The MCR5000 Masterclock® Reference system is a 1U rackmount, precision time and frequency generator for a wide range of applications in the commercial, industrial, military and laboratory environment.

One compact unit can generate and read NTP, time code, and provides a 10 MHz sinewave all locked to the Atomic Clocks in the GPS satellites. Hold over accuracy and stability is maintained with a high stability oven controlled oscillator.

With specifications that are equal or better than almost any other similar product the MCR5000 is up to 60% less expensive than competitive units.

The MCR 5000 is available in multiple configurations to fit almost any need with configurable plug-in modules. Give our sales department a call and discover how easy it is to configure a system to fit your requirements.

  • Supports DHCP/BOOTP for automatic acquisition of network address, name servers, and time server configuration.
  • NTP synchronization options: server, port, timeout, query/listen mode.
  • Configuration of networking parameters, time zone/daylight savings time.
  • WinDiscovery provides automatic discovery of NTP clocks attached to network without changing PC's networking configuration.
  • Configuration is saved to non-volatile memory to survive power loss.
  • Encrypted messages prevent tampering with clock configuration.

Included With Every Configuration:

  • MCR5000
  • AC Power Cord
  • Cat-5 Ethernet Cable
  • Instruction manual and NTD Network Device Discovery Program, both on CD
