Given an accurate manufacturing process, the same result will be obtained from real measurements with the R&S®ZNB when the hardware is tuned to match the simulated coupling matrix. The filter model was designed with CST Filter Designer 3D and simulated with CST Studio Suite®. This provides the necessary information to optimize the filter hardware through its tuning mechanisms such as screws, variable capacitors and varactor diodes.

Error bars indicate to what extent couplings and selfresonances are detuned.Based on the selected filter topology, the software extracts a coupling matrix from the measured S-parameters.The software automatically reads the measured data in realtime Establish a remote connection between CST Filter Designer 3D running on a PC and the R&S®ZNB vector network analyzer.Calibrate the R&S®ZNB vector network analyzer and perform S-parameter measurements on the DUT.Optional dynamic range enhancements deliver a dynamic range as high as 150 dB (real dynamic range without receivers going into compression at low transmission coefficients).įully integrated and easy to use There are four steps to tune a filter: The R&S®ZNB base unit provides typically 140 dB dynamic range (at 10 Hz IF bandwidth), which outperforms other, comparable products on the market. Furthermore, the R&S®ZNB vector network analyzer combines high power handling capacity with high sensitivity and low trace noise. It combines high measurement accuracy with exceptional speed – better than 5 μs per point.

The R&S®ZNB is the leading vector network analyzer for production environments with a focus on speed, dynamic range and ease of operation. For real-world tuning, CST Studio Suite® supports USB, socket and Ethernet connections for a wide range of Rohde & Schwarz vector network analyzers.
