As operating frequencies increase, cable and connector integrity can no longer be assessed adequately using only low-frequency continuity or conventional cable tests. The 26.5 GHz Adapter is designed for applications where signal integrity, fault location and RF performance must be verified closer to the actual operating bandwidth of the system.
Automotive

Modern vehicles increasingly rely on high-speed data links connecting cameras, sensors, ADAS systems, battery management systems and other electronic subsystems. These networks place much greater demands on cable harnesses, connectors and terminations than conventional automotive wiring.
With support for OPEN Alliance and IEEE 802.3bw, 802.3bp and 802.3ch, the adapter enables engineers and technicians to validate automotive Ethernet assemblies and troubleshoot high-frequency harness problems directly on the production line or in the field. Its approximately 3.8 mm TDR spatial resolution provides the visibility needed to locate small discontinuities and connector-level defects within increasingly dense harness architectures.
Typical applications include:
- ADAS cable and connector validation
- Battery Management System harness diagnostics
- 100BASE-T1 and 1000BASE-T1 testing
- High-speed automotive Ethernet development
- 10GBASE-T1 harness fault location
- End-of-line cable harness QA
5G & Telecommunications

5G networks place increasingly stringent demands on antenna feeds, jumpers, RF interconnects and associated cabling. Testing these components only at low frequencies can fail to reveal performance issues that become significant at their actual operating frequencies.
With measurement capability extending to 26.5 GHz, technicians can verify high-frequency cable and antenna-feed performance closer to operating conditions and perform testing directly in the field rather than removing assemblies and sending them to a laboratory. This can help shorten installation, commissioning and troubleshooting cycles.
Typical applications include:
- 5G antenna feed verification
- RF jumper and feeder cable testing
- mmWave interconnect validation
- Field fault diagnosis
- Installation and commissioning
- Remote infrastructure monitoring
Aerospace & Defence

Aerospace and defence systems rely extensively on RF interconnects that must maintain tightly controlled insertion loss, return loss and impedance performance across wide frequency ranges.
The handheld TestPro platform allows these measurements to be taken closer to the aircraft, system or installation being tested. This makes the adapter suitable for depot-level maintenance, field verification and troubleshooting where transporting equipment back to a dedicated RF laboratory may be impractical.
Typical applications include:
- Avionics RF interconnect validation
- High-frequency cable assembly QA
- Depot maintenance
- Field diagnostics
- Defence communications systems
- RF connector and harness characterisation
Manufacturing & EMS

High-volume production environments need more than accurate measurement. They also require repeatability, clear acceptance criteria, throughput and traceability.
The adapter supports configurable PASS/FAIL limits, multiple harness profiles and IP-addressable connectivity, allowing it to become part of repeatable end-of-line test workflows. TestData Pro integration provides centralised result management, helping manufacturers build auditable records of every test performed.
Typical applications include:
- End-of-line cable harness testing
- Connector assembly QA
- Automated S-parameter testing
- Production PASS/FAIL validation
- Multi-site manufacturing test
- Centralised test-data collection
R&D & Test Laboratories

Development engineers working on high-speed differential pairs, RF interconnects and next-generation communication systems need detailed visibility into both frequency-domain and time-domain behaviour.
The adapter combines full 2-port S-parameter analysis with high-resolution TDR in a portable platform, allowing engineers to move easily between laboratory development, prototype debugging and in-situ validation.
Typical applications include:
- High-speed differential-pair development
- RF cable and connector characterisation
- Prototype debugging
- S-parameter analysis
- Impedance discontinuity investigation
- Bench and in-situ validation
