Specifications are subject to change without prior notice
*1 Initial frequency tolerance: At delivery
Initial frequency tolerance is defined as frequency drift within 1 year after the final adjustment
*2 Time to valid output signal:
Valid output signal is determined at the point where the Bit Error Rate meter starts detecting a 4800bps,
1010.. repeated signal.
The valid output signal varies with the temperature conditions. You must conduct field testing to verify the
waiting time for a valid output signal in the user system.
