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

With advances in digital signal processing techniques modern wireless communications systems and radar systems have become increasingly digital and more constraints have been placed on packing more information into less and less bandwidth. On the wireless side, modulation formats have become more complicated with less margin for symbol error. On the radar side, modern radar systems are trying to extract more information about the targets they track and provide the ability to track slow moving targets such as automobiles and personnel in the presence of clutter.For both communications and radar systems one of the key RF parameters that limits system performance is phase noise. As systems engineers develop new and more advanced RF systems, phase noise of oscillators and transmitters can no longer be overlooked.This application note will focus on phase noise measurements for pulsed RF carriers such as those used for radar systems. We will address some of the physical limitations relating to pulsed phase noise measurement and introduce the capabilities of the new Rohde & Schwarz FSWP phase noise analyzer.

As phase noise becomes an increasingly important system-level specification for electronic test equipment, communications systems, and radar systems. It is not only important to quantify the noise produced by oscillators, but also the noise added by each component in the signal processing chain. This application note reviews the fundamentals of residual or additive noise and addresses measurement techniques for determining the amplitude (AM) and phase noise added by two-port devices such as: amplifiers, mixers, block frequency converters, multipliers, dividers, and frequency synthesizers.Additionally, the Rohde & Schwarz FSWP phase noise analyzer will be introduced and a discussion of residual noise measurement techniques for the above-mentioned devices will be provided.
