Overview
The Emitor Combolook Color HD is a Swedish designed Satellite T /CAT 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 CAT 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 T channels in Analog or D B-S, CAT 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 T or
CAT . 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 20
o
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
D B-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.

5
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 /H is switchable by 13/18 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.
T Instrument mode
The Spectrum is shown from 2MHz to 900MHz and can be zoomed to smaller segments
(minimum 13MHz span) for closer inspection. In T mode, it presents measured data ±1
dB (at 20
o
C). The Combolook Color HD is capable of working with the return-path
signals in Cable-T 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 T pictures can be displayed with sound and attenuation inserted from 0-45dB to
determine picture quality with increased attenuation. T Channels can be saved as
favorites for easy tuning.
D B-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 car-
adaptor.
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 dBm 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.

This shows a typical constellation from a D B-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.

) 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 D B-S QPSK, D B-S2
QPSK and D B-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 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, 13/18 , and 22kHz state.
Digital Memory: There are 100 memory positions reserved for User data of Digital
frequencies. Each position stores the Name, frequency, 13/18 , 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, 13/18 , 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.

18
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.
