Tuning Instructions
General
All tuning operations of the NSC-1/3 and NSW-1/3 phones are carried out using the ser-
vice 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 also will calculate the required correction
parameter.
The tuning values of the phone reside on the EEPROM. The contents of the EEPROM can
be read by the service software and saved as a file. This is advisable when there is need
to retain that information (e.g., in view of replacement of the circuit). The program also
enables writing the default parameters on the EEPROM, in which case all tuning steps
should be carried out.
Note: NSC-1 and -3 do not have upper band components. NSC-1 and -3 are 800 MHz transceivers.
During tuning, proceed as follows:
• Take care not to damage sensitive measuring instruments with exces-
sive RF power.
• Carry out all tuning steps quickly to avoid excessive heating of RF units.
• Perform all tuning steps in the order presented.
• Never try to mask a fault by tuning it out!
Required Equipment
1 PC/AT computer with service software. (See separate section for instructions on
installation and use.)
2 Service accessories. (See equipment setup pictures.)
3 Multimeter or DVM.
4 GSM radio telephone test station or separate measuring equipment as follows:
• RF generator
• pulse power meter
• spectrum analyzer
• attenuator and branching unit

Equipment Setup
Caution: Makesure thatyouhaveswitched off the PCandtheprinter before making con-
nections.
Caution: Do notconnectthe protection key (PKD-1)totheserialport. Theresultmaybe
damagetothePKD-1.
Attach the protection key PKD-1 to the PC’s parallel port 1 (25-pin female D-connector).
When connecting the PKD-1 to the parallel port, be sure that you insert the PC end of
the PKD-1 to the PC (male side). If you use a printer on parallel port 1, place the PKD-1
between the PC and your printer cable.
Next, connect the M2BUS service cable (DAU-9P) to the PC’s serial port (RS-232). Attach
one end of the service cable to the PC serial port and the other end to the service box
(JBA-4).
The service box should always be used when servicing the phone with the covers in place.
When the phone covers are removed, the jigs should be used.
For audio measurements, connect the audio cable (ADS-1) as follows:
• EAR line to AF INPUT of test equipment
• MIC line to MOD GEN OUTPUT of test equipment

Warranty Transfer
Warranty Transfer
The Warranty Cable (SCH-6) is used to connect two phones to enable the transfer of
warranty data (user settings and serial numbers) from one phone to another phone.
No warranty transfer is permitted between 6160 P1 and P3.
The warranty transfer procedure is as follows:
Point Of Sale
Phone No. 1 is broken.
1 To avoid confusion, label the phones No. 1 and No. 2.
2 Plug the Warranty Cable (SCH-6) into both phones (see diagram above).
3 Turn on phone No. 2. Select Profiles from the menu and select “Silent”.
4 Start the warranty data transfer by selecting code #92772689# in phone No. 2.
5 Select the “Transfer user data?” option and press OK. The next prompt is: “Con-
firm transfer?” Press OK again.
6 Wait until the transfer is completed.
7 Turn off phone No. 2, then turn it on again. Check the Welcome note and profile

Tuning Steps
1. AFC Tuning (Analog)
This tuning adjusts reference oscillators frequency so that the network’s frequency crite-
ria will be met.
This adjustment loads the Analog center frequency DAC value into the EEPROM. A spec-
trum analyzer must be used to accomplish this task.
Note: Do not leave tuning on. Analog transmitting takes maximum current. Tuning can damage the
phone or service battery. The service battery will be heated.
The spectrum analyzer settings are shown in the AFC tuning window:
• Set the power supply voltage at 8.4V to service battery (or 3.6V to jig).
• Connect the spectrum analyzer to antenna connector.
• Verify that the spectrum analyzer frequency is correct.
• Tune the center frequency (CFR) to 832.500 MHz +/- 200 kHz.
• Press the OK button when the center frequency is correct.
2. VCTCXO Tuning
This tuning is used to verify that the radio unit has the correct adjustment to meet a net-

