Built-in spectrum analyzer
Interference is a major source of cell site
problems. Interference can be internal or
external, and uplink or downlink. Downlink
interference reduces coverage, while uplink
interference causes access failure. Inter-
ference has a direct impact on the quality of
service of wireless communication services.
FieldFox has an optional built-in spectrum
analyzer that covers frequency ranges from
5 kHz to 6 GHz. It provides a fast spectrum
scan to detect interference and RF burst
capture to measure intermittent signals. It
displays four traces at the same time, and
you can choose different detector modes.
Field strength measurements
Field strength characterization is a common
test performed by operators in the field.
To make accurate measurements, the gain
and loss of the antenna and cables need to
be accounted for. With FieldFox, antenna
factors and cable loss data can be loaded
using either the front panel or the Data Link
software.
Interference analyzer
FieldFox interference analyzer is designed
for identifying interference signals quickly
in the field. It has the best dynamic range
on the market (96 dB) with very fast sweep
times under narrow resolution bandwidths
(RBWs).
FieldFox provides a spectrogram and water-
fall display to detect intermittent interference
signals or monitor signals of interest for
longer periods of time. Signal traces can be
recorded into internal memory or external
flash memory devices, the saved traces can
be played back for offline processing.
FieldFox also allows you to listen to
demodulated AM/FM signals to identify
signal types.
