CDMA Operating Frequency Programming Information 68P64115A18–1 CDMA Operating Frequency Programming Information Introduction Programming of each of the BTS BBX synthesizers is performed by the BTS GLI2s via the Concentration Highway Interface (CHI) bus. This programming data determines the transmit and receive transceiver operating frequencies (channels) for each BBX. 1900 MHz PCS Channels Figure E-1 shows the valid channels for the North American PCS 1900 MHz frequency spectrum.
68P64115A18–1 CDMA Operating Frequency Programming Information Calculating 1900 MHz Center Frequencies Table E-1 shows selected 1900 MHz CDMA candidate operating channels, listed in both decimal and hexadecimal, and the corresponding transmit, and receive frequencies. Center frequencies (in MHz) for channels not shown in the table may be calculated as follows: S TX = 1930 + 0.05 * Channel# Example: Channel 262 TX = 1930 + 0.05 * 262 = 1943.10 MHz S RX = TX – 80 Example: Channel 262 RX = 1943.

Introduction 68P64115A18–1 Introduction Purpose This procedure is a guide to performing calibration of new BTS expansion carriers while the system remains in service. This procedure also supports BTS recalibration following replacement of RF chain components while the remainder of the site stays in service. Motorola recommends performing this procedure during a maintenance window. This procedure cannot be performed on BTSs with 2–to–1 combiners.
Power Delta Calibration 68P64115A18–1 Power Delta Calibration Introduction The ISC procedure has several differences from a normal calibration procedure. One of these is the use of a spectrum analyzer/communications test set instead of a power meter to measure power. Power meters are broadband measurement devices and cannot be used to measure power during ISC because other carriers are operating. A spectrum analyzer can be used because it measures power at a given frequency.
