 when connected to the 

LabQuest Audio Out port. The Power Amplifier is used 
to create waveforms with up to 10 V amplitude and 
currents of 1 A. 

Select the desired output (AC or DC). DC output levels 
are limited to 0.2 V steps. AC waveforms include sine, 
square, sawtooth, and ramps. Select an amplitude and 
frequency using the controls. The frequency can be 
changed by factors of two using the ÷2 and ×2 buttons. 

 

 Sound Recorder  

You can use the Sound Recorder app to record and 
replay short audio clips. The clips can be saved and 
replayed as needed.
