7 Appendix A - Establishing Absolute GSM BCH Power Level 81
Appendix A - Establishing Absolute GSM BCH Power Level Procedure Procedure The following procedure can be used for determining the absolute GSM BCH peak power level. The GSM BCH power level is the output from the RF In/Out port along with the TCH. This output is used to synchronize calls when switching from E-GSM900 to DCS1800 (Dual Band mode). It is assumed that the operator is familiar with operating the HP/Agilent 8922 Multi-Band Test System and HP/Agilent 8560 Series Spectrum Analyzers.
