Interference Analysis – Critical to Wireless
Networks
The LMR Master interference analyzer
option provides technicians and field
engineers the ability to identify and
locate interfering signals that affect
quality of service. The LMR Master,
with built-in preamplifier, can measure
signals down to –135 dBm.
Interference Analyzer (Option 0025)
Spectrogram
The LMR Master Spectrogram is a three dimensional display of
frequency, power and time of the spectrum activity to identify
intermittent interference and track signal levels over time.
The LMR Master can store up to three days worth of measurements.
RSSI
RSSI measurement is useful to observe the signal strength of a single
frequency over time. The data can be collected for up to seven days.
Locating an Interfering Signal
Connect a directional antenna to the LMR Master and locate the
interfering source by measuring the strength of the interfering signal.
Signal strength is indicated as an audible beep.
