NSW-4 Tuning Instructions PAMS Technical Documentation Tuning Instructions General All tuning operations of the NSW-4 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 NSW-4 Tuning Instructions Tuning Steps Note About Supply voltage. The Service battery (Flash adapter) FLA–12 used for NSW-4 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.
NSW-4 Tuning Instructions PAMS Technical Documentation 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.
NSW-4 Tuning Instructions PAMS Technical Documentation – –Settings for pulse power meter: – Do calibration if needed. – Set correct frequency – Set Ref LVL offset ––> Attenuation to Antenna Pad – Set correct duty cycle, 33,3 % in digital mode and 100 % at analog mode. – –Select Tuning –> Using WinTesla Select Tuning –> TX power –> LowBand/HighBand –>EEPROM values – –All four tuning channels have to be tuned. Repeat tuning for A, B, C and D tuning channel.
