Rohde & Schwarz’s ZNH is a full two-port handheld vector network analyser up to 26.5GHz with cable and antenna analysis and full S-parameter measurements as standard. It is user-friendly, easy to configure and has a compact fanless housing for field applications.

The device helps detect and remedy defective RF cables and communications system components. It can also characterise components up to 26.5GHz in the field or lab, and has a built-in receiver step attenuator at both ports, protecting it from overloading. The ZNH’s four-receiver architecture supports unknown through, open, short and match (UOSM) calibrations. Best-in-class 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 ideal 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 enable field engineers to maintain and swiftly restore radar and satellite systems. The options are provided using a software keycode.

Weighing just 3kg, the ZNH has a small form factor, fanless design, long battery life and widely spaced large keys for comfortable operation with gloves, making it convenient for work in the field. The 7in multi-touch display uses smart touch gestures, similar to smartphones in lab applications. The ZNH is simple and user-friendly to operate. Novice users can operate the analyzer with no previous training. 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 ideal 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 antennas.
