RM-378; RM-379 RF troubleshooting General RF troubleshooting Introduction to RF troubleshooting Troubleshooting process RF troubleshooting is performed in this order: 1 Autotuning 2 General power checking 3 Selftests 4 RX and TX troubleshootings Most RF semiconductors are static discharge sensitive ESD protection must be applied during repair (ground straps and ESD soldering irons).
RM-378; RM-379 RF troubleshooting RF key components Figure 13 RF key components Auto tuning for RF This phone can be tuned automatically. Autotune is designed to align the phone's RF part easier and faster. It performs calibrations, tunings and measurements of RX and TX. The results are displayed and logged in a result file, if initiated.
RM-378; RM-379 RF troubleshooting Phoenix preparations Install the phone specific data package, for example RM-378/379_dp_1.78_sw_sh3.26.exe. This defines phone specific settings.. Auto tuning procedure 1 Make sure the phone (in the jig) is connected to the equipment. Else, some menus will not be shown in Phoenix. 2 To go to autotune, select Tuning (Alt-U) > Auto-Tune (Alt-A) from the menu. 3 Start autotuning, clicking the Tune button. General voltage checking Steps 1.
RM-378; RM-379 RF troubleshooting Selftest troubleshooting RF selftests Prerequisites Do a hardware initialization before you start the selftests: Testing→GSM→RF Controls→ RX and then press Stop. Context Note: The RF connector should be terminated to 50 Ohms or connected to the antenna. Check this carefully before performing the self tests. Note: The phone should be in local mode when performing Self tests Page 4 –8 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
RM-378; RM-379 RF troubleshooting Steps 1. Check the tests shown in the figure below: Testing→ Self Tests , and press the Start button. 2. A test is either Passed or Fatal.

RM-378; RM-379 RF troubleshooting The main RX troubleshooting measurement is RSSI reading. This test measures the signal strength of the received signal. For GSM RSSI measurements, see GSM RX chain activation for manual measurements/GSM RSSI measurement.
RM-378; RM-379 RF troubleshooting Transmitter troubleshooting General instructions for transmitter (TX) troubleshooting Please note the following before performing transmitter tests: • TX troubleshooting requires TX operation. • Do not transmit on frequencies that are in use! • The transmitter can be controlled in local mode for diagnostic purposes. • The most useful Phoenix tool for GSM transmitter testing is “RF Controls”.
RM-378; RM-379 RF troubleshooting 3. Check the basic TX parameters (i.e. power, phase error, modulation and switching spectrum), using a communication analyser (for example CMU200). Figure 20 Typical readings Page 4 –16 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
RM-378; RM-379 RF troubleshooting 4. Change power level (RF controls) and make sure the power reading follows accordingly. Next actions TX is failing and RX is OK: replace N1002 If you want to troubleshoot the other bands, change band with RF controls and set the communication analyzer accordingly.

RM-378; RM-379 System Module Introduction Phone description RAP is the main digital baseband ASIC in the phone. It contains functionality for GSM EDGE. N2200 (AVILMA) is mainly the audio ASIC in the phone and N2300 (BETTY) is basically the energy management controller for the phone.

RM-378; RM-379 System Module Board and module connections Energy management Battery and charging BL-4CT battery The phone is powered by a 3-pole BL-4CT 860 mAh battery. The three poles are named VBAT, BSI and GND where the BSI line is used to recognize the battery capacity. This is done by means of an internal battery pull down resistor.

RM-378; RM-379 System Module Figure 22 Battery pin order The battery temperature can be measured from the UI flex. Battery connector The battery connector is a blade connector. It has three blades; • BSI (Battery size indicator) • GND (Ground) • VBAT (Battery voltage) The BSI line is used to recognize the battery capacity by a battery internal pull down resistor. Figure 23 Battery connector Charging This phone is charged through a separate charger connector.

When the power key is pressed, the system boots up (if an adequate battery voltage is present).
RM-378; RM-379 System Module SIM interface The device has one SIM (Subscriber Identification Module) interface. It is only accessible if battery is removed. The SIM interface consists of an internal interface between RAP and EM ASIC AVILMA (N2200), and of an external interface between N2200 and SIM contacts. The SIM IF is shown in the following figure: Figure 24 SIM interface The EM ASIC AVILMA handles the detection of the SIM card. The detection method is based in the BSI line.
RM-378; RM-379 System Module µSD card interface The µSD card is connected to the engine by an external level shifter and ESD protection filter. Supplied voltages: • VMMC: 2.85 V (from level shifter) • VIO: 1.8 V (from AVILMA) The card removal is detected by a push detect switch. User interface Display module The interconnection between the LCD module and the engine is implemented with a 24-pin board-to-board connector. The LCD module does not require any tuning in service.
RM-378; RM-379 System Module Audio concept This phone has a conventional solution on earpiece and vibra. Both are handled by AVILMA N2200. Two integrated handsfree speakers are driven by an additional amplifier also handled by AVILMA. The microphone has a digital interface and its RF-filtered lines are directly connected to RAP D2800 for processing. Issue 1 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
RM-378; RM-379 System Module Figure 25 Audio block diagram AV connector The AV connector is used to connect headsets both in the handsfree phone function and for using the phone as a media player (see the audio concept heading). The six pins are used in accordance with the table below. A connected male connector is detected on pin 6 (PLUG_DET). Note: Only use an approved cable for connecting to the AV connector ( e.g. headset HS-47). Page 5 –14 COMPANY CONFIDENTIAL Copyright © 2008 Nokia.

RM-378; RM-379 System Module RF description Receiver (RX) An analogue signal is received by the phone's antenna. The signal is converted to a digital signal and is then transferred further to the baseband (eg. to the earpiece). The receiver functions are implemented in the RF ASIC. Signals with different frequencies take different paths, therefore being handled by different components. Transmitter (TX) The digital baseband signal (eg.
RM-378; RM-379 System Module Bluetooth Bluetooth provides a fully digital link for communication between a master unit (the phone) and one or more slave units (e.g. a wireless headset). Data and control interface for a low power RF module is provided by the module. Figure 26 Bluetooth interface The Bluetooth has a separate built in antenna and is powered by VBAT and the regulated voltage VIO. For audio applications the Bluetooth has a PCM data bus.

RM-378; RM-379 System Module Environmental condition Humidity and water resistance Ambient temperature Notes Relative humidity range is 5 to 95%. Condensed or dripping water may cause intermittent malfunctions. Protection against dripping water has to be implemented in (enclosure) mechanics. Continuous dampness will cause permanent damage to the module. Issue 1 COMPANY CONFIDENTIAL Copyright © 2008 Nokia. All rights reserved.
