INTERFERENCE ANALYSIS (OPTION 25)
The interference analyzer option provides you with a spectrogram display,
RSSI, signal strength meter, signal ID, and Signal Mapping capabilities.
Site Master’s integrated spectrum analyzer can detect signals as low
as -152 dBm.
SPECTROGRAM DISPLAY
This option provides you with a three-dimensional display of frequency,
power, and time of the spectrum activity to identify intermittent interference
and track signal levels over time. The dual display screen allows for easy
viewing of both the spectrum and 3D display. The Site Master allows you to
save a history of data up to 72 hours.
SIGNAL ID
Site Master’s signal ID feature in the interference analyzer can help you
quickly identify the type of the interfering signal. You can configure this
measurement to identify all signals in the selected band or to simply monitor
one single interfering frequency. The Site Master then displays results that
include center frequency, signal bandwidth, and signal type (FM, GSM/
GPRS/EDGE, W-CDMA/HSDPA, CDMA/EV-DO, Wi-Fi).
CARRIER-TO-INTERFERENCE MEASUREMENT
Site Master’s carrier-to-interference measurement capability makes it simple
for you to determine if the level of interference will affect users in the
intended service area.
AM/FM/SSB DEMODULATION
A built-in demodulator for AM, narrowband FM, wideband FM and single
sideband allows you to easily identify the interfering signal.

Carrier-to-Interference (C/I)
As the wireless industry continues to expand, more diverse uses for the radio spectrum emerge, and the number of signals that may
potentially cause interference is constantly increasing.
Compounding the problem are the many sources that can generate interference, including intentional radiators, unintentional
radiators, and self interference. Interference causes Carrier-to-Interference degradation robbing the network of capacity.
The goal of these measurements is to resolve interference issues as quickly as possible.
Spectrogram Display
SIGNAL STRENGTH METER
The Site Master’s signal strength meter can locate an interfering signal by
using a directional antenna and measuring the signal strength. It displays
power in Watts or dBm, in the graphical analog meter display and by an
audible beep proportional to its strength.
