    Default Am primit prin email

    Am trimis si lui Fanta dar vad ca nu doreste sau nu-l intereseaza sa ataseze documentul.

    Editat!
    va rog sa nu postati astfel de documente.
    nu trebuie sa creem astfel de probleme probleme unui DTH ce inca nu a aparut pe piata.

    Multumesc,
    Fanta


    Din cate vad se preconizeaza 25.000 de instalari pe luna ceea ce mi se pare extrem de mult.
    Stie cineva mai multe?

    Daca erai mai atent, de ei intrebam intr-un alt topic, si afacerea asta se pare ca e fumata, e al lui vantu si era valabila inainte de licitatie...

    Amuzant : GMG Media Box se asteapta la un numar mare de clienti incepind cu prima luna de lansare a serviciilor.

    Cred ca astia sunt mai aerieni decat cei de la boom , chiar daca sunt in mare aceiasi angajati .

    Ai cam ghicit... sunt emigrantii de la BOOM o mare parte din ei... sunt optimisti, ce sa-i faci?

    Probabil erau optimisti inainte de 31.03.08 ....

    se pare ca Boom nu a pierdut ci s-a scapat de niste angajati... )
    ar trebui sa-i bombardam cu oferte sa vedem ce raspund...

    asa e, de cand noii manageri si-au ocupat posturile, situatia a inceput sa intre la ei in normalitate. mi-au zis si alti prieteni care colaboreaza cu boom ca au fost cautati de noii manageri, le-au fost cerute scuze pentru incidentele pricinuite de vechii sefi de departamente care au plecat apoi la vantu dth si le-au fost facute intr-un timp scurt platile restante. acum sa se mai rezolve si problemele cu hat si cu asta basta. de cand au inceput problemele cu platile, de anul trecut din primavara, se aude ca peste 800 000 colaboratori din toata tara i-au parasit. acum, noua conducere incearca sa le recastige increderea si sa colaboreze in continuare.

    Default Copy/Paste

    Asa arata documentele originale de la Boom din care au facut astia copy/paste. Cata nesimtire. Macar puteau traduce specificatiile in romaneste.... La Boom erau in engleza ca nu intelegeau sefii romaneste dar aici? Ce teapa si-a luat Vantu' cu amatorii de la Boom. Bine macar ca nu-i mai plateste pentru mult timp.

    Imi pare rau ca nu se poate atasa documentul original de la Boom ca are si antet si arata alfel.

    Ce penibil.

    Acceptance Test Procedure

    1. Gain
    1.1. General
    1.1.1. The test method is based on a comparison between the measured level (w/ spectrum analyzer) of a stable carrier on the satellite to the measured value using a reference reflector.
    1.1.2. The test should be performed under “Clear –Sky” conditions

    1.2. Test Equipment
    1.2.1. Spectrum Analyzer.
    1.2.2. Reference LNB
    1.2.3. Line Amplifier (if necessary).
    1.3. Test Set-Up
    (*) Device Under Test


    1.4. Test Procedure
    1.4.1. Connect the LNB + coax cable to the SA and measure the level of the reference carrier.
    Use one of the satellite’s beacons .
    1.4.2. Make sure the carrier is stable, measure the pick value of the carrier ( use the Max . Hold function of the SA).
    1.4.3. Remove LNB + cable from reference antenna, install on the tested reflector and measure the level.
    1.4.4. It is recommended to use the beacon carriers of Amos1/2 satellites as a reference for the measurement. The beacon carriers are circularly polarized.
    • The following are the carriers’ parameters :
    • Amos1 ( Low frequency beacon) …………..10,951.000MHz
    • Amos1 ( High frequency beacon)…………...11,451.000MHz
    • Amos2 ( low frequency beacon)………….…10,949.000MHz
    • Amos2 ( High frequency beacon)…………...11,200.000MHz
    Recommended spectrum analyzer test conditions :
    • RBW = 1KHz
    • SPAN=200KHz
    • VBW=30Hz
    • Max Hold (to compensate the carrier fluctuations).
    1.5. Test Results
    The levels’ difference is the gain difference between the reference reflector and the tested one. .

    Incoming Inspection.

    Acceptance Test Procedure

    1. Noise Temperature
    1.1. General
    1.1.1. The test objective is an indirect measurement of the LNBF’s Noise Temperature.
    1.1.2. The test method is based on a comparison between the measured C/N (w/ spectrum analyzer) of a stable carrier on the satellite to the measured value using a reference LNB.
    1.1.3. The test should be performed under “Clear –Sky” conditions

    1.2. Test Equipment
    1.2.1. Spectrum Analyzer.
    1.2.2. Line Amplifier (if necessary).

    1.3. Test Set-Up
    (*) Device Under Test

    1.4. Test Procedure
    1.4.1. The reflector used for the test should be with good performance.
    1.4.2. It is highly recommended to use a 100cm reflector antenna.
    1.4.3. The reference LNBF should be with calibrated performance.
    1.4.4. It is recommended to use the beacon carriers of Amos1/2 satellites as a reference for the measurement. The beacon carriers are circularly polarized.
    • The following are the carriers’ parameters :
    • Amos1 ( Low frequency beacon) …………..10,951.000MHz
    • Amos1 ( High frequency beacon)…………...11,451.000MHz
    • Amos2 ( low frequency beacon)………….…10,949.000MHz
    • Amos2 ( High frequency beacon)…………...11,200.000MHz
    Recommended spectrum analyzer test conditions :
    • RBW = 1KHz
    • SPAN=200KHz
    • VBW=30Hz
    • Max Hold (to compensate the carrier fluctuations).

    1.4.5. The measured noise floor should be at least 15 dB above the spectrum analyzer’s floor. In case the difference is less than 15dB a correction factor should be added to the measured values (see table bellow).
    1.4.6. The same spectrum analyzer’s configuration should be used for each and every tested LNBF.
    1.4.7. It is important to make sure the antenna alignment is the same for each and every tested LNBF.
    1.4.8. The Noise Figure of the tested LNBF is the difference between the C/N measurements.

    Correction factors for C/N measurements :
    Measured Noise
    Above
    SA Noise Floor
    [dB] Correction

    (dB)
    16 -0.1
    15 -0.15
    14 -0.18
    13 -0.22
    12 -0.28
    11 -0.36
    10 -0.46
    9 -0.48
    8 -0.75
    7 -1


    2. Gain and Frequency Stability
    2.1. General
    2.1.1. The test objective is to verify the frequency and gain stabilty of the LNBF.
    2.1.2. The test method is based on monitoring the level and frequency of a stable CW carrier for at least 12 hours.
    2.1.3. The test should be performed under “Clear –Sky” conditions
    2.2. Test Equipment
    2.2.1. Spectrum Analyzer.
    2.2.2. Line Amplifier (if necessary).
    2.3. Test set-up ( as in 1.3 above)
    2.4. Test Procedure
    2.4.1. Use a 100cm antenna
    2.4.2. The reference carrier should be a stable one transmitted from the satellite such as one of the beacon carriers (see details above 1.4.4) . The received C/N should be >15dB ( @BW=100KHz)
    2.4.3. Recommended spectrum analyzer set-up:
    • RBW=100KHz
    • SPAN=500KHz
    • VBW=1KHz
    2.4.4. Monitoring the frequency and level can be done by the following options:
    • Using the Min/Max Hold function of the spectrum analyzer.
    • Manual monitoring of the level and frequency
    • Automatic PC software which can monitor and control the spectrum analyzer.
    2.4.5. The results should be presented on a 12 hours graph.
    2.4.6. The maximum level and frequency changes should be indicated as Peak to Peak values.
