    Correct Answer
    A. 39.06dB
    Explanation
    Dropcable = 217/10=21.7
    21.7 multiplyed by frequency loss 1.8 = 39.06

    Rate this question:

  • 5. 

    Calculate the expected signal loss for the following: 
    • Dropcable = 165 meters
    • Frequency loss = 1.6 dB per 10 meters
     

    • 26.6dB

    • 24.5dB

    • 26.4dB

    • 29.1dB

    • 25.4dB

    Correct Answer
    A. 26.4dB
    Explanation
    Dropcable = 165/10=16.5
    16.5 multiplyed by frequency loss 1.6 = 26.4

    Rate this question:

  • 6. 

    Calculate the expected signal level at the ETB using the following information.
    • Signal level at tapbank output = 28dBmv
    • Dropcable length = 180 meters
    • Frequencey loss = 1.9dB per 10meters

    • -6.2dBmv

    • -2.8dBmv

    • -5.7dBmv

    • -7.2dBmv

    • -8.6dBmv

    Correct Answer
    A. -6.2dBmv
    Explanation
    Dropcable = 180/10= 18
    18 multiplyed by frequency loss 1.9 = 34.2
    Tap output = 28
    28 minus 34.2 = -6.2

    Rate this question:

  • 7. 

    Calculate the expected signal level at the ETB using the following information.
    • Signal level at tapbank output = 19dBmv
    • Dropcable length = 138 meters
    • Frequencey loss = 1.5dB per 10meters

    • -3.8dBmv

    • -1.7dBmv

    • -0.9dBmv

    • -1.87dBmv

    • -2.7dBmv

    Correct Answer
    A. -1.7dBmv
    Explanation
    Dropcable = 138/10= 13.8
    13.8 multiplyed by frequency loss 1.5 = 20.7
    Tap output = 19
    19 minus 20.7= -1.7

    Rate this question:

  • 8. 

    Calculate the expected signal level at the ETB using the following information.
    • Signal level at tapbank output = 17dBmv
    • Dropcable length = 60 meters
    • Frequencey loss = 1.3dB per 10meters

    • +9.2dBmv

    • +13dBmv

    • +10.2dBmv

    • +8.6dBmv

    • +12.2dBmv

    Correct Answer
    A. +9.2dBmv
    Explanation
    Dropcable = 60/10=6
    6 multiplyed by frequency loss 1.3 = 7.8
    Tap output = 17
    17 minus 7.8 = 9.2
