CDMA Operating Frequency Programming Information – North American PCS Bands Introduction Programming of each of the BTS BBX2 synthesizers is performed by the BTS GLIs via the CHI bus. This programming data determines the transmit and receive transceiver operating frequencies (channels) for each BBX2. 1900 MHz PCS Channels Figure D-1 shows the valid channels for the North American PCS 1900 MHz frequency spectrum.
CDMA Operating Frequency Programming Information – North American Bands – continued Calculating 1900 MHz Center Frequencies Table D-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: TX = 1930 + 0.05 * Channel# Example: Channel 262 TX = 1930 + 0.05*262 = 1943.

Appendix E: PN Offset Programming Information PN Offset Background All channel elements transmitted from a BTS in a particular 1.25 MHz CDMA channel are orthonogonally spread by 1 of 64 possible Walsh code functions; additionally, they are also spread by a quadrature pair of PN sequences unique to each sector. Overall, the mobile uses this to differentiate multiple signals transmitted from the same BTS (and surrounding BTS) sectors, and to synchronize to the next strongest sector.
Appendix E: PN Offset Programming Information – continued – If you are using a Qualcomm mobile, use the I and Q values from the 13 chip delay table. – If you are using a mobile that does not have the 1 chip offset problem, (any mobile meeting the IS–97 specification), use the 14 chip delay table. IMPORTANT * If the wrong I and Q values are used with the wrong FineTxAdj parameter, system timing problems will occur.

Introduction Purpose This procedure is a guide to expanding your system with multiple carriers while the system remains in service. This procedure also allows you to perform on site maintenance (replace defective boards and recalibrate) while the remainder of the site stays in service. Motorola recommends that you perform this procedure during a maintenance window. This procedure cannot be performed on BTSs with 4–to–1 combiners. The procedure can only be performed on one side of the BTS at one time.
Power Delta Calibration Power Delta Calibration Introduction The In–service calibration procedure has several differences from a normal calibration procedure. One of these is the use of a spectrum analyzer instead of a power meter to measure power. Power meters are broadband measurement devices and cannot be used to measure power during In–service Calibration since other carriers are operating. A spectrum analyzer can be used because it measures power at a given frequency.
