Agilent Technologies 8922M/S Operating Modes

This section details the procedures necessary to control the Agilent 8922M/S and GSM mobile phone in each of the main operating modes. It is recommended that you read this section before attempting the “Measurements” section.

	The Agilent 8922M/S GSM Test Sets have three main modes of operation, these are:
	•	ACTIVE CELL
	•	TEST MODE
	•	CW GENERATOR
Active Cell	The ﬁrst mode is the default mode and conﬁgures the Agilent 8922M/S as a GSM
	Base Station emulator. This allows calls to be made from the Agilent 8922M/S to
	the mobile phone and vice versa. Measurements can then be made to verify the
	mobile phone’s performance.
Test Mode	This mode is used when measurements need to be made on the mobile phone
	without a call being set up.
CW Generator	This mode conﬁgures the Agilent 8922M/S as a standard Continuous Wave (CW)
	Signal Generator. This is used for test applications that require an unmodulated RF
	carrier.
