IS-2000 Test Operating Mode
Last updated: October 28, 2004
When the test set is in IS-2000 Test operating mode (as opposed to Active Cell operating mode) it is necessary for the mobile station under test to be capable of independently performing operations that normally occur through over-the-air signaling. This capability is referred to as test mode and is usually accomplished using commands which are sent to the mobile station from a system controller (usually a personal computer) through a proprietary digital interface. For more details on IS-2000 Test operating mode, see the product note:
The
Agilent Technologies E1962A IS-2000 Test Mode Requirements for Mobile Stations
product note is also applicable to the E1962B test application with the E5515C test set in IS-2000 Test operating mode.
To make measurements on the reverse channel in test mode, the mobile station must first synchronize to the test set's forward pilot channel and demodulate the sync and paging channels. This is consistent with normal system acquisition procedures and results in the mobile station reaching the mobile station idle state. In active cell operating mode, the mobile station at this point would autonomously perform a power-up registration after entering the idle state. A call could then be initiated, using over-the-air call processing, and the fundamental channel would be established and maintained according to the applicable message protocol.
However, in test mode the test set and mobile station are directed to the same FCH (fundamental channel) by the system controller or through manual user interfaces without over-the-air call processing.
Forward CDMA channels available in test mode
In test mode, the test set can be configured to transmit a forward channel that emulates a base station operating in radio configuration (RC) 1, 2, 3, 4 or 5. See
