HIGH RELIABILITY 10-10 STABILITY CLASS OCXO | ULTRA STABLE OSCILLATOR SERIES Issue: A4, 51001205, 5 July 2024 Specifications are subject to change without notice Copyright © 2012 to 2024 Rakon Limited. All rights reserved Page 1 of 4 Contact Us RK410 Mini USO The RK410 is a 10-10 stability class Mini USO (Ultra Stable Oscillator) designed specifically for space applications. This high reliability compact Space OCXO delivers an outstanding frequency stability of ±0.5 ppb (under vacuum). Its short-term stability (ADEV) achieves 2 x 10-13 at tau = 1s, and the ±20 ppb/year long-term stability is guaranteed. Operating in harsh environments , the RK410 Mini USO is able to deliver a stable frequency source for over 15 years, making it a qualified reference oscillator. It is a great solution for any application for which stable frequency signals and accurate timing performances are crucial, such as precision instruments, altimeters, navigation and positioning systems.
