The Rohde & Schwarz SMB100A is the ideal replacement in test circuits for fixed-frequency high-end crystal oscillators, which are often used as a reference signal. The device combines the same or even improved signal power with adjustable frequency and level. To further improve near-phase noise and frequency stability, two different OCXO reference oscillators are available.
The Rohde & Schwarz SMB-B1H in particular offers excellent performance that is unprecedented in this class.
