Abstract :
This instrument will generate upon command any one of three serial code sequences in a binary coded decimal (BCD) format representing either 1) time of day, 2) time and date, or 3) event number. Either a single code sequence or continuously repeating sequences can be generated. The instrument is intended to be used in a biomedical data acquisition system to permanently identify, index, and synchronize analog or digital data recorded on magnetic tape or oscillographic paper. Three-digit event codes, consecutively numbered 1 through 999 in successive frames, are particularly valuable for indexing experimental maneuvers or deliberate changes in experimental variables. Individual digits in the code format are easier to interpret visually than are corresponding digits in recognized time code formats.
