Overview
The Satlook HD is Satellite Test Equipment for the professional made in
Sweden. It can receive both DVB-S and DVB-S2 satellite signals and using an
advanced demodulator can “lock” on transponders using automatic modulation
type, symbol rate and FEC selection. It is easily operated with just three
controls and the basic functions are easy to learn.
The instrument is provided with a 3" LCD which is used to display information
such as signal strength, Spectrum, or Digital information.
The Satlook HD can be used to measure satellite signals from two LNBs at the
same time. Signal strength is presented graphically on the LCD display in form
of thermometer scales.
It can also sound a tone which increases with signal level on an internal
loudspeaker.
The Spectrum Mode 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 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.
The Satlook can store 100 positions of Satellite transponder information.
The instrument can easily scan through the memory positions and identify the
various Satellite transponders.
The polarisation of the LNB is switchable by setting the LNB voltage to 13V or
18V and the High Low band with a 22 kHz signal. The DiSEqC function
controls all DiSEqC accessories such as LNBs, switches, and positioners.
The instrument is supplied with a built-in and rechargeable battery and a
carrying case for protection of the instrument in the installation environment.

Power On
The Satlook HD is turned on by pressing and
holding the power on button for one second.
Power on tones indicate that firmware loading
has started. This takes about six seconds and
is shown by a progress bar on the display and
a pattern on the blue LEDs.
The Satlook HD initial mode can be set by the
user for convenience. Pressing and holding
the power button also turns off the Satlook
HD. The button must be held for more than
one second in order to turn the unit off. The Satlook HD also has an automatic
power down that is adjustable which will turn the unit off when there is no
activity. This can be set using the Setup Menu.
Navigation
The Menu Button and Menu Knob are the two controls used for navigation
through the menus and selection of functions. When the menu is off, pressing
the Menu Button shows the Menu. It is shown at the active mode, so if the
Satlook HD is in Digital mode, the menu is shown with the Digital entry at the
top.
Using the knob, the function that is to be executed is shown highlighted.
Pressing the Menu Button causes the function to be performed. For simple
functions such as switching the LNB Voltage with the 13V/18V function, the
Satlook HD performs this function, turns off the menu, and immediately returns
to the current mode.

For other functions, a new screen with choices is presented. Pressing the
Menu Button selects the highlighted item. Some of these other functions have
an exit function that is used to return to the current mode.
The Menu Knob is used for Frequency adjustment when in the Digital mode or
the Spectrum mode. When the Menu Knob is turned slowly, the frequency is
changed by 1MHz, but if rotated rapidly, the frequency step is increased
allowing for quick movement to the correct frequency.
Charging
Before using the Satlook HD, it should be fully charged.
To charge the Satlook HD, connect the external power supply or 12V Car
Cigarette Lighter Plug and then plug the external power supply into the DC
Input connector. The charging process will begin and the blue LED lights will
cycle indicating charging. The charging mode and time of charging are
displayed on the screen.
full charge can take up to 14 hours, but depending on the battery sate can be
competed earlier. When charging is complete, the bottom LED will be lit
indicating that the charging is complete. The Satlook HD can be operated using
the external power supply, but when the Satlook HD is on, no charging is being
performed.
The battery state is indicated on the nalog screen by a battery symbol.

EasyFind Mode
The EasyFind Mode is an easy way to point the dish at installation. When the
EasyFind Mode is entered, the Profile defined in the Setup EasyFind
Configuration is used. The five satellite transponders (or in the case of ll Sats,
all of the memory positions) which are in the Profile can be selected with the
knob.
Initially the display will appear as in the left diagram above and the RF signal
will be indicated on the display and by a tone with increasing frequency as the
RF signal increases. Turn the knob to select one of the five transponders in the
Profile. Point the dish in the approximate position, and move it slowly until the
Satellite is found as in the right picture above. There is an audible indication of
the correct satellite and a different audible indication if the wrong satellite is
found. If the indication is correct, then the screen will show the NIT data after a
few seconds for final confirmation. Now the Digital mode can be used for final
peaking. EasyFind Mode is exited by pressing the button.

