DESCRIPTION
The 6047 IRIG Time Code Reader provides precision time references for measurement data acquired by the 6000 data
acquisition system. Time is acquired from time code signals, typically IRIG B, applied to the BNC input. Time
data is captured by the 6000's sample clock and can be selectively output in the multiplexed data stream with
measurement data at any available sample rate. It enables data processing or export software. The 6047 occupies
one slot in a 6000 series mainframe or slave enclosure.
The IRIG Time Code Reader derives a 1 MHz clock from the IRIG signal that is accumulated to provide current time
with 1 micro-second resolution. Current time is loaded into binary and BCD output registers (days, minutes,
seconds, milliseconds and microseconds) by the 6000's sample rate clock assuring that the time recorded matches
data sampled by all series 6000 input and output cards.
A stabilized oscillator is disciplined to the IRIG time source. If the time source is lost, the time reader
continues to maintain and output time, however time accuracy will be degraded as the time error introduced by the
oscillator increases.Using the 6000 digital I/O cards provides a means of recording the time of event inputs or
the time an event is output.
