   * Synchronization: All USRPs are connected to a stack of octoclocks (see below for more info) and can be configured to work in synchronized mode by selecting ''external clock source'' in the USRP sink or source configuration.

 # Octoclocks
 A hierarchy of octoclocks allow the reference and timing distribution to all USRPs in CorteXlab. All cables are of same length (5m between master and slave octoclocks and 10m between slave octoclocks and USRPs). The connection layout is as shown below. The octoclock 0 is the master and the octoclocks 1-4 are the slave ones.
