Bay Level Offset Calibration Introduction Calibration compensates for normal equipment variations within the BTS and assures maximum measurement accuracy. RF Path Bay Level Offset Calibration Calibration identifies the accumulated gain in every transmit path (BBX2 slot) at the BTS site and stores that value in the CAL file. The BLOs are subsequently downloaded to each BBX2. 3 Each receive path starts at a BTS RX antenna port and terminates at a backplane BBX2 slot.
Bay Level Offset Calibration – continued TX Path Calibration The TX Path Calibration assures correct site installation, cabling, and the first order functionality of all installed equipment. The proper function of each RF path is verified during calibration. The external test equipment is used to validate/calibrate the TX paths of the BTS. WARNING Before installing any test equipment directly to any TX OUT connector you must first verify that there are no CDMA channels keyed.
Bay Level Offset Calibration – continued BLO Calibration Data File During the calibration process, the LMF creates a calibration (BLO) data file. After calibration has been completed, this offset data must be downloaded to the BBX2s using the Download BLO function. An explanation of the file is shown below.

CDMA Operating Frequency Programming Information – North American PCS Bands Introduction Programming of each of the BTS BBX2 synthesizers is performed by the BTS GLI2s 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: S 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 IMPORTANT * If the wrong I and Q values are used with the wrong FineTxAdj parameter, system timing problems will occur. This will cause the energy transmitted to be “smeared” over several Walsh codes (instead of the single Walsh code that it was assigned to), causing erratic operation. Evidence of smearing is usually identified by Walsh channels not at correct levels or present when not selected in the Code Domain Power Test.
