This is most easiest done by measuring the UHF VCO (G550) frequency because the absolute value of the deviation is biggest there. In the GSM mid channel the UHF–VCO frequency should be 2040.0 MHz.

Page 12: Alignment Of Transmitter Power Levels
PAMS NSM–1 Tuning Instructions Technical Documentation 2. 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. - Page 13 PAMS NSM–1 Tuning Instructions Technical Documentation It is recommended that all the power levels are separately aligned al- though there is a possibility to align only three and calculate the rest. This is due to the fact that the calculation is not accurate enough, especially for PCN lowest power levels where the targets are NSM–1 specific.

Page 14: I/Q Modulator Alignments
PAMS NSM–1 Tuning Instructions Technical Documentation 3. I/Q Modulator Alignments I/Q modulator alignments are performed in PCN band. If GSM band has been selected and I/Q alignment is started, the service software asks to change to PCN band. If the user wants to continue in GSM, the adjusted values can only be saved to PC memory, not to phone’s EEPROM. - Page 15 PAMS NSM–1 Tuning Instructions Technical Documentation – Check the levels of CHF and CHF + 67.71 kHz. Both the levels should be at least 30 dB down to the wanted sideband CHF - 67.71 kHz. If both or either of the specifications is not met adjust the the re- quired values (I and Q DC offsets for CHF and amplitude and phase for CHF + 67.71kHz) to meet the specifications.
