REF10 SE120 Master Reference Clock

Introduced 2017$6,249 MSRP

The Mutec REF10 SE120 is an enhanced version of Mutec's REF10 that uses a more elaborately manufactured, hand-selected oven-controlled crystal oscillator (OCXO) made in Germany, delivering what the manufacturer describes as among the lowest phase-noise and jitter figures in its class. It outputs eight simultaneous, galvanically isolated, individually switchable 10 MHz reference clock signals across both 50Ω and 75Ω BNC connectors.
