10 Channel OCXO Low Phase Noise Rubidium Frequency Reference

The phase noise for a standard Rubidium source is not acceptable for some applications. Our low noise Rubidium frequency reference incorporates a low noise OCXO that is locked to the Rubidium source. This combination gives you the best of two technologies - the stability of Rubidium and the low noise of an OCXO. This single rack unit chassis, having ten channels, frequently meets the needs of complex systems and often eliminates the need for a distribution amplifer.
