4.3.5. TX-Power Scaling Factors (2)
1. Select the test band mode (setp !).
2. Enter the middle ARFCN of each band, click
[APPLY] tab (step W); ex. EGSM = 37.
8
Set tester in the same channel
3. Enter Scaling Factor (step E), PL 5 value is the
reference (step R), click [APPLY]
8
Read the TX output power value on the tester.
Compare with the actual specification (33 dB ± 3
dB).
8
The best highest Scaling factor is not more than
60,000.
8
You may check any PL. Use the corresponding
Scaling Factor of that PL.
4. Repeat until the best factor according to the ideal
output power value is viewed on the tester and
enter that value in the corresponding grid cell (PL
5).
5. Repeat steps 1 to 4 for other bands, Click [WRITE]
tab (step T) if the all bands are completed.
