Overview
The Emitor Combolook Color HD is a Swedish designed Satellite TV/CATV instrument
and spectrum analyzer. The unit was designed for the exact alignment and adjustment of
satellite dishes, terrestrial antennas, as well as trouble-shooting and quality control of
MDU systems layout including CATV networking.
This instrument was designed for the professional when accurate and precise information
is needed. With ease of operation through powerful processor technology, basic
operation is achieved with only a few controls. The functions are easy to access and only
take minutes to learn. Many functions can be controlled by the enclosed Remote
control.
A 5 inch 16:9 color TFT-LCD display is provided which shows either normal “Free to air”
satellite TV channels in Analog or DVB-S, CATV Analog and Digital channels, the
frequency spectrum or a Constellation diagram and digital information regarding the
signal.
Menus and help displays are shown on the LCD screen (64x128) beside the monitor and a
keypad is used for the function selection. The knob is used for frequency and other
operations. A remote control is provided which allows most of the keypad commands to
be used to control the instrument.
The Combolook functions as both an instrument for use in Satellite and terrestrial TV or
CATV. The mode of operation is selected at power on, and to conserve battery life only
the necessary functions are enabled. Switching modes can be done at power on or by
menu selection.
Satellite Instrument Mode
The Spectrum shown enables the measurement of the satellite spectrum in resolution
steps of 1 MHz to 10 MHz making it easy for the skilled installer to know what satellite
he is receiving and make more detailed measurements. The Spectrum function spans the
frequency band 920-2150 MHz and can be expanded from 4 MHz down to 1 MHz steps.
Automatic frequency conversion to the user defined LNB type is shown on screen so no
calculations are needed to determine the Satellite frequency. Cross polarization at a
frequency can be easily checked with the cross polarization function. The instrument has
high resolution for accuracy. It presents measured data ±2 dB (at 20o C). Frequency
tuning is done with the main knob in frequency steps between 4 MHz and 1 MHz
depending on the span of the spectrum. When the spectrum is displayed, Automatic
Spectrum Identification is provided by accessing the NIT information by hunting for a
DVB-S signal from one of the transponders. The Analog Picture mode can display a
multistandard PAL, NTSC and SECAM picture and accepts audio frequencies between 5.5
and 8.5 MHz. Analog pictures can be viewed either directly using the spectrum as a
guide, or recalled from 100 user defined memory positions.
The Digital Mode shows extended information of Modulation, SIG, SNR, BER, MER, and a
constellation diagram. The Satellite Name and position are shown using the Network
Information Table in the MPEG transport stream. Channel detail (or Service Information)
can also be displayed for a transponder if needed.
4
The user memory positions can save spectrum displays, analog channels, digital channels
and Saved spectrum positions can be mixed simultaneously with an actual reading for
easy comparison and control of signal-levels. Measurements on group of channels can
be made with up to 10 frequencies simultaneously with automatic polarization and band
selection.
For Universal LNBs, the polarisation V/H is switchable by 13/18V and Lo/Hi band with 22
kHz-tone.
The instrument features circuitry protection to prevent short circuits during connection
of the LNB.
The DiSEqC function controls all DiSEqC accessories such as switches and positioners.
TV Instrument mode
The Spectrum is shown from 2MHz to 900MHz and can be zoomed to smaller segments
(minimum 13MHz span) for closer inspection. In TV mode, it presents measured data ±1
dB (at 20o C). The Combolook Color HD is capable of working with the return-path
signals in Cable-TV networks (5-65 MHz) according to the EN50083 standard. Signal to
Noise measurements and Digital Channel power measurements can be made using
Reference markers on the spectrum.
Analog TV pictures can be displayed with sound and attenuation inserted from 0-45dB to
determine picture quality with increased attenuation. TV Channels can be saved as
favorites for easy tuning.
DVB-T MPEG-2 digital transmissions can be viewed to check signal quality.
The Combolook Color HD is powered by a built- in, rechargeable Li-Ion battery. The
battery can be recharged using either the included external battery charger or the caradaptor.
The Combolook Color HD weighs less than 4kg including the battery and the carrying
case.

