Vision™ MX280001A Spectrum Monitoring Application Software : Vision Locate (Option 401) : Location Finder (Option 401) : PoA Settings and Control
 
PoA Settings and Control
The Vision Locator's Power of Arrival (PoA) settings and control panel displays the menu selections shown in Figure: PoA Settings and Control. Power of Arrival and Control panel provides the means of loading the trace data and lets the user scroll through the traces on that screen. Note that the PoA settings and Control panel setup does not automatically synchronize with the time stamp of the current trace in Vision Monitor; therefore, the sophistication of PoA Settings and Control panel measurements provide the optimum search results.
PoA Settings and Control
The PoA Settings and Control selection tabs are described in Table: PoA Settings and Control Buttons.

Description
Synchronize Traces in Time
Toggles time synchronization between the three monitors used in the location algorithm. Each trace graph has a horizontal scroll bar that allows the user to scroll through the trace history and look for a particular trace that exhibits the interference most strongly.
Restrict Search Area
Toggle Clipping mode: Only looks for sources in the overlap region of sectors.
Peak Tracking
Tracks signal peaks.
Optimize Sectors
Find Sectors with maximum Power at Source Frequency. Click to locate base station(s) that transmit the most power at the source frequency.
Show Heat Map
Isolates the interferer signal by displaying a heat sense map over the suspected region.
3-Probes-PoA
Triangulate the interferer position when the signal of interest can be seen on three near-by monitors. This is normal mode.
3 Probes-AM
Triangulate the interferer position in AM-mode when the signal of interest can be seen on three near-by monitors.
1-Probes-PoA
View signals at a single monitor, from the Probe pull-down list above the top trace display. 1 Probe detection is only useful if the interferer can be seen in the sweep data on two more channels on the same monitor. Save PoA mode to 1-probe (Angle of Arrival).
Search Rectangle Size
Use the scroll bar to set the line lengths on the map.
