53100A Phase Noise Analyzer

Radar systems and aircraft timing references require low-noise oscillators for mixing signals at X-band and beyond with minimal distortion. We designed the 53100A phase noise analyzer for close-in phase noise characterization of oscillators, including high-performance quartz and atomic frequency standards. In the past, these types of measurements required several calibration steps that included a reference oscillator at the same nominal frequency as the Device Under Test (DUT). But with the 53100A, a single reference oscillator can measure a DUT at any frequency thanks to the direct digital design. Furthermore, the cross-correlation design removes calibration steps that often lead to measurement errors and repeated test runs.
One big challenge in measuring high-performance oscillator technology is finding a reference oscillator with suitable performance to appropriately characterize the technology. With the 53100A, you don’t need access to a high-performance atomic clock to characterize a device with cutting-edge phase noise performance. By simply employing two decent reference oscillators instead of one, you can reach the limits of the 53100A’s measurement floor. Read our latest white paper describing this approach. It contrasts a measurement using a very high-performance reference versus using two “ordinary” oscillators.

Another challenge for systems featuring RF and microwave timing systems is finding a single instrument to measure both frequency ranges. While the 53100A can measure signals up to 200 MHz out of the box, we recently enhanced the software to allow external frequency down-conversion to accurately measure VHF and microwave signals. This paper contrasts frequency division with down-conversion techniques and presents a high-performance, cost-effective solution.

Sponsorship & Featured Speakers at ITSF

We were proud to be a Diamond sponsor of the 2021 International Timing and Sync Forum (ITSF). The event was held in person on November 1–4, 2021 in Brighton, UK. This is the largest global conference that focuses on timing and synchronization and featured strong attendance from industry experts and participants from 38 countries. Our Frequency and Timing Systems (FTS) team hosted tutorials on day 1 of the forum followed by six presentations and one poster session.
Data Center Timing White Paper

Regulatory and user requirements for data centers demand sub-microsecond sequential time stamps. Time stamping precision and accuracy is critical not only across servers in a data center, but also between data centers in a network. Read our white paper to explore the requirements and our solutions for precise, resilient and secure data center server synchronization.
Above and Beyond COTS with Space CSAC (Chip Scale Atomic Clock)

Market predictions indicate significant growth in the number of satellites launched over the next decade into Low Earth Orbit (LEO) for telecom, defense and Earth observation. Released June of 2018, the industry’s first commercially available radiation-tolerant CSAC is ideally suited for LEO applications and provides the accuracy and stability of atomic clock technology critical to many defense and Earth observation applications. The space CSAC is a Commercial Off-the-Shelf (COTS) part manufactured to IPC-610 Class 2 standards that utilizes commercial electronic components that are radiation tolerant to 20 krad and 64 MeV. For more info, visit our space CSAC web page, read the full article in our Space Brief newsletter or watch our space CSAC livestream video.