Spectrum Operation (Satellite)
The Spectrum Mode is displayed when the instrument is turned on in Satellite mode.
With a dish and LNB connected, it will show a display similar to that above. The
spectrum is displayed with the Start frequency at the top of the screen and the Stop
frequency at the bottom. The Span is the total frequency coverage or the difference
between Stop frequency and Start frequency. The current signal level (14.3 dBmV in this
example) is displayed for the frequency at the Marker. The knob is used to change this to
the frequency of interest.
When Spectrum Mode is entered, the peaks are checked to see if the demodulator can
lock. If a lock occurs, the NIT data for the transponder is displayed for automatic
satellite identification. NIT data on a transponder is repeated at least every 10 seconds
and on most satellite more often than this.
The span of the Spectrum can be changed in two ways. Pressing the keypad ‘3 Span’ will
change the spectrum to the minimum span of 250MHz. For this span, each division is
1MHz. An alternate method is to use the adjustable span. Pressing the knob allows the
span to be adjusted from a minimum of 250MHz to the maximum of 1231MHz. At this
maximum span, the entire IF band from 920MHz to 2150MHz is displayed.
When span is adjusted by pressing the knob, a second press of the knob allows the “DC
Offset” of the spectrum to be adjusted for best display. A further press of the knob
restores the operation to frequency adjustment. The span setting from the knob remains
as the current setting. The “DC Offset” is restored to 0.
The current band being displayed can be changed with the 22kHz signal using the
keypad ‘# 22kHz’. For Universal LNBs, when the 22kHz is off, the band is Lo Band
(920MHz to 11900MHz) and when the 22kHz is on, the band is Hi band (11520MHz to
2150MHz) There is a small overlap from 11520MHz to 11900MHz, so a Universal LNB
can tune this range with 22kHz either on or off.

Digital Mode (Satellite)
This shows a typical constellation from a DVB-S QPSK signal. The frequency and offset
are shown below the constellation diagram and the measured symbol rate is shown
below the frequency. The two thermometer bars show the BER and SNR of the signal.
The SNR thermometer increases from right to left and the BER thermometer gets smaller
from right to left, so that the best signal is shown by a longer white bar.
The lock time is shown at the top right and below this, the signal modulation and FEC.
The MER (Modulation Error Ratio) and the Output Bit Rate for the total transport stream
is also show.
When the NIT information is available, the NIT name and NIT Orbital Position appear.
Reading the SDT data shows the number of “Free to Air” channels.
A running count of the CB (Corrected Bit) and UCB (Uncorrected Block) errors is shown
as long as the signal is locked.
12
Digital Mode Functions (Satellite)
Search +/+/-) A signal search can be initiated by using the keypad ‘1 Search +’ to search
with increasing frequency or ‘2 Search –‘ with decreasing frequency. The search mode
moves to the next peak in the spectrum and attempts a lock for DVB-S QPSK, DVB-S2
QPSK and DVB-S2 8PSK signals. The symbol rate is determined automatically. Because
the time to lock for low symbol rate signals increases the lower the symbol rate, symbol
rate signals below about 16000 will not lock during a search.
Memory) Frequencies are stored in the Digital memory. (See Memory page 13)
Channels) When a signal is locked, the Digital services from the SDT Service Information
will be displayed on the TFT screen.

16
Memory Functions (Satellite)
There are four different user memory types in the Combolook Color HD instrument.
They are divided according to the type of data storage required. Each memory area is
chosen automatically depending on the type of data.
Spectrum Memory: There are 100 memory positions reserved for User data of the
spectrum waveforms. This data can be loaded and viewed or mixed with the current
signal for comparison.
Analog memory: There are 100 memory positions reserved for User data of Analog
frequencies. Each position stores the Name, frequency, 13/18V, and 22kHz state.
Digital Memory: There are 100 memory positions reserved for User data of Digital
frequencies. Each position stores the Name, frequency, 13/18V, and 22kHz state.
Digital Channel Memory: There are 100 memory positions reserved for User data of
Digital Channels. Each position stores the Name, Service ID, frequency, 13/18V, and
22kHz.
Text Editor (Satellite)
All the User memory areas use the Text Editor for saving the name for the memory
position. With the Digital Channel memory, the current channel name is entered from
the SDT data and usually this name is correct and all that is required is to save the name.
With the other memory positions, a name requires manual entry. Use the knob to select
the characters from the list and the knob select button to enter the character. Characters
can be deleted by using the keypad ‘1 Delete’ and the current position can be changed
by the keypad ‘2 Left’ or ‘3 Right’. The keypad ‘* Save’ completes the entry and saves the
name to the memory position.
17
DiSEqC Functions (Satellite)
The Combolook Color HD instrument supports all usual DiSEqC commands for the
DiSEqC specifications 1.0, 1.1 and also supports the Goto X function for easy positioner
movement. The DiSEqC commands can be accessed from several menus for
convenience.
From the Spectrum Mode: keypad ‘5 DiSEqC’
From the Digital Mode: keypad ‘5 DiSEqC’
From the Multichannel Mode: keypad ‘ 8 Spec’, keypad ‘5 MultiCH’, keypad ‘5 DiSEqC’
In the DiSEqC menu, the DiSEqC commands LNB1, LNB2, LNB3, LNB4 as well as Tone
Burst A and Tone Burst B can be sent.
For Switches, the SWx command allows the switch commands SW1 up to SW16 to be
sent.
The Motor command allows the operation of positioners. Go East and Go West move the
positioner as long as the key is pressed. Calibrate moves the positioner to the home
position, usually due south. Limits allow “soft” limits to be set or cleared for the
positioner. Position allows the setting a movement to defined positions, The Go East
command and Go West command are used to move the positioner to an optimum
position, and then that position is saved from 1 to 31. (Goto position 0 commands the
positioner to its home position.)
The Goto X (also called USALS) command removes the necessity to find positions
manually. To use the Goto X function, the instrument latitude and longitude must be
known. Once these are set, they are stored in permanent memory and so will not be lost
on power down. Once the latitude and longitude are correct, the positioner can be
commanded to move directly to a satellite orbital position.
18
Setup (Satellite)
The Setup menu contains the functions which are used
infrequently.

