Description

Vector Network Analyzers (VNAs) are precision RF and microwave testing instruments designed to measure, analyse, and characterise the electrical performance of electronic components, devices, and communication systems. They are widely used for evaluating S-parameters, including reflection and transmission characteristics, return loss, insertion loss, impedance, and phase response across a broad frequency spectrum. These instruments provide highly accurate measurements, excellent dynamic range, fast measurement speeds, and advanced analysis capabilities, making them suitable for demanding RF and microwave testing environments. Designed to support research, development, manufacturing, and quality control, VNAs help engineers evaluate the performance, reliability, and signal integrity of RF components. Advanced measurement functions such as time-domain analysis, device modelling, automatic calibration, and high-resolution measurements enable detailed characterisation of complex electronic systems. Depending on the model, frequency coverage can extend from 70 kHz to 70 GHz and beyond with suitable configurations.
