Containing an ovenized quartz crystal time-base, the 2960AX disciplined quartz frequency standard is stable to better than ±5 x 10-11 per day when disciplined to a 1-pps source via a GPS smart antenna ...

In addition to 10- and 5-MHz front- panel outputs, the 2975AX disciplined quartz frequency standard features a synthesized output that can be set in 1-μHz steps up to 20 MHz. The value of the ...

Accurate timing is one of the most basic requirements for so much of the technology we take for granted, yet how many of us pause to consider the component that ...

NIST scientists have published results establishing a new atomic clock, NIST-F4, as one of the world’s most accurate timekeepers, priming the clock to be recognized as a primary frequency standard — ...