19
Special Functions (Satellite)
MaxHold) This sets the measurement of signal level to hold and
display the maximum received values. Once enabled, the
measurements will remain in MaxHold until expressly disabled.
Refmrkr) The Reference marker allows a second marker to be
placed on the spectrum display. Adjust the marker to the required
second location and set the reference marker. Now when the
marker is moved to another location on the spectrum display, the
difference in dB level and the frequency difference are displayed.
Span Min/Max) The span can be changed when on this menu for
convenience. It is the same as the span setting on the Spectrum
menu.
Memory) Samples of spectrum data can be saved in memory and
then either displayed or mixed with the current spectrum. When the mix function is
chosen, the current spectrum is adjusted to the same span and starting frequency, and
then the spectrum from memory is overlayed as a line image so that you can compare the
current signal with a saved spectrum.
The spectrum memory is selected using the knob and the memory position is displayed
on the TFT. Spectrum memory can be loaded for examination as well as mixed.
20
Atten) The 15dB attenuator can be inserted or disabled from this menu.
13/18V) The 13V/18V LNB voltage can be changed at this menu for convenience.
22kHz) The 22kHz LNB signal can be changed at this menu for convenience.
21
UniCable LNB Functions (Satellite)
When a UniCable LNB is first connected, there will be no signal. This is because in the
Spectrum mode, no UniCable commands are issued. Command the UniCable LNB by
switching to the Digital mode and back to the Spectrum mode and it will show a
spectrum. (Turning on and off the LNB 13/18 or the LNB 22kHz will also command a
UniCable frequency.) The span of the spectrum can be set to either 250MHz or
1231MHz (the maximum or minimum) by pressing the keypad ‘Span’. The Marker
frequency shows the IF frequency of the User Band. The translated UniCable signal will
be at the chosen User Band and about 100MHz wide. For the UniCable LNB, the LNB
13V/18V and the LNB 22kHz signal represent the Polarisation and the Band and are not
sent to the UniCable LNB. In the Digital mode, the frequency shown is the UniCable
commanded frequency.
Remember that the displayed UniCable band is reflected in frequency about the User
Band frequency as shown in the example below. For more details see Appendix D.
User Band 1
10936 MHz
10906 MHz
10878 MHz
22
The UniCable test (Spec -> UniCable -> Uni Test) allows full testing of a UniCable LNB.
This test takes about 20 seconds to check each User Band. During the test, the four User
Bands are identified and any offset found is used for further UniCable tuning.
User Band 1
1210 MHz
User Band 2
1420 MHz
User Band 1
1680 MHz
User Band 1
2040 MHz
At the end of the test, the results of measuring the User Bands are presented.
The User Band is set to 1 by default, but for more detailed testing it
can be set to any of the four bands, for Example: Spec -> UniCable
-> UsrBand 4. Now User Band 4 will be used for any further
UniCable Tuning.
23
Spectrum Operation (TV )
When the Combolook Color HD is first turned on in TV mode, the spectrum is displayed.
Upon connection of an aerial or CATV source, it will show a display similar to that above.
This portion of a spectrum shows a digital TV signal and an analog TV signal at the
marker frequency. The spectrum is displayed with the Start frequency at the top of the
screen and the Stop frequency at the bottom. The Span is the total frequency coverage
or the difference between Stop frequency and Start frequency. The current signal level
(53.3 dBuV in this example) is displayed for the frequency at the Marker. The knob is
used to change this to the frequency of interest.
The span of the Spectrum can be changed in two ways. Pressing the keypad ‘3Span’ will
toggle the spectrum to the minimum span of 13MHz and the maximum span of 900MHz.
For this minimum span, each division is 50 kHz. An alternate method is to use the
adjustable span. Pressing the knob allows the span to be adjusted from a minimum of
13Mhz to the maximum of 900MHz. At the maximum span, the entire IF band from
2MHz to900MHz is displayed.
When span is adjusted by pressing the knob, a second press of the knob allows the knob
to control the insertion of attenuation from 0dB to 45dB as indicated on the display. “DC
Offset” of the spectrum to be adjusted for best display. A further press of the knob
restores the operation to frequency adjustment. The span setting from the knob remains
as the current setting. The “DC Offset” is restored to 0.
The current video bandwidth (VBW) and Resolution Bandwidth (RBW) are shown. These
can automatically or manually set in the Setup Menu.
In the LCD display, the knob function (FREQ, SPAN, ATTEN) is shown and also shown is
the status of the Power Inserter to use with amplified antennas.
Picture) Displays an analog PAL/NTSC/SECAM picture at the marker position frequency.
See Analog Picture Mode (TV) page 25.

