Clicking the Channel Info tab provides the following fields as shown in Figure: Signal ID File Tab. PoA on the Channel Info tab page will use the time of the current trace if the user has scrolled back. If the user has not scrolled back, it will look for the maximum power at the set frequency over the most recent 30 traces in order to get the best results. The PoA under the Channel Info tab page in Vision Monitor assumes omni-directional antennas and does not do a search to optimize sectors. The Channel Info PoA has no setup and provides a search result estimate only. For a more sophisticated method for obtaining optimum search results, refer to PoA Settings and Control.
