An analysis is made of synchronization properties of patterns suitable for incorporation in the 240 bit standard IRIG 102-64 word format. Sequences of length m 7, 13 and 17 bits are used as prefix of an 240-m bit randomly generated word. An analysis which includes a digital simulation is made to determine the synchronization capabilities of each of those sequences. In the first part of the study, for a randomly generated 240 bit word, the average number of false sync sequences generated and the probability of obtaining at least one false sync were computed for each prefix and confirmed by simulation tests. The sync sequences were then appended to the 240-m bit word and the sync process was defined. The process was simulated for each prefix to determine the number of words lost before acquiring sync and the number of false syncs.
