Other Troubleshooting Tips
Here are a few tips for troubleshooting this device.
Noise from Power Supply
If you are experiencing relatively erratic measurements from the gator:microphone, it could be due to noise from your power supply. Double check that the power supply is clean, preferably with an oscilloscope; irregularities on the supply can be passed on to the outputs.
- Switch-mode power supplies often introduce oscillations in the power rails.