NSC/W-1/3
Tuning Instructions PAMS Technical Documentation
Page 16 Nokia Mobile Phones Ltd. Issue 4 03/01
work’s criteria for frequency stability.
This adjustment loads the VCTCXO DAC value into the EEPROM. The RF generator must
be used in this process.
The spectrum analyzer settings are shown in the AFC tuning window:
• Set the power supply voltage at 8.4V to service battery (or 3.6V to jig).
• Connect the antenna connector to RF generator.
• Once all the RF generator frequency information is correct, press the
Meas button.
• Set the correct RF level to signal generator (Note: Attenuation).
• Press the OK button when the frequency and RF level are correct.
3. Modulator Output - Low Band/High Band (NSW-1/3 only)
This tuning is used to adjust the radio unit’s intermediate frequency level so that the RF
small signal gain has its maximum dynamic range in use with some drift margin.
Here are the steps to perform:
• Select Tuning>Modulator output>Low Band/High Band.
• Set the power supply voltage at 8.4V to service battery (or 3.6V go jig).
• Connect the pulse power meter or spectrum analyzer to antenna con-
nector.
• Check that the spectrum analyzer frequency is correct (RF information
shows correct frequency).
• Tune the modulator output power to 22dBm.
• Press the OK button when the tuning level is correct.
4. TX I/Q Modulator Amplitude Balance and Phase Shift Tuning
This tuning is used to adjust the I/Q-modulator’s DC offset and phase error so that the
system’s requirements for modulation accuracy are met.
Follow the steps as described here:
• Select Tuning>TX I/Q
• Connect the spectrum analyzer to the phone antenna connector (use
attenuator, if needed).

• Check that the TX power level is at level 10, the channel is at 60, and
the TX data type is set to 1.
• Adjust the spectrum analyzer center frequency to 830.700 MHz. Check
all other settings by pressing <Settings>.
• Select the TX I d.c. offset option from the “Tuning” drop-down menu.
• Adjust the level of center frequency (CHF signal) to minimum by varying
D/A converter value with the <and >buttons.
• Verify that the amplitude difference between CHF -9.1125 kHz and CHF
is >30 dB.
• Select TX Q d.c. offset from the “Tuning” drop-down menu.
• Adjust the level of CHF signal to minimum by varying the D/A converter
value with the <and >buttons.
•UsetheAmplitude Difference option.
• Adjust the level of signal CFR -9.1125 kHz to minimum by varying D/A
converter value with the < and > buttons.
• Verify that the amplitude difference between CHF +67.7 kHz and
CHF -67 kHz is >35 dB.
• Select the Phase Difference option from the “Tuning” drop-down menu.
• Adjust the level of signal CHF +67.7 kHz to minimum by varying D/A

• After verying that all values are correct, press the Save button.
5. TX Power - Low Band/High Band
Note: Use a Service Battery connected to 1.5A 8.4V power supply or use the phone’s own battery.
This tuning is used to adjust the radio unit’s output power level values according to sys-
tem specification.
This adjustment loads the power levels of the phone transmitter into the EEPROM. A
pulse power meter or spectrum analyzer must be used.
The <Settings> shows the spectrum analyzer settings.
The following steps are used for power levels programming:
• Select Tuning>TX Power>Low Band/High Band
• Read old tuning values from the phone’s EEPROM. Repeat this test to
tune all power channels (A, B, C, and D).
• Set the power supply voltage to 8.4V to service battery (or 3.6V to jig).
• Connect the pulse power meter or spectrum analyzer to antenna con-
nector.
• Verify that the spectrum analyzer frequency is correct using the follow-
ing settings:
• Set span 0 Hz
• Set Ref LVL 30 dB
• Set Ref LVL offset = cable loss
• Set RBW and VBW 300 kHz
• Set TRIG: SWEEP CONT, VIDEO -10dBm
• Set marker at middle of slot
• Adjust the power level by clicking the +and -buttons; change the levels
using the up arrow and down arrow keys.
• Tune power levels 2, 7, and 9.
•UsetheCalculate button to calculate all other levels.
