1. Description:

The Emitor STARLOOK- D is a Swedish designed Spectrum-analyzer and SAT-TV instrument.

STARLOOK- D is made for exact alignment and adjustment of satellite-dishes.

The instrumentet is intended for professional use when high accuracy and precise information is needed.

It´s easily operated as it uses new very powerful processor technology -not a lot of unnecessary buttons and knobs.

The basic functions are easy to get a hold on and takes only minutes to learn.

The instrument is provided with a 4.5" B/W-monitor which either shows normal SAT-TV-channel, the frequency

spectrum 950-2150 MHz (or parts thereof) alt. Digital data.

Menus/help-displays are shown on the LCD-screen (64x128) beside the monitor.

Analog SAT-TV channels can be tuned in and viewed upon (Multistandard Video –PAL, NTSC and SECAM).

Audiofrequencies between 5.5 – 8.5 MHz can be listened to.

The spectrumfunction shows the frequencyband 920-2150 MHz and satellite-signals are easily discovered .

The spectrum can be expanded (zoom in) for correct adjustment of the polarisation (“cross-polarisation”).

The instrument has very high resolution and accuracy. It presents measured data +2 dB (at around 20 C).

Tuning of the frequency is done with the main knob in 1 MHz step and the tuned in frequency is displayed either

on the monitor or on the LCD.

STARLOOK- D presents, under one of the sub menus, digital information like BER (bit error rate),

constellation-diagram (QPSK) and S/N (signal/noise ratio).

Switching between TV-mode, Spectrum-mode, Digital-mode are easily done by pushing a button on the side

of the instrument.

STARLOOK- D can handle a lot of memory-positions and both spectrum-pictures and certain frequencies can be

saved (both analog and digital transponders).

Saved spectrum –positions can be mixed with an actual reading for easy satellite-identification och control of

signal-levels.

Measuring on a group of channels can also be done with up to 10 frequencies at the same time.

These can be individually programmed with 13V or 18V, 22 kHz on or off.

The polarisation of the LNB is switchable 13V/18V and the Hi-Lo band with 22 kHz-tone.

Both functions are indicated on top of the LCD.

The instrument is protected from short-circuit when connecting the LNB.

The DiSEqC-function controls all DiSEqC-accessories (like switches and LNB´s). The function is easily

implemented and very flexible to use.

Notice that the STARLOOK- D also can run DiSEqC-actuators. It can be setup for running DiSEqC 1.2 (normal

DiSEqC-actuators), SatScan (Nokia) and SatSelect (Triax).

The power of the instrument is supplied by a built in and rechargeable battery.

The battery is recharged from the external battery charger or the car-adaptor.

Battery-status is shown on top of the LCD-display (in shape of a battery).

Even though the instrument has a lot of functions it is still very light and flexible.

STARLOOK Mark III DiSEqC weights only about 4 kg incl. the battery and the carrying-case.

The control-button handle a few important functions (Should be controlled by this button). It

is important to learn how to use the control-button in order to handle the STARLOOK- D

easy and correct.

The functions of the control-button in the different modes.

Spectrum: Picture-mode: Digital-mode:

Frequency Frequency Frequency

Bandwidth(span) Memory Memory

When the STARLOOK- D is in Frequency-mode, the cursor is controlled by the knob.

Try to move the cursor up/down by turning the knob left/right.

D. Information:

The cursors position (frequency), the spectrums startfrequency (920 MHz), the spectrums

stopfrequency (2150 MHz) and bandwidth (1231 MHz) can be read out on the picture-

screen.

The most important measured data , the dB-value, is shown in the middle of the monitor.

Measuring of the tuned in frequency is done continuos and the presentation is being

updated a couple of times per second.

III. Functions MAINMENU

The instrument starts with the MAINMENU where the following functions can be choosed:

1. Picture TV-mode.

After choosen a certain frequency it´s easy to access the TV-mode by pressing button nr 1

“picture” in the Mainemnu.

- The knob controls the frequency-position in this mode but the function change when the

control-button is pushed (the function choosed is displayed on top of the LCD).

The function switch between Frequency and Memory.

Measuring on a certain frequency can be done in this ”Picture”-mode (dB-value is shown

in the LCD-display).

