The 908 and 909 Frequency References 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 Frequency References 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 Frequency Reference Standard offers a more cost-effective solution than a central reference with a costly distribution system.
Features:
-Accurate reference "Atomic clock" in automated test systems
-Affordable and very cost effective
-Designed for portability with optional carrying case
-No need for battery backup during transportation
-Fast warm-up time
