PAGE 35
Test Equipment 68P09255A57-2 1 Test Cable Calibration Equipment test cables are very important in optimization. Motorola recommends that the cable calibration be run at every BTS with the test cables attached. This method compensates for test cable insertion loss within the test equipment itself. No other allowance for test cable insertion loss needs to be made during the performance of tests. Another method is to account for the loss by entering it into the LMF during the optimization procedure.
PAGE 36
Test Equipment 68P09255A57-2 1 - This solution passes only the three minimum electrical connections between the LMF and the GPIB interface. The control signals are jumpered as enabled on both ends of the RS-232 cable (9-pin D). TX and RX signals are crossed as null modem effect. Pin 5 is the ground reference. - Short pins 7 and 8 together, and short pins 1, 4, and 6 together on each connector.

Adjusting for loss 68P09255A57-2 Adjusting for loss 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 (BBX slot) at the BTS site and stores that value in the CAL file. The BLOs are subsequently downloaded to each BBX. Each receive path starts at a BTS RX antenna port and terminates at a backplane BBX slot.

PN Offset 68P09255A57-2 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.

Intra-Cabinet Cabling 68P09255A57-2 MPC Functional Description The MPC card provides (see Figure H-15) low-noise amplification for all RX path signals. The low noise, high gain design improves frame RX sensitivity and overcomes the splitting loss in the receive path. DC voltages are monitored on the RF devices and regulators and are used to generate hard and soft alarms. The MPC is not redundant at the card-level, but includes dual-path amplifiers which provide soft-fail redundancy for all sectors.
