Performance Analyzer Application

This application Performance Analyzer is a Serial interface based application, which communicates with Wireless Analyzer to demonstrate various features and capabilities of Atmel Transceivers.

Modules
	Range Measurement
	Performs the functionalities of Range measurement mode, Evaluate the Communication coverage of the transceiver.
	Serial Parser
	Handles all the serial input and output commands.
	Application Initialization Process
	Initializes the Performance Analyzer Application.
	Packet error rate measurement
	Handles the functionalities of Packet Error Rate Measurement(PER) Mode, User can set and get various paramters of Transceiver like Channel,Antenna Diversity,CSMA and do the Packet Error Rate Measurement.
	User Interface
	Handles all User interface related functions such as Button, Print,LED events.
	Peer Search Process
	Handles the functionalities of peer searching process.
