Overview
The AEM Networks 26.5 GHz Handheld VNA & TDR Adapter transforms the portable TestPro platform into a high-frequency, dual-mode test solution for laboratory, production and field environments. Operating from 1 MHz to 26.5 GHz, it brings advanced RF measurement capability closer to where cables, harnesses and interconnects are actually built, installed and maintained – reducing dependence on dedicated laboratory equipment.

Designed around two distinct operating modes, the adapter combines full 2-port Vector Network Analysis with handheld TDR diagnostics in a single platform.
Generic VNA Mode (PC-Controlled)
Generic VNA mode provides complete S-parameter measurements – S11, S12, S21 and S22 – while Handheld TDR Mode supports TDR, Return Loss and Insertion Loss testing with configurable PASS/FAIL limits, harness profiles and fault-location tools.
Handheld TDR Tester Mode (Standalone)
With 13 ps / approximately 3.8 mm TDR spatial resolution, battery-powered portability and support for high-frequency automotive, telecom, aerospace, military and R&D applications, the adapter bridges the gap between lab-grade measurement and practical field deployment. Its combination of high bandwidth, detailed fault visibility and flexible deployment makes advanced signal-integrity testing more accessible across production lines, service environments and remote sites.
