(1)	User port (Analog	This section provides user interface and CEX functions.
I/O)
(2)	Driver/Exciter	This section generates power at the designated output frequency
		to drive the main RF sections.
(3)	RF Amplifier	This section generates RF power.
(4)	RF Measurement	This section samples the output signal and sends it to the sensor
		electronics.
(5)	Digital	This section is the main processor and data acquisition section. It
	Controller	also provides host communications through an RS-232 port.
(6)	Sensor Electronics	This section detects RF samples and sends them to the
		microprocessor.
