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. The procedure can only be performed on one side of the BTS at one time.
Introduction – continued IMPORTANT * IS–95A/B communication test sets such as the HP8921A/600 and Advantest R3561L can not calibrate 1X carrier functions. Calibration and test set–up for the HP 8921A/600 and Advantest R3561L test sets is included only for situations where it is necessary to use them for calibration of IS–95A/B mode operation.
Power Delta Calibration 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.
