Rohde & Schwarz has introduced the R&S ZND that allows users in RF component production to maintain high throughput while carrying out S parameter measurements on antennas and filters. The vector network analyser features two test ports, and the base unit is designed for unidirectional measurements from 100kHz to 4.5GHz.

According to the company, its easy-to-use options provide for flexible upgrades. The frequency range can be extended to 8.5GHz, plus the instrument can be equipped for bidirectional measurements up to 4.5GHz or 8.5GHz. These functions can be locally activated.


The R&S ZND is geared for production line measurements such as characterisation of passive mobile phone components. The analyser enables users to easily measure S-parameters such as S11 on antennas or S21 on filters. The favourably priced, easy-to-operate instrument is also ideal for training purposes, added the company. The R&S ZND offers a specified dynamic range of up to 120dB and a specified power sweep range of up to 48dB. Options for time domain measurements, general purpose interface bus (GPIB) and a parts handler interface (handler I/O) are also available.

The analyser's 30cm touchscreen and intuitive user interface make it especially easy to configure measurements and analyse results. All instrument functions are accessible in no more than three operating steps via the soft panel. A toolbar and drag and drop functionality allow users to configure the R&S ZND very quickly, and touchscreen tabs make it simple to switch between instrument setups. Traces and channels can be arranged in any desired combination, enabling users to display results in a clear and straightforward manner even for complex measurements.

The instrument is available from Rohde & Schwarz.
