WR Trigger Distribution for distributed oscilloscope (CERN)
WR Trigger Distribution allows for spacial distribution between the source of a trigger and the location at which an input signal is observed. At CERN, many analogue signals coming from accelerators are digitized to allow for their monitoring. Signals coming from different parts of the machines must be correlated and can be sources of triggers.…

RF over WR to control accelerating cavities (CERN)
RF over WR allows real-time transmission of frequency tuning words over a WR network. These control words are then used to synthesize phase-aligned radio-frequency (RF) signals in different locations. These RF signals drive accelerating cavities in the Super Proton Synchrotron (SPS) at CERN. In this system, WR is used to distribute the base phase-aligned WR…
