Anritsu Atomic Clock External Frequency Reference MA25401A

Anritsu Atomic Clock External Frequency Reference MA25401A

Description

For those needing enhanced frequency accuracy who cannot access a GPS signal, or where the regulatory authorities do not accept GPS as a frequency source for standards-based testing

  • Power consumption <200 mW
  • 10 MHz output for synchronization
  • USB interface for power
  • Short term stability (Allan Deviation) of 3.0e–10 @ t =1 sec

With an extremely low power consumption of <200 mW, the MA25401A brings the accuracy and stability of an atomic clock frequency reference to Anritsu’s handheld products. The MA25401A Atomic Clock Frequency Reference has short-term stability (Allan Deviation) of 3.0e–10 @ t = 1 sec, typical long-term aging of <9e–10 per month, and maximum frequency change of ±5e–10 over an operating temperature range of –10 °C to 55 °C. The MA25401A 10 MHz output may be used to synchronize the internal frequency reference to an external reference clock to within 5 ppb accuracy. A USB C interface is used for power.
