Can anyone help me out in finding how to calculate symbol rate from data rate in iDirect. Also can anyone share details on how to work with iNPT

Symbol rate= data rate/FEC rate/ modulation spectral efficiency


If your link is 2MB and using 3/4 TPC and QPSK modulation, your symbol rate will be

    symbol rate=2048/(3/4)/2= 1365.33 ksps

The bandwidth (kHz) required on satellite will be equal to the symbol rate times spacing (1.4 or 1.3)
