NEW MCU SOFTWARE VERSION 4.43

New MCU software version 4.43 has been released for NSE-8 products.

Changes made from version 4.41 to version 4.43:

- TxP offset changed for Philips Power Amplifier

- Side channel compensation has been activated

- Viag home zone correction done

Note 1: A new flash device from ATMEL (code 4340789) is also implemented in system module GD7_xx, and before attempting to re-flash ATMEL devices, the support device list file (diskette code : 0774228) in the FPS-4 prommer box need to be updated to version 1.11, refer to the FPS-4 Device list update section.

Note 2: RF tuning has been changed with version 4.43, due to the fact that side channel compensation has been activated. This requires the use of Service Software version 241.04.00 or later to be able to tune the RF parameters, refer to the tuning instruction section.

Note 3: Transceivers using Philips Power Amplifier have own transceiver codes (e.g. for Language package Euro A the code for transceiver with Philips Power Amplifier is 0505103).

FPS-4 Device list update:

DEV_A111.EXE (self-extracting file, contains flash device list)

1.     Copy 'DEV_A111.EXE' to 'DEVICE' sub-directory under your FPS4-directory (e.g. C:\FPS4\DEVICE). If 'device' sub-directory is missing, install latest FPS4 release.

2.     Execute 'DEV_A111.EXE'

3.     Enter the FPS4-directory and run 'SETUP'

Tuning Instructions

Due to the introduction of the Philips PA, side channel tuning became an issue. Therefore we had to change the software for both the Hitachi and the Philips version to include side channel tuning.

Hitachi PA GSM tuning.

1.     From WinTesla select the band GSM and tune TxPower.

2.     This start is the same for both bands, select the EEPROM Values.

3.     The next picture is different for GSM and PCN; The base offset must be set to 0.06 for Hitachi GSM.

GSM Hitachi, TX power tuning.

4.     Tune coefficients at power level 5, 15 and 19 (Don't check out the Base level calculation box)

5.     Click "Calculate" or Press Ctrl+A.

6.     Set BASE coefficient 0.060 under power level 19.

7.     Check that BASE level is less than -30.0 dBm. If not step down the coefficient, but don't exceed a offset from power level 19 of 0.080

When saving the results the side channel tuning pops up.

8.     Select the EEPROM Values (see picture on next page).

GSM Hitachi, TX power side channel tuning.

9.     Set channels thresholds: Low channel = 60 and High channel = 60.

10. Select channel 1 power level 19 and set the compensation to the nominal value 0.004 (as close as possible)

11. Select channel 124 power level 19 and set the compensation to the nominal value 0.008 (as close as possible)

12. Save and exit

Hitachi PA PCN tuning.

PCN Hitachi, TX power tuning.

1.     The base offset must be set to 0.06 for Hitachi PCN.

2.     Tune coefficients at power level  0, 11 and 15. (Don't check out the Base level calculation box)

3.     Click "Calculate" or Press Ctrl+A.

4.     Set BASE coefficient 0.060 under power level 15.

5.     Check that BASE level is less than -30.0 dBm. If not step down the coefficient, but do not exceed an offset from power level 19 of 0.080.

When saving the result the side channel tuning pops up.

6.     Select the EEPROM Values (see picture on naext page)

PCN Hitachi, TX power side channel tuning.

7.     Set channels thresholds: Low channel = 612 and High channel = 850.

8.     Select channel 512 power level 15 and set the compensation to the nominal value 0.005 (or as close as possible)

9.     Select channel 885 power level 15 and set the compensation to the nominal value 0.007 (or as close as possible)

10. Save and exit.

Philips PA GSM tuning.

1.     From WinTesla select the band GSM and tune TxPower.

2.     This start is the same for both bands, select the EEPROM Values.

1.     The next picture is different for GSM and PCN, The base offset must be set to give less than –30dBm at base level for Philips GSM.

GSM Philips, TX power tuning.

2.     Tune coefficients at power level 5, 15 and 19 (Don't check out the Base level calculation box)

3.     Click "Calculate" or Press Ctrl+A.

4.     Set BASE coefficient 0.055 under power level 19.

5.     Check that BASE level is less than -30.0 dBm. If not step down the coefficient, but don't exceed -35.0 dBm.

When saving the result the side channel tuning pops up.

6.     Select the EEPROM Values (see picture on next page).

GSM Philips, TX power side channel tuning.

7.     Set channels thresholds: Low channel = 30 and High channel = 80.

8.     Select channel 124 power level 19 and set the compensation to the nominal value 0.003 (or as close as possible)

Philips PA PCN tuning

PCN Philips, TX power tuning.

1.     The base offset must be set to give less than –30dBm at base level for Philips PCN.

2.     Tune coefficients at power level  0, 11 and 15 (Don't check out the Base level calculation box)

3.     Click "Calculate" or Press Ctrl+A.

4.     Set BASE coefficient 0.035 under power level 15.

5.     Check that BASE level is less than -30.0 dBm. If not step down the coefficient, but don't exceed -35.0 dBm.

When saving the result the side channel tuning pops up.

6.     Select the EEPROM Values (see picture below).

PCN Philips, TX power side channel tuning.

7.     Set channels thresholds: Low channel = 612 and High channel = 750.
