The Power Amplifier (PAMP) is, as the name signifies, an amplifier. It does not include its own signal generator, rather simply amplifies an existing signal. There are several options for creating a signal to drive the Power Amplifier:

1. LabQuest 3 (LABQ3), LabQuest 2 (LABQ2), or LabQuest (LABQ)
Using a LabQuest’ s Power Amplifier App is the best option. Connect the Power Amplifier “Audio In” to the LabQuest Audio Output via the included stereo cable, launch the Power Amplifier app, and choose your desired settings (waveform, amplitude, frequency, etc.).

2. LabPro (LABPRO) and Logger Pro software
The LabPro interface, when combined with our Logger Pro software, can create a signal for the Power Amplifier. Connect the LabPro’s CH4 to the Power Amplifier using the included BTA-BTA cable, launch Logger Pro, and open the Sensor Setup window. Click on the Ch4 icon, select “Analog Out”, and choose your desired settings (waveform, amplitude, frequency, etc.).

3. PC/Mac Computer and Power Amplifier Function Generator software
Our free Power Amplifier Function Generator software can use your computer’s sound card to create a signal for the Power Amplifier. Connect your computer to the Power Amplifier via the included stereo cable, launch the software, and choose your desired settings.

TWO NOTES:

  • -Sound cards vary greatly from one computer to the next, so this does not work on all computers.
  • The Power Amplifier Program will not work on Mac OS 11.

4. Stand-alone function generator
The Vernier Power Amplifier can be used with most function generators. Connect the function generator to the 3.5 mm input using a mono connector only. A stereo connector may enable the PWM features of the Power Amplifier with undesirable results. When used with this input, the Power Amplifier applies a factor of ten gain to the input signal. The input is DC-coupled.

For full connection and usage details, see the Power Amplifier user manual: Specifications and User Guide.
