A Detection of Red Noise in PSR J18242452A and Projections for PSR B1937+21 using NICER X-ray Timing Data
Jeffrey S. Hazboun, Jack Crump, Andrea N. Lommen +17
We have used X-ray data from the Neutron Star Interior Composition Explorer (NICER) to search for long time-scale, correlated variations ("red noise") in the pulse times of arrival…
Cross-spectrum noise measurements at 4 K to minimize power-splitter anti-correlation effect
Archita Hati, Craig W. Nelson, David Pappas +1
We report an accurate measurement of the phase noise of a thermally limited electronic oscillator at 300 K. By thermally limited we mean that the white signal-to-noise ratio of the…
Cross-spectrum Measurement of Thermal-noise Limited Oscillators
Archita Hati, Craig W. Nelson, David A. Howe
Cross-spectrum analysis is a commonly-used technique for the detection of phase and amplitude noise of a signal in the presence of interfering noise. It extracts the desired correl…
An integrated low phase noise radiation-pressure-driven optomechanical oscillator chipset
X. Luan, Y. Huang, Y. Li +13
High-quality frequency references are the cornerstones in position, navigation and timing applications of both scientific and commercial domains. Optomechanical oscillators, with d…
PM noise Measurement at W-Band
A. Hati, C. W. Nelson, D. A. Howe
We present improved performance for a 92 to 96 GHz cross-spectrum phase modulated (PM) noise measurement system reported. The system is principally designed to measure amplifiers i…
PM noise of a 40 GHz air-dielectric cavity oscillator
Archita Hati, Craig W. Nelson, B. Riddle +1
We describe the design of a low-phase-modulated (PM) noise, 40 GHz oscillator that uses a conventional air-dielectric cavity resonator as a frequency discriminator to improve the P…
Phase inversion and collapse of the cross-spectral function
Craig W. Nelson, Archita Hati, David A. Howe
Cross-spectral analysis is a mathematical tool for extracting the power spectral density of a correlated signal from two time series in the presence of uncorrelated interfering sig…
Feedback and harmonic locking of slot-type optomechanical oscillators to external low-noise reference clocks
Jiangjun Zheng, Ying Li, Noam Goldberg +8
We demonstrate feedback and harmonic locking of chip-scale slot-type optomechanical oscillators to external low-noise reference clocks, with suppressed timing jitter by three order…