Digital Picture (TV)
The DVB-T module is controlled by the keypad with the keys representing screen
directions. (Alternatively, it can be controlled by the remote handset.) When the DVB-T
module is first started, the initial parameters will need to be set. The menu language can
be set to English, Swedish, Finnish, French, German, Danish, Romanian, Dutch, Polish,
Slovenski, Spanish, Latvian, Russian, or Indonesian. The subtitle and Time Zone settings
are not important and the default for Screen Mode of “16:9 Center” is best. The
Antenna Power setting here is not used. If an amplified antenna is being used, then
adjust the voltage using the Power Inserter Menu (Setup -> P-insert Menu).
If there are no channel settings stored it will need to search for channels. Press OK to
enter the Search menu from the main Menu screen.
29
The Search can be done automatically for all frequencies (50.5MHz-858MHz) or by using
the up, down, left and right buttons can be made on a specific channel. The Frequency
for the channel is shown but cannot be adjusted. The bandwidth default is set at 7MHz.
Change this if the DVB-T signal has a different bandwidth. (In automatic searching
bandwidth is set automatically.) The Priority default is “High”. (In automatic scanning,
both low and high priority streams are searched.)
The channels found during the search are displayed as they are found.
Once the channels are found, the DVB-T module will tune to the last channel viewed on
startup.
30
Setup (TV)
The setup menu contains the items which are infrequently used.
Lcd) The LCD contrast can be adjusted and the LCD backlight
enabled or disabled.
Display)
Display) The scan cursor in the TV spectrum can be enabled or
disabled. The Spectrum Graticule can be turned on for dB
guidelines. The display units for signal level can be set to dBuV,
dBm, or dBmV. The TV Level can be adjusted from 55 dB to 75 dB.
This is the level that the Combolook uses for automatic attenuation
for TV presentation.
P-insert) The supply voltage on the antenna can be selected when
using an active antenna. Ensure you know the correct operating
voltage of the antenna amplifier because supplying too high a
voltage could burn out the active device. The voltage can be adjusted from 0V (off) to
between 12DCV and 24DCV. The positive supply is the BNC Center terminal. The
selected output voltage is always visible in upper left hand of the LCD display (next to
the battery-symbol). The default setting of “P – insert” is “Off” (0 volt).
Warning ! Misuse of this function may cause irreparable damage to all connected
equipment not intended to accept or receive voltage !
CH_Table) This selects the Channel Table in use to display and select the frequency. The
available channel tables are: CCIT, France, Poland, Italy, UK1, UK2, UK3, South Africa,
and Australia. Details for these channel tables are shown in Appendix E.
Vid BW) The Video filter is placed after the measuring chip-set in the instrument, and is
used in conjunction with various resolutions within a specified bandwidth. The resolution
of details on a signal-carrier is progressively refined in relation to the narrowing of a
filter ( sweep-time is increased). The different Video filters are: auto-mode (default),
100 kHz, 10 kHz, 1 kHz or 100 Hz.
Res BW) The resolution bandwidth shows the incoming signal before the measuring chipset in the instrument. Choose between the narrow 300 kHz or the wider 1 MHz
resolution. The instrument is normally working in the ”auto
auto”
auto mode.
AM Marker) Choose between FM or AM marker. FM = Normal spectrum measuring.
AM = Peak spectrum measuring which is preferable when measuring TV signals due to
the speed at which calculations are processed.
SAT/TV) The instrument mode when turned on can be selected to start either in TV
mode or Satellite mode. A third option is available which will ask the user on startup to
select the mode. If no selection is made within 20 seconds, the instrument will turn off.
Version)
Version) The version menu displays serial number, levels of the firmware and related
information.

