Interference finder
The Interface Finder is an automatic triangulation algorithm that uses GNSS coordi-
nates to locate possible interference sources based on the three measurements. The
interference finder calculates possible interference locations using its inscribed circle or
circumscribed circle based on measured intersection points. You can plot up to seven
measurement points and select three that are more representative for triangulation.
The SPA06MA-O automatically logs measurement positions so as to prevent their loss
while changing measurement modes.You can switch the main screen from spectrum
view to map view and vice versa using the icon on the spectrum view screen. Before
starting the Interference Finder, you need to set spectrum measurements, as described
in
"Configuring spectrum measurements" on page
To make full use of the functions available in map mode, you will need a GNSS receiver
and antenna.
Antenna connection
Before starting the measurement, you need to connect the Omni or Log periodic
antenna to your instrument. In the Interference Finder and the Radar Chart modes, you
can perform interference hunting using the optional AntennaAdvisor Handle after
attaching a broadband directional antenna to it. The handle is a device that has a built-
in GNSS antenna and LNA. The following are examples of the antenna connection.
To connect an antenna
1
Mount a broadband antenna to your AntennaAdvisor Handle.
2
Connect the RF Type-N Jack of the handle to the RF In port of the instrument.
