Ultra-Stable Multi-Reference


SKU: FRXO100 Category:


New from DS Instruments for 2020, the FRXO100 is an ultra-stable, high-performance, compact multi-output reference frequency source. Using its high-stability oven-controlled 10MHz oscillator, the FRXO100 provides four 10MHz outputs, and 2 phase-locked 100MHZ ultra-low phase-noise outputs. Compact and simple-to-use, the FRXO100 is powered from standard USB-C, and is controllable from a host PC.

Easy stand-alone usage with a USB power adapter.