Signal-to-Noise Ratio Measurements (TV)
The Combolook Color HD is capable of performing measurements of the Signal/Noise or
Picture-Carrier/Audio-Carrier ratio.
To perform these measurements:
• Put the marker on any signal carrier and ”zoom in” with the ”Span
Span 13 ” button.
• Push Ref mrkr,
mrkr for the reference marker setting.
• Tune in the ”right” frequency with the marker so that it is a the peak of the signal
to measure.
• Push Ref set and a new marker appears on top of the first marker.
• Turn the knob and place the reference marker on another carrier (signal peak), or
on the noise-floor.
• The relation between the first marker and the second marker is presented in the
lower right hand corner of the picture-screen so in the spectrum below we see
that the audio carrier is 7dBuV lower that the picture carrier and the video/audio
carrier spacing is 5.5MHz.
This measurement can also be made from Spectrum samples saved in memory. After a
spectrum is loaded from memory with “Memory -> Load” choose” Ref mrkr” and use the
knob and set the first marker position with “Ref set” and then use the knob to define the
second reference marker.
32
Channel Power Measurement (TV)
The digital output-level (in dB) of digital transponders (such as in digital terrestrial
transmissions) can be measured for saved spectrum samples.
(If the spectrum is not saved, then save the spectrum to a memory location by “Memory > Spectrum -> Save” )
Load a saved spectrum using “Memory -> Spectrum” and use the knob to select the
memory position and then press “Load”.
Press “Digital” and now use the knob to set the start frequency of the digital channel.
Press “Set strt” and then use the knob to set the stop frequency and press “Set strt” again.
(Digital transponders are normally 8 MHz wide)
The channel power and bandwidth are shown at the lower right of the TFT screen.
33
Using PC to transfer transponder data
Satellite transponder data can be loaded from the instrument to and from a PC for easy
changes. The Windows PC program used is chedit.exe. From the File Menu, a channel
file can be loaded from the Combolook, edited and saved back to the Combolook. Also
channel files can be loaded and saved on the PC for backup and easy updates of channel
files.
34
Loading Firmware
Loading new firmware to the Combolook is done using a Windows loader program called
“FDLDVB.exe”. Also needed is the firmware hex file to load. In the Combolook, there are
two different types of firmware used. The main control firmware will have a name like
“CL-HD-10” and the DVB module firmware has a name like “SC_DVB_1.3.bin”. Usually it
will be necessary to only update the main control firmware. Do not load any firmware
without these types of name, it will be for a different instrument and will not work on the
Combolook Color HD. Use the Version screen in the Setup Menu to determine the
current software version.
In order to load firmware, you must have a PC which supports an RS232 connection. The
firmware loading must be performed with the external charger connected. The RS232
cable to be used is supplied as part of the kit with the Combolook Color HD. Some
laptops do not have an RS232 connection, but a USB to RS232 adapter can be purchased
at low cost. Connect the Rs232 cable from the computer to the instrument. Run the
firmware download file “FDLDVB.exe”.
Select the RS232 port on the computer. Normally, the port is COM1 but some USB to
RS232 will use some other port. If desirable, this USB to RS232 conversion device can be
made to always use COM1 by clicking Control Panel / Device Manager / Ports and in the
Advanced settings for the adapter set to COM1.
Select “Send Satlook Firmware” and then “OK” and the display will show “Searching”.
Connect the Combolook Color HD to the external charger and the display will change to
a file dialog to choose the firmware file.
35
Normally, the firmware will be in the same direction as “FDLDVB.exe” but if not, you can
navigate to the correct directory and select the firmware file. Once the file is selected,
the firmware loading will take about 10 minutes and then the Firmware Downloader
program will display “Download Complete”.
The DVB module firmware will probably not need updating, but if it does, then choose
the “Send DVB Firmware”. The loading process for this firmware is different. Power on
the Combolook and wait until it is fully started.
Once a firmware file is selected, download will begin and take about 25 minutes.

