    24 Chapter 06 – Measuring range Note: The internal error protection is called LDPC (Low Density Parity Check) in the DVB-S2 standard, and the external error protection is called BCH (Bose Chaudhuri Hocquenghem). In particular, the performance of the LDPC error protection is significantly better than that of the inner error protection of DVB-S (Viterbi). 6.3.6 MER measurement The MER value of the signal in the baseband (after the demodulator) is displayed in dB in the MER window.

    Chapter 06 – Measuring range 31 Here you can set the UB centre frequency that corresponds to the selected SCR address. This is the frequency that a connected receiver needs to tune to. Use the Up and Down keys, the ← and → keys, or the numeric keypad to set the UB centre frequencies within the range from 950 MHz to 2,150 MHz.
  • Page 34 32 Chapter 06 – Measuring range The measuring receiver is tuned as described in “Frequency input”. The difference when using the UNICABLE control is that the desired transponder frequency is converted to the centre frequency of a UB slot in the UNICABLE unit. This means that the measuring receiver must send the transponder frequency to the UNICABLE unit as a UNICABLE command and then tune itself to the correct UB slot centre frequency.
