1)Ensure that all external power sources are set to OFF.
2)Connect an external regulated power supply set to 5 V to the module VDD
-and GND pins, taking care to observe marked polarity.

7)Verify correct voltage and input polarity and set the external power supply to ON.
The EVM should begin operation.
8) Adjust the signal source level as needed.