Appendix A – Universal LNB Primer
The LNB (low noise block amplifier) has evolved since its early introduction in Satellite
broadcasting. Signals broadcast from satellites are 10600 MHz to 12700 MHz for Ku
band and 3000 MHz to 4500 MHz for C band. Because the losses in coax are quite high
for these frequencies, the satellite signal is first downconverted to a more manageable
950 MHz to 2150 MHz for transmission from the dish to the receiver. This is called the IF
(intermediate frequency) or also the L Band. Most of the European broadcasting is in the
Ku band. The satellite transmission can use either horizontal or vertical polarisation. This
is a way of re-using the available spectrum since there can be two transponders at the
same frequency with different polarisations. The Universal LNB can receive either
horizontal or vertical polarisations depending on the LNB line voltage. 13V is used to
select Vertical polarisation and 18V is used to select Horizontal polarisation.
The Ku band for satellite reception is 2100 MHz wide (12700 – 10600) while the receiver
input is only 1100 MHz wide (2150 – 950). To allow the full reception of the entire Ku
band, two different local oscillator (LO) frequencies are used in the Universal LNB. This
LO frequency is switched in the Universal LNB by using the 22 KHz tone. When it is off,
then the LO frequency used is 9750 MHz and when on, 10600 MHz is used.
The four frequency ranges for the Universal LNB are sometimes called quadrants and is
diagrammed below showing the overlap.

Appendix B – DiSEqC Primer
About DiSEqC
DiSEqC is an acronym for “Digital Satellite Equipment Control” and is achieved using the
22kHz signalling tone. The 22 kHz signal is imposed on the LNB DC voltage of 13V or
18V at a level of 0.65V p-p. Normally, the 22kHz signal is either continuously on or off.
When a DiSEqC message is to be sent, if the 22kHz is on, it is turned off for a “quiet
period” before the message. Then the DiSEqC message is sent as a series of bytes with an
odd parity bit appended. The bits are formed by modulation of the 22kHz signal as
shown below.
Most DiSEqC commands are 3 bytes in length but some can be up to 6 bytes long, so the
transmission time of a DiSEqC message is on the order of 40 to 80 milliseconds.

Appendix C DVB-S and DVB-S2 Primer
DVB-S and DVB-S2 both use phase shift keying to digitally modulate a carrier.
Quadrature phase shift keying is used in both and the digital data is encoded as a 90
degree phase shift in the signal. This gives 4 possible states for each sampling interval.
The sampling interval is called the Symbol Rate and each state of 2 bits is a Symbol.
During transmission, this data is interleaved to allow recovery during noise bursts and
redundant data is added called FEC (forward error correction). During reception, the
data is re-shuffled to restore the order and the FEC data is used to correct the bitstream
as necessary. In DVB-S2, 8PSK (octal phase shift keying) can be used in transmission
where there are 8 possible states from a 45 degree phase shift in the Analog signal. A
different scrambling and FEC for DVB-S2 allows better noise immunity.
The bitstream output for both DVB-S and DVB-S2 is the same. This bitstream is called
“transport stream”. A transport stream is made up of packets. All packets are the same
length of 188 bytes and they all start with the sync byte 0x47 so that when the data is
read, a starting point can be located. Each packet also contains a PID (packet
identification). The information in the transport stream consists of several video and
audio streams and also SI tables (Service Information) to allow the receiver to decode
and display the correct data. There are several types of tables in the SI called PSI data.
This table data is generally longer than one packet so several packets are assembled
together to make a “section” which can be up to 1024 bytes.
1) Program Association Table (PAT): for each service in the multiplex, the PAT indicates
the PID of the corresponding Program Map Table (PMT). It also gives the location of
the Network Information Table (NIT).
2) Program Map Table (PMT): the PMT identifies and indicates the PIDs of the video,
audio, and other streams that make up each service.
3) Network Information Table (NIT): the NIT gives the Network Number, Name and
Satellite Position of the satellite. It also lists all the other transponders on the satellite.
4) Service Description Table (SDT): the SDT gives information about each service in this
transport stream.
Once these tables are decoded by the receiver, the correct PID for the audio and video
streams can be found and presented to the video and audio decoders. In DVB-S, the
video streams are presented in MPEG-1 or MPEG-2 encoding (usually MPEG-2). For
DVB-S2, the video streams can be presented in these formats or in the newer HD format
MPEG-4.
(For a more complete understanding, see ISO 13818-1 “Information technology, Generic
coding of moving pictures and associated audio information: Systems” and DVB EN 300
468 “Specification for Service Information”)

