▲ R&S ZNL14 Demonstration Unit

The R&S ZNL14 is a benchtop Vector Network Analyzer designed to measure RF network parameters in two-port configurations. It is widely used in the communications industry and by leading network service providers in Thailand.

The ZNL14 supports frequencies up to 14 GHz, covering RF and microwave measurement applications such as, cable testing, antenna measurement, filter testing, wireless communication modules. This makes it suitable for research, development, and production quality inspection.

One of the key advantages of the ZNL14 is its compact and lightweight design with a built-in handle, making it easy to move between laboratories or transport to field sites. The instrument also features a built-in battery, enabling field measurements without a constant power supply. The battery allows operation for approximately 3.5 hours, making it ideal for environments where power access is limited or mobility is required.

Additionally, the ZNL14 features a 10.1-inch multi-touch display, allowing users to quickly configure settings, adjust frequency ranges, and perform calibration. The intuitive interface reduces the learning curve and allows engineers to focus on analyzing measurement results.

3-in-1 Instrument – Multiple Functions in One Device

One of the main advantages of the R&S ZNL14 is its ability to perform multiple measurement functions within a single instrument.
✓ Vector Network Analyzer (VNA)
Supports S-parameter measurements such as S11 and S21 to analyze Return Loss, VSWR, and Insertion Loss. Ideal for testing coaxial cables, antennas, filters, and RF components.
✓ Spectrum Analyzer (Option ZNL-K1)
Spectrum analysis functionality can be added through an optional upgrade, reducing the need for multiple instruments.
✓ Power Meter
Supports connection with external power sensors for precise signal power measurements.

▲ Calibration Accessories

This multi-function capability reduces equipment costs, installation space, and system complexity.
The ZNL14 is suitable for:
・RF and microwave engineers for design and testing
・Research laboratories and field engineering teams
・RF/microwave equipment manufacturers
・Educational institutions teaching RF signal measurement

To help customers evaluate the suitability of the instrument, demonstration units are available. The device can be demonstrated directly at the customer's site, whether in laboratories or field environments. We also provide technical consultation, installation support, and basic troubleshooting services.