(5).

Other functions in the Picture-mode:

1. Invert Switch between normal video (KU-band) and inverterad

Video (C-band). Selected position is displayed in the LCD-display.

2. Sound For listening to analog audio. Audio volume and frequency

(5.5 – 8.5 MHz) are adjusted with the two small knobs just under the

main-knob.

3. Memory For storing the different analog and digital channels (frequencies).

Tune in the ”right” frequency before entering this function

(ex. 1720 MHz).

Enter the Memory function (button nr 3) and push Save (button nr 1).

The instrumentet asks: -”SAVE. ARE YOU SURE ?”

Check that the Memoryposition is the right one (displayed at the right

bottom on the LCD-display). If not, chose a new one with the

knob (0-99). Free positions are named: Pos free

After selecting a position, push button nr 1 (YES).

Notice that even the preselected 13V/18V, 22 kHz on/off will be

memorized.

Text-editor:

When the channel (frequency) is saved, the Text-editor appears on the

monitor which makes it possible to enter a name for that memory-

position (ex. CNN).

Use the knob to select the first letter (ex. C) and save it with the control-

button. Move to the next letter (ex. N) and so on.

If a mistake is made and wrong letter is saved, simply correct by

pushing button nr 1 (Delete) and the cursor will jump one position

backward.

4. Atten: Attenuation. Manuell attenuation 15dB on/off.

Selected position is displayed in the LCD-display.

0. 13/18V Selection of 13V alt. 18V. Chosed position is displayed at the top of the

LCD-display.

#. 22kHz 22 kHz on/off. Chosed position is displayed at the top of the LCD-

display.

2. Digital

STARLOOK- D can easily and very accurate measure at digital transponders (MPEG-

streams).

This kind of measuring is very good to do when an installtion is done, to control and verify that

the installaion is correct performed (fingerprint of the installation).

It is less accurate when trying to find a satellite and adjusting the cross-polarisation.

Therefore, start with finding the ”right” satellite with the spectrum-function. Check and adjust

the cross-polarisation with the “Max zoom in” function.

Chose a suitable transponder (put the cursor on top of a ”peak”) and select function 2 in the

Mainmenu (Digital).

The monitor displays, in the left upper corner, the so called, constellationsdiagramme (QPSK).

To the right of it, 4 ”lock-parameters” and a time counter (that shows the “lock-time” on a bit-

stream”) are shown.

The other measured data like the S/N-ratio (signal/noise ratio) och BER (bit error rate) are

displayed just under the constellationdiagram in the shape of Bar-graph´s (thermometer-scales).

A locked frequency can look like this.

Notice:

• The constellationdiagramme is like ”a shower of hail”. No signal will spread out the

noise over the window. The better signal the more concentrated ”hailstorm”.

• SNR. The signal/noise ratio should be as high as possible. A good signal should have at

least 8.0 dB S/N-ratio.

• BER. The Bit Error Rate should be as low as possible.

As the values are really small, on the other side of zero (presented as something raised to

minus something), they should be as high as possible.

A BER at 5.00 –05 is therefore better than 9.00 –04.

A BER at 4.00 –05 is therefore better than 5.00 –05.

It can be said, in general, that a signal should be at least x.xx –04 to be accepted.

Other Digital functions:

1. Search + Automatically search for the next digital transponder higher in

frequency. Searching is displayed at the bottom of the monitor.

2. Search – Automatically search for the next digital transponder lower in

frequency. Searching is displayed at the bottom of the monitor.

3. Memory For storing digital transponders (digital channels - frequencies).

Tune in the ”right” frequency before entering this function

(ex. 1650 MHz).

Enter the Memory function (button nr 3) and push Save (button nr 1).

The instrumentet asks: -”SAVE. ARE YOU SURE ?”

Check that the Memoryposition is the right one (displayed at the right

bottom on the monitor). If not, chose a new one with the

knob (0-99). Free positions are named: Pos free

After selecting a position, push button nr 1 (YES).

Notice that even the preselected 13V/18V, 22 kHz on/off will be

memorized.

- Load a memory-position by pushing the control-button –“Memory”

will appear on top of the LCD and a memory-position will be

shown in the bottom of the LCD-display.

