Tuning Instructions
General
All tuning operations of the NSW–6 are carried out using the service soft-
ware. 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.
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.
During tuning, proceed as follows:
– Take care not to damage sensitive measuring instruments with exces-
sive RF power.
– Carry out all tuning steps in the shortest possible time to avoid exces-
sive heating of RF units.
– Perform all tuning steps in the order presented.
– Never try to mask a fault by tuning it out!

Required Equipment
– PC/AT computer with service software; see separate section for
instructions on installation and use.
– Service accessories; see equipment setup pictures.
– Multimeter or DVM.
– Measuring equipment as follows:
– RF generator
– pulse power meter
– spectrum analyzer
– attenuator and branching unit
Equipment Setup
Caution: Make sure that you have switched off the PC and the printer
before making connections !
Caution: Do not connect the PKD–1 key to the serial port. You may
damage your PKD–1 !
Attach the protection key PKD–1 to parallel port one (25–pin female
D–connector) of the PC. 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 one, place the PKD–1 between the PC
and your printer cable.
Next connect the M2BUS service cable, DAU–9S, to the serial port
(RS–232) of the computer. Attach one end of the service cable to the PC
serial port and the other end to the service box, JBU–8 or Flash Adapter
FLA-9.
When the phone covers are removed the jig JBS-25 must be used.
For audio measurements the audio box JBA-6 is used.
Warning: Do not use JBU–8 for tuning!

Tuning Steps
Note About Supply voltage.
The Service battery (Flash adapter) FLA–9 used for NSW–6 differs from
the standard DCT3–Service battery. The max. supply voltage is 16 V.
1. AFC Tuning
This tuning adjusts the frequency of the reference oscillator so that the
frequency criteria of the network will be met.
This adjustment loads the analog center frequency offset DAC value into
the EEPROM. When doing this, a spectrum analyzer must be used.
Note:
Do not leave a tuning session on. The analog transmitting takes maximum
current. A prolonged tuning session may 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. See instructions above.
– – Connect the spectrum analyzer to the antenna adapter or to the
diagnostic jig.
– – Check that the spectrum analyzer center frequency is correct.
– – Tune the center frequency 832.500 MHz +/– 200 Hz.
– – Once the center frequency is correct, press OK button.
2. VCTCXO Tuning
This tuning is to check that the radio unit has correct adjustment to meet
the network criteria for frequency stability.
This adjustment loads the VCTCXO offset DAC value into the EEPROM.
RF signal generator must be used in tuning.
– –Set the power supply voltage. See instructions above.
– –Connect the RF signal generator to the antenna adapter or to the
diagnostic jig JBS–25.
– –Once the RF signal generator frequency is correct, press Meas but-
ton.
– –Set the correct RF level to the signal generator.
– –Remember to note the attenuation at RF signal level !
– –Once the frequency and RF level are correct, press OK button.

3. I/Q Modulator Amplitude Balance and Phase Shift Tuning
This tuning is to adjust the DC–offset and phase offset of the I and Q–
modulators so that the system requirements for modulation accuracy will
be met.
– –Select Tuning ––> TX I / Q
– –Connect the spectrum analyzer to the antenna adapter or diagnostic
jig.
– –Use the following settings for spectrum analyzer in tuning:
– Set spectrum analyzer center frequency to 830.700 MHz.
– Set span 80 kHz
– Set Ref LVL 20 dB
– Set RBW and VBW 1 kHz
– Set sweep time 0.3 s
– –Use ”TX I DC Offset” and ”TX I DC Offset” option to adjust CFR – 7.1
kHz to minimum.
– The amplitude difference between CFR and CFR – 7.1 kHz must be >
40 dB.
– –Use ”Phase Offset ” option to adjust CFR – 14.2 kHz to minimum
– The amplitude difference between CFR and CFR – 7.1 kHz must be >
40 dB.
– –Once the TX I, TX Q and phase shift are aligned, press SAVE button.
4. Tuning of Transmitter Power Levels
– This tuning is to adjust the output power level values of the radio unit
according to the system specification.
– This adjustment loads the power levels of the phone transmitter into
the EEPROM. When doing this, a pulse power meter or spectrum
analyzer must be used.
– Tuning targets are listed next page.
– –Set power supply voltage. See Note above.
– –Connect the pulse power meter or spectrum analyzer. Use attenua-
tor, if needed.
– – Settings for spectrum analyzer in power level tuning:
– Set span 0 Hz
– Set Ref LVL 30 dB
– Set Ref LVL offset and ––> Attenuation to Antenna Pad
– Set RBW and VBW 300 kHz
– Set sweep time 50 ms
– Set TRIG: SWEEP CONT, VIDEO –10 dBm
– Set marker at middle of slot.
– Check that spectrum analyzer frequency is correct
