Product Information


Configurable and Scalable

The 4380A is packaged in a 1U rack-mountable unit supporting hot-swappable input/output cards that provide configurability and scalability. The cards can be operated in any of the six card slots located at the rear panel of the unit, and the unit will automatically detect and configure the system based on the card(s) installed.

Standard input/output card options for the 4380A include:

  • 4394A Pulse Output
  • 4395B-10 (10 MHz)
  • 4395B-5 (5 MHz)
  • 4395-1 (1 MHz)
  • 4387A, 4387A-6V, 4387A-1V (Modulated IRIG/NASA36)
  • 4393A Time Interval Counter (TIC)

Additional input/output cards are available upon request for specialty applications. The unit also has the capability to incorporate an ultra high stability external atomic oscillator, e.g., Microsemi’s 5071A Cesium beam tube and/or MHM 2010 Active Hydrogen Maser, when available. This capability further enhances the performance of the unit without requiring additional upgrades. The external frequency reference may be monitored by the 4380A via RS232 through either of the USB connectors on the rear of the unit using an adapter cable. External references can extend the time of operation without being impacted by a GPS outage to days or even months.
