WebThe Pseudo Random Bit Sequence (PRBS) generator, NRZ pulse generators, and Mach-Zehnder modulators, are all located inside the Subsystem (see Figure 2). The use of a subsystem illustrates the hierarchy of the system, and simplifies the entire design process. Figure 2: Externally modulated subsystem WebA pseudorandom binary sequence (PRBS) is a deterministic and periodic sequence of length N that switches between two levels, say +a to another level, say –a [3]. PRBS is a very useful approximation to periodic white noise and it is widely used as forcing functions in statistically system testing. PRBS state can change only at discrete intervals

The R&S®RTP accomplishes this with hardware based clock data recovery (CDR) that supports a maximum nominal data rate of 8 Gbps or 16 Gbps, depending on the selected option. WebA PRBS is an algorithmically determined bit sequence that has the same statistical characteristics as a truly random sequence and simulates live traffic. A comprehensive test consists of applying PRBS to the facility. PRBS patterns stress the noise margin and the clock recovery.
