What is Spectrum View

The RADWIN Manager Spectrum View utility is an RF survey tool designed to support the sec-
tor installation prior to full sector service activation. The tool provides comprehensive and
clear spectral measurement information enabling easier, faster and better quality installations.
You can view real-time spectrum information, save the spectral information and view
retrieved spectral information from historic spectrum scans.
Separate information is generated for the HBS and HSUs - all by selection. A general sector
level Highest Interference view is also provided.
RADWIN's spectrum measurement and estimation algorithms are designed to show accurate
information accommodating variations in frequency, temperature and interference power and
at the same time overcoming anomalies that tend to occur in high interference environments.

Who needs it

As indicated in the previous paragraph, Spectrum View is primarily a professional tool for the
technician. The Spectrum View reports may be generated as images, CSV files or text files as
part of the Get Diagnostics feature. All of these are intended for use by to RADWIN Customer
Services to assist with diagnosing interference related problems.

Scope of this Chapter

In view of the nature of the intended audience, we assume that the reader knows about RF
Spectrum Analysis. This chapter therefore, is not a tutorial on RF Spectrum Analysis and is
restricted to showing how to use the Spectrum View tool without any further theoretical
explanations.

Two Ways to Run Spectrum View

Spectrum View may be run from the HBS in which case you have a choice of analyzing all
sites in the sector in one run, or making a selection.
Spectrum View may also be run on a managing computer directly connected to an HSU.
Remember that in such a case the results will be quite different if the HSU is part of a sector
(registered or not) or if it is completely stand-alone, for example using a different spectral
range and operating Band from the HBS. In the former case, expect a "noise hump" around
the channels used by the sector, due to the duty signals from the HBS.
