Pendulum 6688 Series Stand-alone Frequency Standard

Ideal Reference for Multiple Testers ​

These Pendulum frequency standards 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 companies, especially when multiple instruments/testers need to be supplied with a stable frequency reference. 

The very short warm-up time of only 10 minutes makes these units suitable also for field use.
