check the box next to Create User Parameters to add a Parameter Control to your page.
  1. Click OK to continue.

The waveform will continue until you select Off from the Waveform pop-up menu in the Analog Out Menu.
