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.
