The R2008C is an expansion of the R2001C which extends its testing capability to include the unique requirements of cellular radio systems. Any existing R2001C communications system Analyzer can be modified to an R2008C. With the modification, all of the capability of the R2001C is retained with the cellular test sequences being added as an extension of the tone memory display. Cellular test capability in the R2008C includes performance verification for both the digital signaling and the RF transceiver aspects of the cellular radio. In the cellular test mode, the Analyzer imulates the basic aspects of the central cell site. It provides all of the signaling required to allow both call origination and call reception testing on the cellular transceiver. In addition, once the voice path is established, the R2008C can then be used to simulate cell site to cell site handoffs, to control the transmitter power level, and to execute performance tests normally associated with a transciever.