Step between the stored memory-positions with the knob.

Text-editor:

When the channel (frequency) is saved, the Text-editor appears on the

monitor which makes it possible to enter a name for that memory-

position (ex. Digital).

Use the knob to select the first letter (ex. D) and save it with the control-

button. Move to the next letter (ex. i) and so on.

If a mistake is made and wrong letter is saved, simply correct by

pushing button nr 1 (Delete) and the cursor will jump one position

backward.

4. DiSEqC Chose between the different DiSEqC commands by using the buttons

on the side of the instrument.

Submenu 7 (SWx) shows the extended DiSEqC-commands

(DiSEqC 1.1).

Submenu 8 (Motor) shows the command-list for DiSEqC actuator-

control (DiSEqC 1.2).

Even 13/18V and 22 kHz can be adjusted under the DiSEqC-menu.

0. 13/18V Selection of 13V alt. 18V. Chosed position is displayed at the top of the

LCD-display.

#. 22kHz 22 kHz on/off. Chosed position is displayed at the

top of the LCD-display.

3. Full spectrum - ”Max zoom in” - Span Min /Span Max.

This function makes it easy to ”jump” between full spectrum (920-2150 MHz) to

”Max zoom in” (250 MHz bandwidth).

The ”Max zoom in”-function is very good to use when adjusting the cross-polarisation.

• Move the cursor to any desired frequency (peak).

Push the nr 3 button (span Min) on the keyboard.

The instrument will ”zoom in” max. at that selected frequency (250 MHz bandwidth).

Rotate the LNB so that either the Horisontal or Vertical polarisation will be in its max-

position –adjusting the cross-polarisation.

Pressing the nr 3 button again (span Max), gets You back to ”Max zoom out”.

4. Atten Attenuation 15dB. Manuell on/off with button nr 4.

Selected position is displayed at the right hand side of the monitor.

5. DiSEqC Chose DiSEqC command by using the keyboard on the side of the

instrument.

Submenu 7 (SWx) shows the extended DiSEqC 1.1 commands.

Submenu 8 (Motor) shows the DiSEqC actuator-control commands (DiSEqC 1.2).

Even 13/18V and 22 kHz on/off can be adjusted in this mode.

6. Setup Basic-operation setup:

1. LNB L.O. Select the LNBs L.O. for showing the correct LNB frequency.

Default setting is button nr 9 (IF).

2. Digital. Select the satellite-type. Europe uses DVB (DBS).

USA and Japan uses DSS.

(9)

3. Analog. Chose between KU-band and C-band (normal or inverted video).

4. Motor. Chose the type of actuator to be used; standard DiSEqC 1.2,

SatSelect or SATSCAN.

5. Display. submenu units: Select dB-presentation: dbuV,

Dbm or dBmV.

Under submenu LCD can contrast (level) and Backlite (on/off) be set.

6. AutoOff. Chose between some automatic turn-off alternatives (timer).

7. Version. Tells about the units serie-nr and manufactured date.

7. Beeper It might be tricky to install a Sat-dish and, at the same time, try to watch the

signal-level on the instrument.

Therefore the instrument has a very useful ”beeper”-function to help finding the

max-strength signal. It works with a pitch tone that gets higher and higher the

better the signal gets.

The beeper is turned on and off with button nr 7.

Notice that the function works with a narrow bandwith (one transponder) and

not with the full bandwidth.

To use the function: put the cursor on top of a selected ”peak” and align the dish.

8. Spec Special-functions. Select with button nr 8 in the Mainmenu.

1. Max hold

Max hold is a very good function for, over a longer time period, watch a certain

frequency-range. This to see how/if temporary signals/disturbances can affect the

picture quality.

Adjust the frequency-bandwidth (see Function 3) and put the cursor on the

frequency (peak) to watch. Chose with button nr 1 the ”Max hold”-function. The

instrument starts to sample all top-values in the shown bandwidth and only

updates the presentation if there´s any new measured data with higher dB-values

than the previous measured.

Turn off the function by pressing the button nr 1 again (No hold).

Measured data can be stored. Read more about the Memory-function under section

4 below.
