1. GENERAL DESCRIPTION AND PRINCIPLE OF OPERATION
1.1. Introduction
This Operating Manual is intended for introducing the design, functions, and basic procedures
related to operation, maintenance and transportation of CIU-003 TV Signal Analyzer (Analyzer).
CIU-003 Analyzer is designed for continuous monitoring of television and broadcasting
distribution network parameters, as well as of separate components of such networks, or other
electronic devices. Using the Analyzer, you can measure the channel level and parameters of TV
signal with analog and digital DVB-C and DVB-T modulation.
Reliability of CIU-003 Analyzer is ensured by regular maintenance procedures. These
procedures and their intervals are described in Section 5.

CAUTION Tuning the Analyzer and replacement of the components that
influence the accuracy of measurements without service personnel is strictly
prohibited because the components used in the Analyzer are purpose-made and
their replacement will result in inaccurate operation of the Analyzer. You must
observe the Analyzer storage and transportation instructions (see Sections 6
and 7) to exclude the possibility of mechanical damage to CIU-003.
1.3. Function
CIU-003 TV Signal Analyzer is intended for measurement of TV channel parameters and
transfer of measurement results to remote PC via LAN.
