Rohde and Schwarz convertors have wider range

Rohde and Schwarz is launching high-end network analysers and millimetre-wave converters from a single source.

Following the successful launch of converters for the 75GHz to 110GHz range, the company is now offering converters for the ranges 50GHz to 75GHz and 220GHz to 325GHz.

The converters connect directly to analysers of the RandS ZVA series - no extra hardware is required.

Even multiport measurements up to 325GHz can be implemented for the first time.

Network analysis in the millimeter-wave range has - until now - been restricted to two-port measurements.

To carry out complete multiport measurements on devices such as couplers, for example, the ports had to be reconnected because it was not possible to measure all S-parameters simultaneously.

The four-port network analysers of the RandS ZVA family together with the Rohde and Schwarz converters for the V, W and J bands for the first-time enable measurements up to 325GHz with up to four ports.

Results are immediately available, and full multiport system error correction further enhances measurement accuracy.

On top of this, the converters offer maximum performance in terms of dynamic range, which exceeds 90dB at 75GHz and 60dB (typ 80dB) at 325 GHz.

This level of performance allows even high-blocking filters to be analysed.

Output power is adjustable, which facilitates tests on amplifiers in the development stage, for example.

All converters are fully integrated into the network analyser firmware, which means they can be operated as if they were part of the base unit.

Diagrams show the user how to connect the converters.

A function that automatically limits output power prevents damage to the converters.

The RandS ZVA-Z325 and RandS ZVA-Z75 millimeter-wave converters and the corresponding RandS ZV-WR03 and RandS ZV-WR15 calibration kits are now available from Rohde and Schwarz.
