Keysight-Agilent 5061A

Cesium Beam Frequency Standard

The Agilent HP 5061A Cesium Beam Frequency Standard carries on this world-class tradition. Sold-state components and the closed-loop, self-checking control circuit yield an accuracy of +/-1 x 10E-11.
Outputs available include: 5MHz, 1MHz, and a 100kHz signal for integrating applications such as use with a clock.

This high accuracy is combined with excellent reliability, making the Agilent HP 5061A ideal for use as a reference standard in national laboratories plus many other applications requiring accurate frequencies. Front panel controls provide a circuit check switch and a meter for monitoring performance. Front panel lights are also provided to indicate any interruption of continuous operation, and that the crystal oscillator is locked to the atomic resonance. If you need accuracy, you need the 5061A!
