Page 3: Description
Menus/help-displays are shown on the LCD-screen (64x128) beside the monitor. Both analog SAT-TV and CATV channels can be tuned in and viewed upon. The COMBOLOOK is able to work with the return-path signals in Cable-TV networks (5-65 MHz) according to the EN50083 standard. -

6. Adapter BNC-male/F-female. The instrument’s keypad, control knobs and control-button are shown on the picture below, these items control the COMBOLOOK’s functions and modes. The power-plug is used when charging the battery or running the instrument with the COMBOLOOK power supply. -
Page 5: Connection
Use the main switch to turn the instrument On and connect a signal-source to one of the two inputs (SAT-TV) via the BNC/ F-connector adapter. After a few seconds to warm-up the COMBOLOOK will ask You to select what part of the instrument You will work with (TV or SAT ). -

1. Picture. After choosing a specific frequency; access the TV-mode by pressing button # 1 or “Picture” in the Main Menu. The tuning knob controls the frequency-position in this mode but the function changes when the control button is pushed. The chosen function is displayed at the top of the LCD display;... -

22 kHz on/off. Selected position is displayed at the top of the LCD-display. 2. Digital COMBOLOOK can easily and very accurate measure at digital transponders (MPEG- streams). This kind of measuring is very good to do when an installation is done, to control and verify that the installation is correct performed (fingerprint of the installation). - Page 8 * Test the maximum with the X-pol function (button nr 4 in the main menu). The instrument will measure the strength of the selected peak and then automatically "jump" to the other polarisation and measure there as well (same frequency and settings).
- Page 9 Corrected Bits –Bits that have been corrected in Viterbi. Should be as low as possible. UCB: Uncorrected Blocks – Blocks unable to be repaired. Value should be zero. Very small numbers of uncorrected block will result in loss of picture (mosaic).

Enter the Memory function (button nr 3) and push Save button nr 1). The instrument asks: -”SAVE. ARE YOU SURE ?” Check that the Memory position is the right one (displayed at the right bottom on the monitor).

The instrument will measure the strength of the selected peak and then automatically "jump" to the other polarisation and measure there as well (same frequency and settings). The difference (for ex. -7dB) is presented on the right hand side of the display. - Page 13 Measured data can be stored. Read more about the Memory-function under section 4 below. 2. Reference cursor and signal to noise ratio. COMBOLOOK has the capability to perform measuring of the signal/noise alt. Picture-carrier/audio-carrier ratio. The function is relatively difficult to implement fully automatic and a more simple, manual, tool is used in this instrument.

Multichannel Channels (frequencies) that have been memorized under Main menu section 1 and 2 are displayed and measured at, together here. Up to 10 channels can be measured at simultaneous. Notice that all the channels can have individual setup of 13/18V resp. - Page 15 9. Memory Storing spectrum-pictures. All spectrum-pictures can be stored in the COMBOLOOK. This is very useful for documentation and to use later on for recognizing/identifying of that satellites characteristic spectrum The Mix-function helps to identify and “find the way back” to already known (and previously stored) satellites.

These working-areas might differ a lot depending on where the instruments are being used (geographically) or by whom. For that reason the COMBOLOOK has the unique possibility to do a individual setup of such frequency-bands. Programming the frequency-bands, do like this: * Chose a frequency-band to programme (for ex. -
Page 25: Set (Personal Setup)
* Chose any of the previous (see above) programmed frequency-bands in the list. L. Set (personal setup). The COMBOLOOK-instrument can be setup for a better individual performance and to do special kind of measuring. These kind of setups are done under the menu nr 6 (SET) in the main-menu. -
Page 26: Maintenance
Remember that a cold battery has much lower capacity than a warm one. COMBOLOOK is designed for outside use in rough conditions but it should not be exposed for rain or snow as this can damage or shorten the lifetime of the instrument. -

When the battery has been recharged, COMBOLOOK is ready to be used. PC-software. With this COMBOLOOK comes a PC-software (on CD) which makes it easy to transfer the earlier saved memory-positions from TV LOOK to a PC. The software makes it also simple to transfer the data to other software’s (like word- processing programmes) and add on information (like addresses, time-date etc.). - Page 28 Picture-screen: 4.5”-monitor, B/W Menus: On LCD 64x128. Memory: Lots of spectrum pictures can be stored with name. Stored spectrum can be mixed for easy identification of satellite. -“Maxhold”-function. Favorite channels Both analog and digital frequencies can be stored (with name). PC-connection: RS232-output and PC-software.
