IMS - XHERb : External Holdover Expansion

PRS10 Rubidium Oscillator 
The Meinberg XHERb chassis adds superior holdover performance to the Meinberg IMS time and frequency systems. It contains either one or two PRS10 Rubidium modules from Stanford Research and can be eqipped with dual power supplies for each Rubidium module.


The module will be connected to the reference clock of the associated IMS chassis and the Rubidium will be steered as long as the reference clock is synchronized.

In case the reference clock loses its sync source, the XHE chassis provides the sync reference for IMS chassis based on its holdover performance.
