    4545===== Synchronized Clock Reference (Octoclock) =====
    4646
    47 The Massive-MIMO mini-racks and several SDRs in the grid are connected to a GPS-disciplined clock reference system which gives the SDRs PPS (pulse per second) and 10MHz reference signals for synchronizing their internal oscillators. A tree-like topology with equal length cables ensures minimal deviation of the reference signals between connected devices. The following nodes are currently connected to this clock reference system:
