6688/ 6689

Achieve a stable frequency reference in calibration labs or test systems with the stand-alone high stability oven-controlled crystal oscillator found in the 6688 Stand-alone Frequency Standard. For greater stability employ the 6689 Stand-alone Rubidium Frequency Standard, ensuring frequency drift due to aging of less than 0.001 ppm per 10 year period.

• 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
