ULTRA STABLE OSCILLATOR (USO) | 10-13 SHORT-TERM STABILITY CLASS OCXO Issue: A4, 51001807.110, 5 July 2024 Specifications are subject to change without notice Copyright © 2014 to 2024, Rakon Limited. All rights reserved Page 1 of 3 Contact Us HSO13 The Ground USO HSO13 is a High Stability Oscillator (HSO) specifically designed to meet the stringent requirements of calibration and metrology laboratories, as well as high-performance applications such as master clocks and ground stations. This 10-11 stability class USO exhibits impressive short-term stability (Allan Standard Deviation, ADEV) of 8 x 10-14. It delivers excellent close-in phase noise (e.g., <-130 dBc/Hz at 1 Hz offset, 5 MHz). The HSO13 is a high performance reference oscillator ideal for scenarios that require highly stable frequency stability, reliable signals and excellent ADEV performance. It is available in the following frequencies: 5 MHz or 10 MHz. Allan Deviation (ADEV) at 5 MHz Phase Noise ζ (f) at 5 MHz Features Applications 67 x 60 x 40 mm  Frequency: 5 or 10 MHz  Short-term stability: 8 x 10-14 at 5 and 10 MHz  Frequency stability: ± 5 x 10-11 over 0 to +50°C  Supply voltage: 24 V (12 V available on request)  Ageing: ±5 x 10-11 (±50 ppt) per day  Master clocks  Reference oscillator for laboratories  Ground stations PTH1 -120 -130 -140 -150 -160 -170 -180 -110 Phase Noise (dBc/Hz) -100 -90 -80 -70 Phase Noise ζ (f) 100k 100 0.1 0.01 10k Frequency (Hz) Allan Deviation (ADEV) 1E-14 1E-13 1E-11 1E-12 Sigma (σy) 100000s 1000s 100s 10s 10000s Tau (T) Z Y X
