For a high stability clock version choose RSA50655N-OCXO. It offers an initial calibration accuracy of <0.1ppm, with a temperature stability of <.005 ppm and <0.03ppm ageing/yr.

The Rigol RSA5065N-OCXO Real Time Spectrum Analyzer With Vector Network Analysis offers real-time signal analysis and VNA capabilities up to 6.5 GHz. Built on Rigol’s Ultra Real platform, the RSA5065N offers S11 and S21 reflection and transmission analysis. This advanced specification analyzer provides multi-touch user control via the 10.1” LCD touchscreen, with front panel buttons, keyboard, and mouse input also available for a straightforward user interface. The RSA5065N runs a Linux operating system to provide a reliable and stable interface, while remote communication interfaces are also available.  

Customers needing to characterize active or passive components, identify signal path errors or tune antennas will benefit from this VNA solution, which enables complex measurements including distance to fault and S parameters.  S11, or forward reflection co-efficient allows engineers to quickly visualize and measure their component’s response on a Smith chart and polar plane while measuring their component’s magnitude and SWR. This is important when characterizing the performance of passive components like attenuators, splitters, and filters. S21, or forward transmission coefficient allows engineers to quickly visualize how their components, including amplifiers, filters and cabling, affect impedance or phase as a function of frequency. View phase or group delay as a function of frequency, as well as magnitude to quickly determine and confirm critical specifications. Distance to fault measurements allow engineers to easily debug connectivity issues that cannot be seen from visual inspection. The spectrum analyzer uses signal reflections to calculates the distance to a fault anomaly.  It is useful debugging communications system and completing cable test as well as optimize performance and throughput of a network. The Vector Network Analysis mode complements the other analysis capabilities of Rigol’s Ultra Real spectrum analyzers, including the advanced measurements in Smith mode, real time visualization, EMI pre-compliance analysis, and vector signal analysis tests. An optional Preamp adds 20dB gain to input signals.

The RSA5000 series measurement possibilities include EMI, RTSA, VSA, and VNA modes in addition to the traditional GPSA mode. Engineers may find it convenient to address multiple RF test challenges with just one instrument, effectively reducing their time and costs, greatly improving their working efficiency.
