    Product Description

    The Pseudo-Random Binary Sequence (PRBS) Generator designed to be used with the Bit Error Rate Indicator, Model 9423 (not included), to measure the reliability (error rate) of different digital transmission systems.

    Using an external clock, the PRBS Generator produces a pseudo-random sequence of bits. The bit rate can be varied from 100 bps to 5.44 Mbps. The length of the pseudo-random sequence of bits is selected through a switch and is indicated on the front panel of the module. Sixteen sequence lengths are available between 1 and 65,535 bits. One of the sequences is 511 bits long, thus meeting with recommendation V.52 of the CCITT. The generated pseudo-random bit sequence recurs indefinitely. The generator produces a synchronization signal for oscilloscope observation of the PRBS.

    A delayed PRBS is required when assessing the reliability of a digital transmission system. The delay of the PRBS must match that caused by the digital transmission system under test. For this purpose, the PRBS can be
    delayed by a fraction of a bit (fraction of a clock period) or by a whole number of bits (whole clock periods) using controls located in the DELAY block of the module.
