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.

In–Service Calibration In–Service Calibration IMPORTANT * This feature does NOT have fault tolerance at this time. The system has no safe–guards to stop you from doing something that will take the BTS out of service. If possible, perform this procedure during a maintenance window. Follow the procedures in this section precisely, otherwise the entire BTS will most likely go OUT OF SERVICE. At the CBSC, only perform operations on expansion hardware when it is in the OOS_MANUAL state.
