2. GENERAL DESCRIPTION AND PRINCIPLE OF OPERATION
2.1. Introduction
This Operating Manual is intended for introducing the design, functions, and basic
instructions related to operation and servicing of the IT-088 Digital DVB-T Signal Analyzer
(Analyzer).
The IT-088 is designed for control and adjustment of television and broadcasting
distribution networks as well as of separate components of such networks, or other
electronic devices. The Analyzer allows measurement of channel power and parameters of
TV signal with analogue and digital (DVB-T/H standard) modulation.
The Analyzer can be used both in laboratory, powered by an external power source,
and in field, powered by batteries.
The reliability of the IT-088 is ensured by fulfillment of regular maintenance procedures.
These procedures and their intervals are described in section 5.

2.2. Safety Precautions
Thoroughly inspect the product and carefully read the related documentation to get
acquainted with all the safety markings and instructions before you start to operate the
Analyzer.
WARNING Only trained service personnel aware of the hazards involved
should perform repair on the Analyzer.
CAUTION Tuning the Analyzer and replacement of the components that
influence the accuracy of measurements without service personnel is
strictly prohibited, since the components used in the Analyzer are purpose-
made and their replacement will result in inaccurate operation of the
Analyzer. To exclude the possibility of mechanical damage to the IT-088,
the instructions regarding the storage and transportation (see sections 7
and 8) of the Analyzer must be observed.
