Vector network analyser provides economical uni- and bidirectional measurements

September 10, 2014 // By Graham Prophet
RF component production lines have to maintain high throughput while carrying out S parameter measurements on antennas and filters. Rohde & Schwarz developed the R&S ZND for this testing requirement; an attractively priced vector network analyser that is easy to operate.

The ZND has two test ports, and the base unit is designed for unidirectional measurements from 100 kHz to 4.5 GHz. Its options provide for flexible upgrades. The frequency range can be extended to 8.5 GHz, and the instrument can be equipped for bidirectional measurements up to 4.5 GHz or 8.5 GHz. These functions can be locally activated.

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

The analyser's 30 cm (12.1-in.) touchscreen and intuitive user interface make it 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 function allows users to configure the ZND very quickly, and touchscreen tabs 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 ZND vector network analyser joins the Rohde & Schwarz Value Instruments portfolio of T&M equipment.
