Software tool for fast and repeatable optimization of signal analyzer RF front-end settings
The signal conditioning in the RF front-end of signal analyzers is crucial to achieve the best performance with respect to image-suppression, noise-floor, dynamic range and other RF-key parameters.Precise signal levelling is especially important for complex measurements like Error-Vector-Magnitude (EVM). To minimize the measurement uncertainty from test system contributions over a wide range of different levels, the RF front-end needs to be adapted continuously according to the signal characteristics, signal power and frequency - ideally using an automatic levelling algorithm.This document describes the approach of a waveform specific, on-site characterization of the signal analyzer: For each waveform and frequency of interest, the instrument is evaluated in a first step. With this additional data, a fast and repeatable auto-levelling can be performed during the actual measurement.

Next generation technologies in radar and satellite communication with high data rates call for innovative testing solutions to develop and manufacture RF components like voltage controlled oscillators (VCO). The R&S®FSPN phase noise analyzer increases efficiency and reproducibility of VCO characterization and phase noise measurements from lab to production.Voltage controlled oscillators are oscillators whose output frequency is controlled by means of an external tuning voltage, and they are used in a wide variety of electronic and RF applications like function generators, phase-locked loops including frequency synthesizers used in communication equipment. Different VCO design approaches yield different parameters and performance, and therefore it is important to measure or characterize VCOs under different conditions. This application note provides a short technical introduction to voltage controlled oscillators and explains the most common and the most important measurements made during the VCO characterization process.
