Increasing data rates in high-speed digital designs and wireless communications require SerDes PLLs and clock synthesizers with low additive phase noise and high jitter attenuation. Modern designs often follow a two-stage architecture, consisting of a jitter-attenuator and a frequency-synthesizer stage. Due to their high phase noise sensitivity, phase noise analyzers are the instruments of choice for these tests. To stimulate the PLL, an additional signal source with ultra low phase noise is required.

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

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.