Appendix D UniCable Primer
UniCable or SCIF (Single Cable Interface) is a method of translating Satellite frequencies
from the LNB to the user. It is intended to allow multiple receivers to share the same
coaxial cable.
With a standard Universal LNB, with Horizontal and Vertical polarity and low and high
band, there are four frequency ranges that can be selected from the LNB by using the
13V/18V and the 22kHz signal. In order to allow multiple receivers to operate using a
single coax cable, UniCable operation requires the receiver to send the desired
frequency using a DiSEqC command. A UniCable LNB or Switch may be used. For a
UniCable Switch, the LNB input is usually a Quattro LNB which provides the four
frequency ranges to the switch. For a UniCable LNB, the Switch and the Quattro LNB are
integral.
To tune a frequency on the UniCable LNB (or Switch), the receiver issues a DiSEqC
command which indicates the Satellite Frequency needed, the Polarisation, the Band and
what User Band to use. The number of User bands differs but normal is 4 or 8.
The User Bands which are available can be determined by sending a DiSEqC command to
emit RF tones at the centre frequencies of the User bands. By scanning the frequencies,
the User Bands are located. To find out what number User Band this is, another DiSEqC
command is sent to turn off the tone at User Band XX. By selectively turning the RF tones
off, the number of the User Band is determined. Alternatively, The User Band Frequency
allocation is usually provided on the LNB/Switch description. The placement of the User
bands within the spectrum is not the same between manufacturers.
For further detail on UniCable, see the specification EN 50494 – Satellite signal
distribution over a single coaxial cable in single dwelling installations.

Appendix F – DVB-T Principles
DVB-T uses OFDM (orthogonal frequency division multiplex) modulation. This type of
modulation, which uses a large number of sub-carriers, delivers a robust signal that has
the ability to deal with very severe channel conditions. The DVB-T standard has
technical characteristics that make it a very flexible system: 3 modulation options (QPSK,
16QAM, 64QAM), 5 different FEC rates, 4 Guard Interval options, 2k or 8k carriers
(actually this is 1705 carriers or 6817 carriers), 6, 7 or 8MHz channel bandwidths
One other technical aspect of DVB-T is its capacity for Hierarchical Modulation. Using
this technique, two completely separate data streams are modulated onto a single DVB-T
signal. A "High Priority" (HP) stream is embedded within a "Low Priority" (LP) stream.
Typically, the LP stream is of higher bitrate, but lower robustness than the HP one.
Receivers with "good" reception conditions can receive both streams, while those with
poorer reception conditions may only receive the "High Priority"stream.
After the MPEG transport stream (usually called MUX instead of transport stream) is
demodulated, then the data encoding is the same as DVB-S as explained in Appendix C.
For further information see the DVB-T Standard published as EN 300 744 and ETSI TS
101 154, Specification for the use of Video and Audio Coding in Broadcasting
Applications based on the MPEG-2 Transport Stream.

Appendix G- Maintenance
The instrument is equipped with a rechargeable battery and it is important that the
battery is maintained. Recharging should be done using the included car adaptor or
external power supply. (110-220V/14V DC, center-pin positive and chassis earth)
Please note that instrument can be operated, for shorter periods of time, by the external
power supply, however, the Combolook Color HD is not made for permanent operation
with the external power supply. This will degrade the battery. Contact your dealer for
more information.
Adjustments for vertical hold, brightness and contrast are located under the instrument.
Contact your dealer for proper adjustments.
The battery needs recharging when the battery symbol at the top of the LCD appears
empty. For protection of the battery, when the battery voltage falls to an unsafe level,
“BATTERY EMPTY” is displayed on the LCD and then the instrument turns off. Remember
that a cold battery has much lower capacity than one at room temperatures. The
Combolook Color HD is designed for outside use in rough conditions but it should not be
exposed to rain or snow as this can damage or shorten the lifetime of the instrument.
Checking/charging the battery:
Because the instrument has been stored for some time before transportation it is
important to check the battery-condition. To do this turn the main switch On.
When starting the instrument, the LCD color monitor and LCD display turns On.
There is a battery symbol at the top of the LCD display that shows the status of the
battery. All black means that the battery is fully charged. If the symbol is empty it means
that the battery is nearly completely discharged.
If the battery needs recharging, use the power supply included with the instrument.
A thermometer scale (0-100%) is displayed on the LCD as the recharging starts.
Please note that the instrument should be turned off when being recharged. Charging
will not be performed with the instrument is on. Recharging from fully discharged
battery to about 98% capacity takes approximately 30 hours. When the battery been
recharged the Combolook Color HD is ready to be used.

