If antenna misalignment is not required as per «8» above, connect the test equipment as shown in Figure 19 – Antenna misalignment with E-RIT tool (with Enhanced RIT tool) while inserting the appropriate IGAU type value as recorded in «5» and «6» above. If antenna misalignment is required, proceed directly to «19». 10. Ensure that the base station is transmitting a signal in the desired sector. 11.
27. If vertical, fine align the X-Pol RT antenna to maximum field strength using the spectrum analyzer and record the level. If this recorded level is already 15 dB below the calculated RSL, natural misalignment due to the elevation relationship between the BS and TS has occurred and no further misalignment is necessary. Proceed to «29». 28.
