Setting the Pilot Dominance Limit

---

Pilot Dominance is only relevant to Over the Air measurements. It does not apply to Transmitter measurements.
Pilot Dominance is the difference between the useful energy of the strongest pilot channel and the combined energy of the lower energy active pilot channels (expressed in dB). Ideally, this value should be very large (> 16 dB).
The E7495A/B test set includes up to nine lower energy active pilots in the pilot dominance calculation. In live testing of 1xEV-DO networks, however, it is unlikely that you will have as many as nine interfering pilots.
If the measured Pilot Dominance meets the limit you have set, the numeric result displayed in the OTA PN Scanner section of the screen is displayed in green. If the measured Pilot Dominance fails to meet the limit you have set, the result is displayed in red font, and all metrics displayed in the metrics portion of the screen will be displayed in gray. This is to indicate to you that the metrics you are seeing are unreliable because the Pilot Dominance limit has not been met.

NOTE:

It is important to remember that the pilot dominance is always measured against the strongest signal. If you have specified your channel of interest manually, this channel might not necessarily be the strongest.
