The R&S ZNH is a full two-port handheld vector network analyser up to 26.5 GHz with cable and antenna analysis and full S-parameter measurements from Rohde & Schwarz.

Both of these functions are included free of charge. The R&S ZNH is user-friendly, easy to configure and has a compact fanless housing for field applications.

This vector network analyser helps detect and remedy defective RF cables and communications system components.

It can also characterise components up to 26.5 GHz in the field and lab. The R&S ZNH comes standard with essential functions, such as cable and antenna measurements and full 2-port S-parameter measurements.

The analyser also has a built-in receiver step attenuator at both ports that protects it from overloading.

Four-receiver architecture supports unknown through, open, short and match (UOSM) calibrations.

RF performance features such as low trace noise (0,0025 dB RMS), 100 dB dynamic range, 0 dBm typical maximum output power and 16,001 measurement points make the R&S ZNH ideal for installing and maintaining RF communications systems and characterising basic RF components.

Additional R&S ZNH 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 3 kg, the R&S 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 7-inch multi-touch display uses smart touch gestures similar to smartphones in lab applications.

The analyser is simple and user-friendly to operate.

Novice users can operate the analyser 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 R&S 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.

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