4065C

Primary Frequency & Time Standard

Get A Quote
Symmetricom's 4065C™ is a high performance cesium frequency and time standard that provides the ultimate in accuracy and stability. An exceptional frequency distribution capability, the 4065C includes nine RF, high isolation, low phase noise outputs and one programmable TTL output. The nine RF outputs come in three different frequency values of three each or may be customized to meet individual frequency requirements. The newest cesium beam technology featured in this generation of the 4065 delivers improved efficiency, better performance, longer life, a lower cost of ownership and ease of use. Simply connect to a power source (AC or DC) and the instrument automatically powers up to its full accuracy specifications within thirty minutes or less.

The 4065C produces accurate, stable, and spectrally pure sinusoidal signals. To accomplish this, a cesium beam tube resonator stabilizes the output of the instrument’s ovenized quartz crystal oscillator. This oscillator drives output signals at 1, 5, and 10 MHz. The instrument also features precise time-of-day/day-ofyear with 1 PPS outputs. Optional telecommunication outputs are available for T1 and E1, framed and clock signals. The instrument meets stringent precision time and frequency control requirements demanded of:

  • Reference sources for synchronization of satellite ground terminals and
         remote stations
  • Shipboard, aircraft, and land-mobile systems for navigation, timing, and
         communications
  • Primary reference sources for positioning in oil exploration and mapping
         environments
  • Independent time and frequency reference for uninterrupted service
  • Master frequency and timing references for secure high data rate
         communication systems
  • Master frequency and timing references for TV applications including
         Color Burst systems and HDTV Broadcast
  • Master frequency and timing references in laboratory research facilities
  • Primary reference instruments in metrology facilities
  • Telecommunications master clock systems that meet Stratum 1 primary
          reference source needs for digital communications systems, in both
          public and private telephone networks
