Timing components such as low jitter oscillators and clocks are necessary to facilitate increasing data rates in high speed digital designs. As part of the overall system design, the components also have to perform in the system’s non-ideal power integrity environment and limit the power supply induced phase noise and jitter from power rail disturbances. Measuring the power supply noise rejection (PSNR) requires accurate generation and leveling of artificial, sinusoidal disturbances and measurement of resulting phase-noise and jitter impairments.

With recent enhancements in semiconductor technology the microwave frequency range beyond 50 GHz becomes more and more attractive especially for wideband communication applications like 802.11ad, microwave links or automotive RADAR. Low phase noise is essential for these applications to work properly. Accurate measurement of phase noise is needed to improve the performance. However, test setups at these frequencies become difficult, especially when cross correlation of two receive paths is needed to suppress additional phase noise added by the local oscillators or mixer stages. Two external harmonic mixers in combination with a commercially available phase noise tester are used for phase noise analysis. Signal sources with frequencies up to 325 GHz can theoretically be measured with this setup.

This paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for example for automotive RADAR sensors at 80 GHz using the interferometric measurement approach in combination with a phase noise and VCO tester R&S FSWP. The setup provides a way to characterize the additive/residual phase noise of amplifiers down to -150 dBc/Hz at 100 kHz offset even in the microwave range at 80 GHz.

For automated test applications, measurement time is often as important as the quality of the measurement. As with many situations, time is money. In practice, phase noise measurements are generally not considered fast, but test engineers still desire to save as much test time as possible. The Rohde & Schwarz®FSWP (FSWP) is a modern, digital signal processing based, phase-noise test set that performs many tasks in parallel in an effort to improve measurements speed. However, several measurement settings drastically affect measurement speed. This paper will discuss these settings and provide suggestions on improving overall measurement speed.The three key instrument parameters that affect FSWP measurement speed are:1. Number of cross correlations2. Resolution bandwidth (RBW)3. Offset frequency span
