Key Features
Portable VNA to 26.5 GHz
Three handheld models cover 14 GHz, 20 GHz and 26.5 GHz for field RF components, antenna systems, transmission lines, tower amplifiers and microwave assemblies.
Standard 2-port Network Analysis
Supports full S-parameter workflows, differential-parameter measurement, receiver measurement, Smith chart, impedance conversion and port-matching debugging.
CAT and Distance-to-Fault Workflows
Cable and antenna test mode is standard for VSWR, return loss, single-port cable loss, antenna matching and distance-to-fault measurements during installation and maintenance.
Bias-Tee and GPS Included
Standard bias-tee support helps power external measured objects, while GPS/time/location logging records field measurement position for site reports and traceability.
Field-ready Mechanical Package
The 8.4-inch multi-touch screen, 4-hour working time, 3.2 kg net weight and portable package are aimed at outdoor, narrow-space and aerial-work measurement conditions.
Expandable Analysis Modes
Spectrum analysis, time-domain analysis, enhanced TDR, pulse measurement, scalar mixer measurement and frequency-offset workflows are available depending on configuration.

Applications
Antenna and Feedline Maintenance
Measure return loss, VSWR, cable loss and distance-to-fault at tower sites and remote RF installations.
RF Component Characterization
Use 2-port S-parameters for filters, cables, connectors, attenuators, amplifiers and microwave assemblies up to 26.5 GHz.
Line-side Acceptance Test
Portable VNA workflows support RF assembly verification where moving a full bench VNA is impractical.
Automotive Electronics and RF Systems
Characterize cables, antennas, RF modules and high-frequency interconnects used in vehicle electronics development.
Cable Fault Location
DTF and time-domain workflows help locate connector damage, cable discontinuities and installation-related faults.
Field-to-Lab Correlation
Record GPS/time/location-tagged results in the field and compare against lab measurements for maintenance and acceptance reports.
