The 908 and 909 are ideal for use in calibration laboratories where there is a specific need to calibrate a wide range of instruments, such as frequency counters and synthesizers. Unlike off-air frequency receivers, the 908 and 909 have excellent short-term stability that enables much faster frequency calibration.

If frequency standards are located in several departments, spread over a number of buildings, you will discover the portable 909 Rubidium standard offers a more cost-effective solution than a central reference with a costly distribution system.
