(option r&s® smiqb20 required)
the option r&s® smiqb21 allows the signal decoded by the dut to be assessed. to do so, the waveform memory is filled with a prbs-modulated (pseudo random binary sequence) data sequence. the data is decoded by the dut and forwarded to the r&s® smiq as clock and data signals. r&s® smiq synchronizes to the known prbs sequence and counts the bit errors.
