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.

Rohde & Schwarz is advancing its pioneering sub-THz research in the D-Band and has reached important milestones. In collaboration with the Berkeley Wireless Research Center (BWRC), the test and measurement expert has successfully characterized a TX/RX multi-antenna chip (CHARM) operating at up to 140 GHz, using their D-Band over-the-air (OTA) test chamber. Academia and industry leaders agree that the 110 GHz to 170 GHz frequency range, known as D-Band, is critical for beyond 5G and 6G mobile communications and future automotive radar applications.
