INTERFERENCE ANALYSIS (OPTION 25)
The interference analyzer option provides you with a spectrogram display,
RSSI, signal strength meter, and signal ID. 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 Site Master allows you
to save a history up to 72 hours.
RECEIVED SINGLE STRENGTH INDICATOR (RSSI)
You can use the Site Master’s RSSI measurement to observe the
signal strength of a single frequency over time, and collect data for up to
72 hours.
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, dBm, in the graphical analog meter display, and by an
audible beep proportional to its strength.
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).
AM/FM/SSB DEMODULATION
A bulit-in demodulator for AM, narrowband FM, wideband FM and single
sideband allows you to easily identify the interfering signal.

are on, or off
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, un-intentional
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.
