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.

1.2. Safety Precautions
You should 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 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.
5
The Analyzer performs measurement of the following parameters for analog channels: video
signal level, video to audio ratio, and video carrier to noise ratio within the video channel
bandwidth. For digital TV channels the Analyzer measures actual channel power. For DVB-C TV
signals CIU-003 offers the measurement of the following reception quality parameters: modulation
error ratio MER, bit error ratio BER before and after Reed-Solomon decoder. For DVB-T signals
CIU-003 measures modulation error ratio MER, BER after Viterbi decoder and BER after ReedSolomon decoder. Using the Analyzer, you can check MPEG transport stream for compliance with
ETSI TR101290 standard requirements (priority 1 and 2). Also the Analyzer performs analog
channel audio broadcasting (mono) monitoring

1.7. Design and Operation Overview
1.7.1. Principle of Operation
CIU-003 TV Signal Analyzer is a receiver of DVB-C and DVB-T signals with demodulation to the
MPEG-2 transport stream and its further analysis. The input tuner is a triple superheterodyne
receiver with auto or manual frequency tuning. Modulation error ratio MER is measured in the
process of QAM signal demodulation based on vector analysis. Bit error rate BER in digital stream
is determined by means of analyzing the Reed-Solomon and (or) Viterbi decoder operation.
Channel power is measured using analog-to-digital converter after signal peak detection at output
of logarithmic detector of the third IF amplifier.

Analog channel audio broadcasting monitoring performs by measuring demodulated sound
signal with an analog-to-digital converter
1
.
The Analyzer is continuously measuring the channel parameters in the selected channel plan
and according to the selected channel template. The results of digital DVB-C/ DVB-T channel
measurement are values of actual channel power level, MER, BER before and after the ReedSolomon/Viterbi decoder. And the results of analog channel measurement are the values of signal
level, video to audio ratio and video carrier to noise ratio within the video channel bandwidth. The
MPEG transport stream is checked for compliance with ETSI TR101290 standard requirements
(priority 1 and 2).
The measured parameters are stored in the non-volatile memory of the Analyzer together with
the time and date of measurement for each channel. The CIU-003 Analyzer can store up to 80
measurement cycles (one cycle includes measurement of all channels in the channel plan). After
the saved measurement results are transferred to a remote PC with installed ViewRSA software,
the corresponding memory cells become available for saving the next measurement results. Thus
all the measurement results can be stored in the ViewRSA database for any period of time.

After passing the Low-Pass Filter (LPF), the input signal, if necessary, is strengthened by the
Wide-Band Amplifier (WBA) or reduced by the Attenuator (A). Then it is transformed by the doubleconversion TV Tuner (T) into the second 39 MHz IF signal in the level measurement mode or into
the second 36.125 MHz IF signal in the DBV-C/DVB-T signal demodulation mode.

The second IF signal is converted in the Mixer (M) by means of the 28.3 MHz Local Oscillator
(LO) into the third IF signal, and further filtered by 10.7 MHz filter (BPF3), which also determines
the receiver bandwidth.
Logarithmic Gain Amplifier Limiter (LGAL) performs logarithmation and signal detection.
Peak Detector (PD) enables the measurement of the video carrier level by means of Analogueto-Digital Converter (ADC). The digital code of the input signal peak level logarithm is defined as
real value and corrected in accordance with the calibration matrix of the Control Unit (CU)
microcontroller.
From the LGAL limiter output signal is forwarding to the frequency detector with the built in
analog-to-digital converter, and as a result, demodulated and digitalized signal is processed with
the control unit. This allows to perform analog channel audio brouadcasting monitoring
1
.
In digital DVB-C/DVB-T signal demodulation mode the second IF signal is filtered by the
Bandpass Filter (BPF2) and supplied to the DVB-C/DVB-T Demodulator (DD), which performs
demodulation and measurement of signal parameters. The measured results are processed by the
Control Unit.
The Control Unit (CU) uses the Control Interfaces (CI) to support the Analyzer operation with
ViewRSA software and receive the commands entered by the user during the Analyzer
configuration via COM port.
The nonvolatile memory (NVRAM) stores factory calibration coefficients, channel template,
channel plan, limit plan, measurement logs, and service information.
The Mains Adapter (MA) forms the required voltages from an external power source.
1.7.3. Component Arrangement
CIU-003 TV Signal Analyzer is made in 19’’/1U steel shockproof sectional housing that includes
printed and three-dimensional wiring. The Analyzer dimensions are 483x163x44 mm.
The front panel of the Analyzer (see Figure 1.1) has the POWER indicator (index 1) and holes
for mounting the Analyzer on the rack (index 2). The back panel of the Analyzer (see Figure 1.2)
contains a socket for mains supply (index 1), fuse-holder (index 2), mains switch (index 3),
additional grounding connector
(index 4), ETHERNET RJ-45 connector for the Analyzer
connection to LAN (index 5), RS-232 DB-9 connector for setting and updating the Analyzer
firmware from external PC (index 6), label with the device serial number and type (index 7), and
the RF IN input 75 Ohm F-male connector (index 8).
2. PREPARATION FOR OPERATION
Perform external examination to make sure your CIU-003 is free from any visible mechanical
damage.
Upon receipt of the package, check the availability of the items contained in it against the list
provided (see Section 1.5).
If your CIU-003 has been kept in the environment other than the rated operating conditions,
leave the Analyzer in facilities with normal operating conditions at least for 2 hours prior to
operation.
If the Analyzer is going to be used in laboratory (without mounting into the rack), fix 4 rubber
mounts into the holes of the Analyzer housing base.
