Pendulum Instruments

Crystal oven standard model; 5x 10 MHz and 1x 5MHz outputs

The Pendulum Frequency References; model 6689 with a Rubidium clock and model 6688 with a high-stability ovencontrolled crystal oscillator, are designed for use in test systems, where a very high stability frequency reference is required and where multiple instruments or testers need to be supplied.

The Frequency References are also suited in calibration laboratories for calibrating various instrumentation, like frequency counters and synthesizers. The 6689 Rubidium Reference can be used as a primary lab reference, ensuring a frequency drift due to aging of less than 0.001 ppm during 10 years.
