-** Name: MT2063_Tune
-**
-** Description: Change the tuner's tuned frequency to RFin.
-**
-** Parameters: h - Open handle to the tuner (from MT2063_Open).
-** f_in - RF input center frequency (in Hz).
-**
-** Returns: status:
-** MT_OK - No errors
-** MT_INV_HANDLE - Invalid tuner handle
-** MT_UPC_UNLOCK - Upconverter PLL unlocked
-** MT_DNC_UNLOCK - Downconverter PLL unlocked
-** MT_COMM_ERR - Serial bus communications error
-** MT_SPUR_CNT_MASK - Count of avoided LO spurs
-** MT_SPUR_PRESENT - LO spur possible in output
-** MT_FIN_RANGE - Input freq out of range
-** MT_FOUT_RANGE - Output freq out of range
-** MT_UPC_RANGE - Upconverter freq out of range
-** MT_DNC_RANGE - Downconverter freq out of range
-**
-** Dependencies: MUST CALL MT2063_Open BEFORE MT2063_Tune!
-**
-** MT_ReadSub - Read data from the two-wire serial bus
-** MT_WriteSub - Write data to the two-wire serial bus
-** MT_Sleep - Delay execution for x milliseconds
-** MT2063_GetLocked - Checks to see if LO1 and LO2 are locked
-**
-** Revision History:
-**
-** SCR Date Author Description
