Vector Network Analyzers


A vectorial network analyzer (VNA) records the amplitude and phase position as a complex variable and can therefore also express the S-parameters as complex values. Strictly speaking, no vectors are measured, but the phasor, composed of a magnitude and an angle. Each type of network analyzer measures and relates both the test signal it generates and the response signal modified by the DUT. As a result, the absolute value measurement, which is complex for high accuracy requirements, can generally be reduced to the relative measurement, which can be implemented with less expenditure.

We offer network analyzers with a bandwidth of up to 8.5 GHz. The network analyzers are suitable for broadcast monitoring/evaluation, site survey, S-parameter measurement, cable and antenna test, analog/digital modulation analysis, EMI pre-compliance test, research and development, education, production and maintenance and more applications.
