Remote Commands

byte_sync [n] (Analyzer only)

Byte Synchronization. This command sets the long-word pattern synchronization threshold. This threshold does not apply to short-word patterns, or PRBS patterns. The long-word synchronization threshold is set in terms of an integer, n, which corresponds to a BER threshold. In the table below, the ratios of errors to bits corrrespond to the window examined and the maximum errors for the threshold.