Glossary
8PSK:
8PSK (8 Phase Shift Keying). This is the modulation type that is used for DVB-S2 also
called HD. In 8PSK, a symbol has 8 states or 3 bits. On the constellation diagram, an
8PSK signal either be “Normal”, with the eight points around a circle centred on the
origins or “Rotated” 22.5 degrees.
Attenuator: The attenuator inserts an active resistance into the RF path and reduces the
signal level about 3 dB.
BER:
BER (Bit Error Ratio) This is the ratio of BitsError/ BitsReceived This is a small number and is
usually expressed in scientific notation as BER = 2 X 10-8. Typically, BER should be smaller
than 1 X 10-6 for good reception.
dB: (decibel) The decibel is a logarithmic ratio of voltage (or power) to a standard or
reference voltage (or power).

FEC: (Forward Error Correction) This is the error control used in DVB and other systems
to correct errors in transmission. To do this, the data is sent with additional error
correcting bits. On reception, the error bits are identified and (usually) corrected.
HD:
HD: (high definition) This refers to any resolution above the DVB standard resolution.
The DVB standard resolutions for the luminance signal are (H X V):
720 X 576, 544 X 576, 480 X 576, 352 X 576, 352 X 288
The DVB-S2 High definition resolutions are (H X V) 1920 X 1080 or 1280 X 720. They
can either be interlaced or progressive. Interlaced means the picture is built from two
“fields” with each field being alternating half the scan lines. Progressive means the
entire picture is repeated each time. Progressive pictures require a higher data rate.
IF:
IF (intermediate frequency) This refers to the frequency after down conversion at the
LNB to the range 950 MHz to 2150 MHz.
IQ decision points:
points During demodulation of a QPSK or 8PSK signal, the two phases of the
are converted to digital data and this data is sampled at the Symbol Rate. These samples
are called IQ decision points (as seen on the constellation diagram) and are then form
the digital input symbols.
LNB: (Low Noise Block) The general name for the amplifier and downconverter at the
dish.

MaxHold: In the Analog Mode, this can be used to “remember” the highest peak of the
RF signal.
MER: (Modulation Error ratio) This is usually expressed in dB. It is calculated from the
constellation pattern and represents how close the I and Q decision points are to the
ideal position. A typical MER value is 16 dB.
NIT: (Network Information Table) One of the System Information (SI) tables in DVB
containing the current satellite name, position, and other data.
P-insert: (Power Insert) This function is used for powering external, active accessories
(such as antenna amplifiers) which require a power-source in order to operate. The
output voltage may be adjusted between 12 - 24 volt DC and is connected via the BNCconnector. The selected output
output voltage is always visible in upper-left-hand of the LCDdisplay (next to the battery-symbol). The default setting of “P – insert” is “Off
Off”
Off (0 volt).

QPSK: (Quadrature Phase Shift Keying) This is a digital modulation used for all DVB-S
transmissions. The data is transmitted depending on the phase of the signal with 90
degrees the shift, so four states (one symbol) are encoded at each Symbol Frequency.
QPSK HD: DVB-S2 transmissions can be broadcast in either 8PSK modulation or QPSK
modulation, When the demodulator receives a DVB-S2 transmission in QPSK, then QPSK
HD” is displayed.
Res BW: (Resolution Bandwidth) The resolution bandwidth shows the incoming signal
before the measuring chip-set in the instrument. Choose between the narrow 300 kHz or
the wider 1 MHz resolution. The instrument is normally working in the ”auto
auto”
auto mode and
the bandwidth chosen is shown on the spectrum display.
SNR: (Signal to Noise Ratio) The SNR of a Signal is a measure of the quality of the signal
in dB and higher SNR is better. Typical SNR readings for a clean signal will be greater
than 10.0 dB. This is a measurement from the demodulator and is only valid when the
received signal is locked.
Vid BW:
BW: (Video Bandwidth filter) The Video filter is placed after the measuring chip-set
in the instrument, and is used in conjunction with various resolutions within a specified
bandwidth. The resolution of details on a signal-carrier is progressively refined in
relation to the narrowing of a filter ( sweep-time is increased). The different Video
filters are: autoauto-mode (default), 100 kHz,
kHz 10 kHz,
kHz 1 kHz or 100 Hz. The bandwidth in use
is shown on the spectrum display.
