The O-30C-HF is an OCXO with the best possible phase noise, particularly close to the carrier, with low sensitivity to vibration (G-Sensitivity) and very good frequency stability.
In addition, this OCXO has very good short-term stability
The OCXO is housed in a robust, hermetically sealed metal housing (36 mm x 27 mm) and is therefore ideally suited to harsh environmental conditions.
