Close theTx Band Response Calibration window.Tx LO leakage (WCDMA)ContextThe purpose of Tx LO leakage tuning is to minimize the carrier leakage of the IQ-modulator which is causedby the DC offset voltages in the Tx IQ-signal lines and in the actual IQ modulator.The tuning improves WCDMA Tx AGC dynamics at low power levels. A self-calibration routine selects the bestcombination for internal control words in order to produce minimum LO leakage.Steps1. From the Operating mode drop-down menu, set mode to Local.2. Choose Tuning→WCDMA→ Tx LO Leakage .3. Click Tune.4. To end the tuning, click Close.Antenna troubleshootingContextThe antennas have contacts with the engine PWB via three pogo pins.The mechanical construction and antenna are described below.RM-132; RM-133Nokia Customer Care RF Troubleshooting and Manual Tuning GuidePage 7 –54 COMPANY CONFIDENTIAL Issue 1Copyright © 2006 Nokia.
