1. Introduction
The TSW500CATV is an equipment for measurements of signals cable TV quickly
and efficiently. It gets information on the channels of the carriers and has a spectral scan
mode; it detects the presence of interference beats as well as the amplitude of the
carrier. The equipment allows the power measurement of QAM signals, constellation
diagram, measurements of pre and post BER and MER and a voltmeter. The
TSW500CATV has a plastic shield that makes it resistant to impact; it is lightweight and
has a simple and practical keyboard that makes possible the operation with only one hand.
1.1 TSW500CATV Characteristics
The TSW500CATV is a portable equipment protected by a plastic enclosure, it is
operated through a keyboard and a liquid crystal display, besides it has an LED to indicate
the battery charge. The equipment is powered by an internal battery pack must be charged
using the original source.
The following tests may be done:
Channel test;
Frequency test;
Tilt;
Full Scan;
Ingress Test;
Voltmeter.