Digital Mode
About Digital ode
When the user enters Digital Mode, the Satlook HD will attempt to receive a
DVB-S or DVB-S2 signal at the current frequency. The current frequency is
displayed in the centre of the screen and can be changed by the knob (within
the limits of the current LNB type and the 22 kHz setting).
When a signal is received, the Satlook HD is “locked” and the modulation mode
is displayed. This will be shown as QPSK, QPSK HD or 8PSK HD. The current
FEC and symbol rate are shown along with the LNB type definition being used.
If the signal is locked, then the frequency displayed includes the frequency
offset to the signal centre frequency. Usually, the Satlook HD will lock to a
signal up to 5MHz offset. When not locked, the frequency display contains no
offset and an utomatic Search is started in the direction given by the knob.
The Satlook HD checks the signal power at each 3 MHz interval and if the
signal is a peak, it will attempt to lock using the current Modulation settings
defined in the Setup/Modulations screen (DVB-S, DVB-S2, DVB-S Low Symbol
rate). The search will stop when a signal is locked. Turning the knob re-starts
the search in the direction of the knob turn. For Universal LNBs, if the
frequency reaches 11900 MHz in low band, the 22kHz signal will automatically
switch on and the search continues in high band. When searching down, when
the frequency reaches 11520 MHz in high band, the 22kHz will automatically
switch off and the search continues down.
The Search will end when a signal is locked or the frequency limits are reached.
Manual Tuning can be entered using the Digital Menu and is active until the
next press of the menu knob. To lock on signals when the signal symbol rate is
less than 15000 MSymbols/sec, the option “Low Symbol Rate” must be selected
in the Setup Modulations. For symbol rates below 7000 MSymbols/sec, the
signal identification may take several seconds.

constellation pattern is shown which is formed from a small subset of the IQ
decision points received by the demodulator. Occasionally, during an attempt to
lock, a calibration pattern can be observed momentarily. This is not a real
signal, but is an artefact of the demodulator process.
The current state of the 22 kHz signal and the LNB voltage are displayed at the
left. These are mirrored by the blue LED displays.
Once a transponder signal is locked, the Network Information is displayed at the
top of the screen. This can take some time to appear once the transponder is
locked. The transponder is supposed to send this data at least every 10
seconds, but sometimes there will be a transponder not sending any NIT data.
lso you should be aware that sometimes transponders send incorrect satellite
position data, because they are being used to repeat a transport stream used
on another satellite.
Visible Thermometer Bars
There are four thermometer bars displayed to indicate the state of the signal
being received. For all of these, the higher the thermometer bar, the better the
signal quality. Each of these thermometer bars has the recent maximum
displayed as a single bar. This maximum decays over time and so automatically
allows for peaking adjustments. The four thermometer bars are SIG, SNR, BER
and MER.
SIG
This is the power level of the signal at the current frequency. It is always
displayed whether the signal is locked or unlocked. This is not the same as the
display on the nalog screen.
SNR
This is the signal to noise ratio of the locked signal. This is a measure of the
meaningful power in the signal to the background noise of the signal. It is
shown in dB and is calculated by the demodulator using
SNR =
10log

(P

BER
This is the bit error ratio of the signal. The lower this value is, the better the
signal. It is shown in reverse on the thermometer bar for convenience so that a
maximum can be easily found. For DVB-S QPSK signals, this is BER =

).
For DVB-S2 QPSK or 8PSK signals, the BER is estimated from the ratio of Un-
correctable blocks to Correctable blocks.
MER
This is the modulation error ratio in dB. It is calculated from the constellation
pattern and represents how close the I and Q decision points are to the ideal
position. typical MER value is 16 dB. higher value is better and represents
a closer spread of IQ decision points. sample of 200 points is used for the
calculation.

Accessing the Digital enu
When in the Digital Mode, turning the knob will change the current frequency.
The Menu button will activate the Digital Menu.
Tuning
This function enters Digital Mode with the Search function disabled. Tuning can
be performed manually using the knob. Pressing the knob button enables the
utomatic Search mode.
Constellation
This function shows a larger version of the constellation presentation for a more
detailed view. The current frequency is displayed at the top and rotating the
knob will allow this to be changed. If locked, the current modulation is displayed
along with the BER, SNR, and MER thermometer bars. The current Bit Rate of
the transponder is shown.

X Polarity
This function can provide a visual reference of the signal level of the vertical
and horizontal polarisations at a frequency. This can be used to adjust the LNB
skew for maximum isolation. Many satellite transponders (like stra 28.2)
operate so that the vertical and horizontal polarisation signals are not usually at
the same frequency, but others (like Hotbird) have some transponders that
operate with vertical and horizontal polarisations at the same frequency. To
ensure that you use a “good” transponder for this isolation test, use the
Spectrum nalyzer to check the signals.
Transponder Chec
This function allows checking of all transponders for some satellites. The
satellites that are testable with this function are stra 28.2E, stra 23.5E, stra
19E, Hotbird 13E, Sirius 4.8E, and Thor 0.8W. When the function is started, the
satellite to be tested is shown on the screen. Turning the knob selects a
different satellite to be tested. Pressing the button starts the test. Each
transponder on the satellite is checked and if locked, then an upward vertical
line is shown. If the transponder is DVB-S2, then the vertical line is shown
slightly longer. If the transponder cannot be locked after three tries, then the
vertical line is downward. t the completion of the test, the knob can be used to
review any missing transponders and show the frequency and polarity for
further checking using the Spectrum or Digital modes. lthough all
transponders for a satellite are tested, failure to lock may occur for several
reasons. This is an accelerated test designed to run quickly and it is possible
that the demodulator may not lock in the short time allowed, or the transponder
may not have a broadcast “footprint” that covers your area.
