PAMS Technical Documentation NSM–3/3D Tuning Instructions Tuning Instructions General All tuning operations are carried out using the service software. The service software turns the phone into the locals mode, in which the phone can be outwardly controlled via the MBUS interface. Tuning is based on the software communicating with the D/A and A/D converters of the phone. In some instances the phone processor will also calculate the required correction parameter.

PAMS Technical Documentation NSM–3/3D Tuning Instructions NOTE: Changes in Sales Packs In FPS–4S sales pack ACL–3E will be replaced by AXD–1 power cable.This cable makes it possible to power the FPS–4 prommer with ACH–6 type charger. Same charger has been used to power TDF–4 Flash Security Box and it must be purchased separately. AXD–1 power cable will be added to FLA–7 sales pack. This makes it possible to power FLA–7 from TDF–4 power output or separate ACH–6 type charger.

PAMS Technical Documentation NSM–3/3D Tuning Instructions Tuning Steps NOTE: All RF Tunings are made in Test Jig MJS–9. 1. RX Filter Calibration BB–filter tuning is fully internal operation. External signal generators etc. are not needed, only command for phone to execute filter calibration procedure. NOTE: RX Filter Calibration is needed when N505 has been changed. 2. RX Calibration (AGC + AFC) Procedure Follow the steps described in chapter ”Service Software Instructions” section ”RX calibration...
NSM–3/3D Tuning Instructions PAMS Technical Documentation 2. Measurement with high input level is executed 3. User is requested to put signal generator to low input level (read from .INI file). 4. Measurement with low input level is executed 5. The RX Calibration dialog will be updated when previous steps are done. Software reports the following: AFC init value AFC slope PSW slope Gain step values Page 14 Nokia Mobile Phones Ltd.
NSM–3/3D Tuning Instructions PAMS Technical Documentation Limits for the reported values After the calibration reported values should be approximately following: Parameter Low limit High limit AFC init value –200 200 AFC slope 135 345 PSW slope For information Gain step values EGSM (nominal) PCN (nominal) 0 37 28 1 47 38 2 57 48 3 62 53 4 72 63 5 82 73 6 92 83 7 102 93 8 112 103 Troubleshooting If the calibration does not succeed the software normally reports ”Unab
NSM–3/3D Tuning Instructions PAMS Technical Documentation 3. AM suppression tuning This operation is recommended when RX components have been changed (between N505/Hagar and Z670/antenna switch). AM suppression calibration is for tuning four Hagar parameters to get as small RSSI value as possible. For AM–suppression calibration external signal generator with AM–modulation is needed. Select Am Suppression... from Tuning menu. Signal generator setup: AM–modulation, fmod = 1 kHz, mod.
PAMS Technical Documentation NSM–3/3D Tuning Instructions Test limits for AM–calibr. results: –86 dBm (EGSM) –95 dBm (PCN) Press Save button to save the values. NOTE: AM suppression calibration is needed for the PCN band as well. To change the band go to Product Menu and select Band, PCN. Issue 4 02/2002 Nokia Mobile Phones Ltd.
NSM–3/3D Tuning Instructions PAMS Technical Documentation 4. Alignment of Transmitter Power Levels Equipment: Pulsed power meter or spectrum analyzer and 10 dB attenuator. Voltage source set to 3.6 V. The following settings for the spectrum analyzer are recommended when aligning the power levels: zero span, resolution and video bandwidths 1 MHz, input attenuation 40 dB, sweep time 1 ms, video triggering.
NSM–3/3D Tuning Instructions PAMS Technical Documentation GSM1800 TX Power Tuning dialog: 5. I/Q Modulator Alignments I/Q modulator alignments has to performed in both bands. See chapter ”Service Software Instructions” and section ”TX I/Q... command” for further information. –67.71 kHz D.C. offset tunings: Set this value to minimum Issue 4 02/2002 CHF +67.71 kHz > 30 dB Nokia Mobile Phones Ltd.
NSM–3/3D Tuning Instructions PAMS Technical Documentation Procedure: Connect the spectrum analyzer to the phone antenna connector. The recommended spectrum analyzer settings are: span 200 kHz, resolution BW 10 kHz, video BW 1 kHz, sweep 500 ms, input attenuation 30 dB. – From RF controls menu make sure that TX data type is 1. – Go to TX I/Q tuning menu. The alignment channel for EGSM is 60 (902 MHz) and for PCN is 700 (1747.8 MHz).
PAMS Technical Documentation NSM–3/3D Tuning Instructions 6. Energy Management Calibration See section ”Tuning – Energy Management Calibration... command” for further information. NOTE: This Calibration must be done when N100, N101 or a discrete component affecting these two is changed. Before battery a/d tuning is started a voltage setting request is shown to user (Set supply voltage to 10,5 V). Service Battery is in this case JBU–6.
