R&S adds functions free of charge to handheld vector network analyser

A two-port vector network analyser (VNA), the ZNH, has cable and antenna analysis and full S-parameter measurements included as standard, without charge. The VNA can characterise components up to 26.5GHz in the field and lab.

It helps detect and remedy defective RF cables and communications system components. Rohde & Schwarz has included the essential functions, such as cable and antenna measurements and full two-port S-parameter measurements, with a built-in receiver step attenuator at both ports that protects it from overloading.

The four-receiver architecture supports unknown through, open, short and match (UOSM) calibrations. RF performance features such as low trace noise (0,0025dB RMS), 100dB dynamic range, 0dBm typical maximum output power and 16,001 measurement points make the ZNH suitable for installing and maintaining RF communications systems and characterising basic RF components.

Additional options such as a power meter, pulse measurement, wave ratio and wave quantities are available to enable field engineers to maintain and restore radar and satellite systems. The options are provided using a software keycode.

The ZNH weighs 3.0kg. The small form factor is a fanless design, long battery life and widely spaced large keys for operation with gloves. The 7.0 inch multi-touch display uses smart touch gestures similar to smartphones in lab applications for ease of operation.

Novice users can operate the analyser with no previous training, says Rohde & Schwarz. The wizard function enables pre-configuration of test sequences, reducing on-site errors. Free InstrumentView and MobileView software enables measured data to be forwarded straight from the field to the lab for parallel analysis.

The handheld ZNH is also suitable for R&D labs, production lines and universities, where space and budgets are limited, and for measuring RF components in production environments such as filters, amplifiers, cables, connectors and antennae.

The handheld vector network analyser R&S ZNH is available now.
