Abstract : The patent relates to satellite relay communication systems. Apparatus is described for automatically measuring and indicating in real time, the absolute bit error rate introduced in a transmitted bit stream by the data link. In an exclusive test mode, a selectively predetermined random or fixed code sequence is transmitted over the link. At a receiver site, the identical, reference code sequence is generated for comparison, on a bit-by-bit basis, with the transmitted sequence after bit and code synchronization are completed.
