Highly-scalable entry-level network analysis solution

Livingston has further extended its broad portfolio of RF test equipment with the inclusion of the latest Rohde & Schwarz two-port vector network analyser. The R&S ZND is an entry-level analyser product for evaluating the performance of RF systems and components in manufacturing facilities and development laboratories, or validating antenna installations.

The instrument is capable of delivering accurate measurements on the magnitude or phase of network scattering parameters - known as S parameters. Supporting a typical dynamic range of 120dB, it presents users with a maximum bandwidth of 300kHz. Furthermore, it can deliver a power sweep spanning up to 48dB. A 12.1-inch touch-enabled display facilities trouble-free, intuitive operation based on the Windows 7 operating system. Through this it is straight forward to handle multiple traces simultaneously.

The R&S ZND occupies a lower price bracket than competing solutions, but with the features and functionality expected on a mid-range model. It has the same look and feel that many engineers will be familiar with from the R&S ZNB series, thereby allowing almost seamless transition and code compatibility. There is a great deal of scope by which to upgrade, so that test engineers are in a position to add extra elements as and when this is mandated by means of a software keycode. The standard unit can address unidirectional (S11 and S21) S-parameters across a frequency range from 100kHz to 4.5GHz. Upgraded units are able to perform bidirectional measurements (covering S11, S12, S21 and S22) up to frequencies reaching 8.5GHz. R&S ZND units can also be controlled via LAN or GPIB interfaces, in order that measurements can be configured and test results viewed remotely. Results can be easily saved onto a USB memory stick for offline analysis, says the company.

“On production lines, it is vital that RF testing can be carried out with a high degree of accuracy and in the shortest time possible, otherwise there are likely to be crippling cost penalties to contend with,” said Mike Mchale, UK sales director, Livingston. “Thanks to the R&S®ZND’s simple to use human-machine interface, high throughput can be maintained and the chances of errors being made are reduced to almost zero. By sourcing this equipment on a rental basis, engineers can not only benefit from the well-defined upgrade path of this product, but can also lower or raise the number of units they have in operation to better fit their production output, as well as having provision for new wireless standards as they emerge.”
