					0=Normal	TSI*		arguments)
					1=TX Spectrum Invert	TSI#
						TSI$
					Example: TSI=0 (Normal)	TSI^
						TSI@
TX Scrambler	TSC=		1 byte, value of		Command or Query	TSC=	TSC?	TSC=x
			0, 1, 2		Tx Scrambler state: where:	TSC?		(see description of
					0=Off	TSC*		arguments)
					1=ON (Default scrambler type)	TSC#
					2=ON IESS-315 (Turbo Only)	TSC$
						TSC^
					Example: TSC=1 (Scrambler one)	TSC@

TX Carrier	TXO=		1 byte, value 0	Command or Query		TXO=	TXO?	TXO=x
State			though 4	TX Carrier State, where:		TXO?		(see description of
				0=OFF due to front panel or remote control command		TXO*		arguments)
				1=ON		TXO#
				2=RTI (Receive/Transmit inhibit)		TXO$
				3=OFF due to EXT H/W TX Carrier Off command (not a		TXO^
				valid argument when used as a command)		TXO@
				4=OFF due to BUC warm up delay (not a valid argument
				in a command format)
				Example: TXO=1 (TX Carrier ON)

TX Power Level	TPL=		4 bytes		Command or Query	TPL=	TPL?	TPL=xx.x
					TX Output power level between -5 and –25 dBm (minus	TPL?		(see description of
					sign assumed)	TPL*		arguments)
						TPL#
					Example: TPL=13.4	TPL$
					(Command not valid in AUPC mode)	TPL^
					Note: When output power level is enabled: Power level	TPL@
					Note: When output power level is enabled: Power level
					configuration is not allowed. Response will be TPL*. The
					response to the query TPL? Will be the adjusted levelled
					value.
