IntroductionJan 2002 G-1SCt4812ET BTS Optimization/ATP — CDMA LMFPurposeThis procedure is a guide to expanding your system with multiplecarriers while the system remains in service. This procedure also allowsyou to perform on site maintenance (replace defective boards andrecalibrate) while the remainder of the site stays in service.Motorola recommends that you perform this procedure during amaintenance 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 onetime. That is, LPAs 1, 2 ,3, 7, 8, 9 (feed antennas 1, 2, 3) can becalibrated while LPAs 6, 7, 8, 10, 11, 12 (feed antennas 4, 5, 6) remainin service and vice versa.Equipment Warm upCalibration of the communications test set (or equivalenttest equipment) must be performed at the site beforecalibrating the overall test set. Calibrate the test equipmentafter it has been allowed to warm-up and stabilize for aminimum of 60 minutes.IMPORTANT*If any piece of test equipment (i.e., test cable, RF adapter)has been replaced, re-calibration must be performed.Failure to do so could introduce measurement errors,causing incorrect measurements and degradation to systemperformance.CAUTIONG
Power Delta CalibrationSCt4812ET BTS Optimization/ATP — CDMA LMF Jan 2002G-2Power Delta CalibrationIntroductionThe In–service calibration procedure has several differences from anormal calibration procedure. One of these is the use of a spectrumanalyzer instead of a power meter to measure power. Power meters arebroadband measurement devices and cannot be used to measure powerduring In–service Calibration since other carriers are operating. Aspectrum analyzer can be used because it measures power at a givenfrequency. However, measuring power using a spectrum analyzer is lessaccurate than using a power meter. Therefore, you must compensate forthe difference (delta) between the power meter and the spectrumanalyzer.HP8921A Power DeltaCalibrationUse the HP8921A Spectrum Analyzer to measure power duringIn–Service Calibration for 800 MHz systems. After the offset value hasbeen calculated, add it to the TX cable loss value.Follow the procedure in Table G-1 to perform the HP8921A Power DeltaCalibration procedure.This procedure requires two HP8921As.NOTETable G-1: HP8921A Power Delta Calibration ProcedureStep Action* IMPORTANTPerform this procedure after test equipment has been allowed to warm–up and stabilize for a minimumof 60 minutes.1Connect a short RF cable between the HP8921A Duplex Out port and the HP437B power sensor (seeFigure G-1).2Set the HP8921A signal source as follows:–Measure mode to CDMA Generator–Frequency to the CDMA Calibration target frequency–CW RF Path to IQ–Output Port to Dupl–Data Source to Random–Amplitude to 0 dBm3Measure and record the power value reading on the HP437B Power Meter.4Record the Power Meter reading as result A ________________________.. . . continued on next pageG
