Home  /  Products  /  Frequency and Time Reference Standards  /  Rubidium, Frequency Ref., 4210A


The ptf 4210A Rubidium Frequency Standard is a unique solution for providing a highly stable, low phase noise, frequency reference for applications requiring atomic reference stability performance.
The instrument contains a high performance rubidium module, with an extended life design, and very low aging rate, with high quality OCXO o/p for low phase noise.
For even better long term stability the unit will accept a 1PPS input that can be derived from a reference such as caesium or GPS.
An ideal laboratory or system frequency reference, which includes a range of options are available to enhance the functionality of the unit.
