Download Data Sheet (79 KB)

The frequency standards from Pendulum suit the highest demands for stability. All frequency standards offer multiple buffered outputs (5x or 10x outputs of 10 MHz sine). Choose from the low-cost 6688 based on a very-high-stability oven-controlled SC-cut crystal oscillator or the 6689 with a built-in Rubidium atomic clock. These standards are suited for use in automatic test systems, for example in the production department of telecommunications

  • Rubidium or high stability oven frequency reference standard
  • Distribution amplifiers for 5x10 MHz and 1x5 MHz outputs as standard
  • Optional 10x10 MHz outputs
  • 0.001 ppm aging in 10 years (Rubidium)
  • Ideal for telecommunication test systems and calibration laboratories
