Product overview
The R&S®ZNH is a compact, full-function two-port handheld vector network analyzer — low in complexity, high in precision. It covers one-port cable and antenna measurements as well as full two-port S-parameter measurements, and its four-receiver architecture supports advanced UOSM calibration, which is what keeps field measurements accurate. A capacitive multitouch screen answers smartphone-like gestures while hard keys stay usable with gloves on, so the instrument is easy to drive and dependable on site. A settings overview menu keeps setup short, and remote control is available from PC, Android and iOS apps — for characterizing cables, antennas, filters and components in the field.
Key features
- Four-receiver architecture supporting UOSM (unknown through, open, short, match) calibration, which lifts accuracy in the field
- 100 dB (typ.) dynamic range, enough for filter isolation and antenna measurements
- Very low trace noise: magnitude 0.0015–0.0040 dB RMS, phase 0.02°–0.04° RMS
- Capacitive multitouch interface with pinch and swipe gestures; hard keys that work with gloves on
- Settings overview menu and a measurement wizard, which automate a test sequence and cut out setup steps
- Ruggedized housing (IP51), small and light, with a non-reflective display, built for work outdoors
- Standard functions cover one-port cable loss, reflection and transmission measurements, distance-to-fault, and all four S-parameters (S11/S12/S21/S22)
- Remote control from PC, Android and iOS apps
Typical applications
- Cable and antenna measurements in the field: cable loss, VSWR, return loss and distance-to-fault diagnosis when installing and maintaining base stations, broadcast and communications systems
- Filter and antenna isolation test: passband and stopband characteristics and isolation between antennas, for acceptance and troubleshooting in communications and wireless infrastructure
- S-parameter component characterization: full S11/S12/S21/S22 measurement and analysis of amplifiers, attenuators, power dividers and other two-port components
- Distance-to-fault diagnosis: time domain reflectometry pinpoints breaks, shorts and impedance discontinuities in a cable, which speeds up a repair
- Aerospace and defense field test: a ruggedized design (IP51) and coverage to 26.5 GHz, for verifying airborne, shipboard and ground RF systems in harsh conditions
