BER test set does two tasks: Calculating BER and generating pseudo random bit sequence. In order to do the second task, the bit rate must be defined in the component itself (as in PRBS generator component). So the bit rate determined in the component itself is the bit rate it uses to generate the bit sequence.
Nonetheless, for OFDM systems there is a box stating “using OFDM” which can be checked. If it is checked and all the corresponding OFDM characteristics are defined according to OFDM components, the the bit rate (which Gokul has asked about) is calculated in the following way:
overall bit rate = bit rate defined in BER Test Set * (Maximum possible subcarriers / number of subcarriers in port)
So in Gokul’s example, the bit rate is 10e9 using the above formula. We could have easily not used script mode to refer to laouy parameters bit rate, so it doesn’t necessarily have anything to do with the layout parameters bit rate.
