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.

- 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.

- Enter a Frequency value between 0.5 Hz and 200 Hz.
- 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.
- Click OK to continue.
The waveform will continue until you select Off from the Waveform
pop-up menu in the Analog Out Menu.
