Testing Insertion Loss Of PCB Signal Structures With Delta-L 4.0
7/20/2022
Delta‑L is an algorithm easily removes effects and calculating the insertion loss per inch of a PCB trace from measurements of test coupons with different lengths. The Delta‑L measurement workflow is fully integrated in the R&S®ZNA, R&S®ZNB, R&S®ZNBT and R&S®ZND vector network analyzers as the R&S®ZNx-K231 option.

Linearization Of RF Amplifiers
7/5/2022
This white paper focuses on linearization of a non-linear device, in our case the RF power amplifier. It is shown how simulation and the integrated functions of the Rohde & Schwarz instruments R&S®SMW200A and R&S®FSW work hand-in-hand with the simulation capabilities from MathWorks in MATLAB / Simulink.

Two-Port Residual Noise Measurements
6/2/2022
Radar systems engineers were once happy simply to detect targets but, today, the target's extremely small return signal must also be extracted from high amplitude ground or sea clutter. Radar system phase noise is the key parameter defining a radar's ability to extract small signals from a noisy background.

Modulation Measurement Optimizer
5/20/2022
This document describes the approach of a waveform specific, on-site characterization of the 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.
