Appendix E: Interference Sweep Procedure
Before You Start
The instructions in this document assume the Field Engineer is at the Base Station site and that the
BTS and RFS have not yet been installed.
Required Equipment
You will need the following equipment to perform the Interference Sweep:
?? HP4404B Spectrum Analyzer or equivalent. An equivalent analyzer must have the following:
- Screen Save abilities
- Max-hold function
- Peak search
- Ability to operate in the required frequency range
?? Omni or Directional Antenna for the given frequency range
The directional antenna should have a gain of > 9 dBi.
?? Cavity Filter
Pass band should cover the frequency range. It must have good out-of-band rejection so the
LNA is not jammed by high power AMP, PCS, or TV signals.
?? LNA Module
Gain > 21dB, NF < 7dB, for frequency range
?? Various SMA and N-Type adapters
?? Various RF cables to connect to Antenna and to test equipment
Initial Configuration
The set-up shown in Figure E1 and the information below are for the initial configuration. It gives
you a starting point for this procedure. During the later steps, this configuration will change.
