2.5. IT-100 Range of Application
The IT-100 Analyzer is designed to ensure high-performance 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 for measurement of TV
10

signal level, DVB-C/T/T2/S/S2 and ITU-T J.83 annex A,B,C digital and analog signal
parameters. It also enables measurements of optical signal power and fiber-optic cable
network parameters.
The Analyzer can be used both in laboratory, powered by an external power source,
and in field, powered by batteries.
2.6. Design and Operation Overview
2.6.1. Principle of Operation
The IT-100 Multisystem TV Analyzer is basically a TV signal receiver demodulating
signal to MPEG transport stream. If the transport stream is encrypted, it is restored by a
CAM-module and decoded into TV picture and sound. The input tuner is a double-
conversion superheterodyne receiver with manual and automatic frequency adjustment.
Modulation error ratio MER and constellation diagram are measured during demodulation
of quadrature signal based on vector analysis. Bit error ratio BER in digital transport
stream is measured by means of analysis of operation of noise immune convolutional
codecs. Radio signal measurement is performed by means of conversion of analog RF
signal into digital sequence using ADC and its further processing using signal processor
based on discrete Fourier transformation. The principle of operation of spectrum analyzer
is based on serial or parallel method of analysis with spectrum indication on display.
The resulting image is displayed on LCD in the measurement mode of digital and
analog TV signals reception quality parameters and is basically numerical values and
graphical representation of measured digital parameters (modulation error ratio and bit
error ratio). The constellation diagram mode features vector structure of quadrature
components of demodulated signal with digital modulation in the phase plane. The
spectrum analyzer mode displays the tested signal amplitude to frequency dependence
chart. The TV channel radio signal level measurement mode displays numeric value of
signal level, video carrier to audio carrier level ratio and carrier to noise ratio in the
distribution channel for analog channels or signal power in the channel band for digital
modulation signals.
2.6.2. Component Arrangement
The IT-100 Analyzer is implemented in plastic shockproof sectional housing with
rubber-coated protective elements and includes printed and three-dimensional wiring.
The front panel of the Analyzer consists of a keypad, a graphical display and battery
charge and external power source status indicators (figure 2.2). A loudspeaker (1) and a
fold-out support (2) are located on the rear panel (figure 2.3) of the Analyzer.

4.3.1.3. Navigation
Channel or frequency navigation (depending on the Setting parameter value and the
selected mode) is carried out by the «◄»and «►»keys or alphanumeric keys. To select a
special channel, start its entry with the «.space» key. Press «ENTER» after you complete
17

the number entry. If the channel number entered is incorrect, the previous channel number
will be displayed.
If you use the «◄»and «►»keys in the selected channel plan operating mode
(section 4.3.12.1), tuning will be performed by channels from the plan. Direct entry of the
channel number allows tuning to any channel. If such channel is not listed in the channel
plan, only its number will be displayed on the screen. Channel tuning and numbering is
carried out in accordance with the selected channel allocation standard (channel template)
(section 4.10.2).
4.3.1.4. Checking According to Limit Plan
In the Channel measurement mode the measured parameters are checked for
compliance with the selected limit plan. The green indicator is displayed on the
screen if the parameter values are within the set limits. Otherwise the red indicator is
displayed. Values of measured parameters which are outside the set limits are highlighted
in red. The measured channels outside the channel plan are not checked.
Note. The «Default» limit plan is used by default.
4.3.1.5. Remote feeding power supply
To power external devices, such as, for example, antenna amplifiers, the IT-100
analyzer is equipped with a controlled remote power source. Power from the source feeds
the RF input connector. To set the voltage value, as well as to turn the source on or off, it
is necessary to call the source control mode. To call the mode, press the «Shift» button
and then, without releasing it, press the «/ .space» button. The control mode window
will appear on the screen as shown in figure 4.4:
Figure 4.4
The source control mode is only called from one of the measurement modes. To set
the voltage value from the 5V, 12V or 24V series, use the «◄» , «►»or «F3 / ◄» , «F4 /
►» buttons. Voltage change is only possible when the source is turned off. To turn the
source on/off, press the «F1 / Enable/Disable» button. If the source is switched on, the
current power and current values are displayed in the mode window. If the values are
within acceptable limits, then the background color is green. The green color of the LED on
the front panel of the analyzer duplicates the indication of the power supply to the input
connector. In case of a source failure error detection (there is power on the input of the
analyzer, the power is out of tolerance or the current exceeds the allowable value), the
panel color of the power or current value becomes red, which is also duplicated by the red
light of the LED.
18

If the source is switched off, the value of the voltage that is fed to the input of the
device is displayed in the window. The nature of the voltage is also displayed. The direct
voltage is accompanied by the abbreviation VDC, alternating voltage by the abbreviation
VAC.
To exit the mode, press the «F6 / Close» or «EXIT» button.
