+@brief   E4000 tuner module declaration
+
+One can manipulate E4000 tuner through E4000 module.
+E4000 module is derived from tuner module.
+
+
+
+@par Example:
+@code
+
+// The example is the same as the tuner example in tuner_base.h except the listed lines.
+
+
+
+#include "tuner_e4000.h"

+	TUNER_MODULE          TunerModuleMemory;
+	BASE_INTERFACE_MODULE BaseInterfaceModuleMemory;
+//	I2C_BRIDGE_MODULE     I2cBridgeModuleMemory;
+
+	unsigned long BandwidthMode;
+

+		CRYSTAL_FREQ_16384000HZ,			// Crystal frequency is 16.384 MHz.
+		E4000_AGC_INTERNAL					// The E4000 AGC mode is internal AGC mode.
+		);
+
+
+
+
+
+	// Get E4000 tuner extra module.
+	pTunerExtra = (T2266_EXTRA_MODULE *)(pTuner->pExtra);
+
+
+
+
+
+	// ==== Initialize tuner and set its parameters =====
+

+
