Making Measurements

Advanced Features

	Advanced Features
Other Screens	The screens mentioned in this section are not necessary for simple measurement of
	mobile phones as the work is done by the functions mentioned previously. However,
	the advanced user may ﬁnd it worthwhile to know what these screens are and what
	they are capable of doing.
	• RF Generator/RF Analyzer - this screen controls the Agilent 8922M/S RF
	generator and RF analyzer. This screen can be accessed by pressing the following
	keys:
	•			,				, (RFG/RFA)
			SHIFT			CELL CNTL

	• MS Information - the MS INFO (Mobile Subscriber Information) screen gives
	you access to the information about the mobile phone itself. A Location Update
	can be verified from this screen. This screen can be accessed by pressing:
	•			,				, (MS INFO)
			SHIFT		CELL CONFIG

•Cell Configuration - the CELL CONFIG screen gives you access to the control parameters for the configuration of the cell. This screen can be accessed by pressing:

• CELL CONFIG

•Cell Control 2 - gives you the capability to control the additional cell parameters. This screen is relevant in the set up of a call. This screen can be accessed by highlighting the More field in any main screen and selecting CELL CNTL2.

•Hopping - the hopping screen allows you manual control of the hopping frequencies. This feature is only available in the Agilent 8922G compatibility mode.

•Logging - the logging screen allows control over the Protocol Interface port on the rear panel (option 003). To access this screen, highlight More and select

LOGGING.

•Configuration - the configuration screen is a full instrument control screen which allows you to set up the Agilent 8922M/S. Screen set up, compatibility mode, radio type as well as other miscellaneous pieces of information are contained on this screen. To access this screen, highlight More and select

CONFIG.

•I/O Configuration - the I/O configuration screen allows you to set up the general interface of the instrument, such as printer options. This screen can be accessed by highlighting the More field in any main screen and selecting I/O CONFIG.
