RF · AUDIO · TEST ACCESSORIES
Make Every Connection Part of a Reliable Test
Test accuracy depends on more than instruments. Antennas, cables, connectors, adapters, probes and fixtures determine whether signals reach the DUT consistently.
We provide complete connection and fixture solutions for RF, microwave, wireless and audio testing, from standard accessory selection to custom test-tool design.
RF / Microwave Test Interconnect & Accessories
WHY ACCESSORIES MATTER
Instruments Matter, and Every Connection to the DUT Matters Too
In high-frequency testing, cable loss, connector mismatch, adapter count and fixture parasitics all enter the measurement path; in production testing, fixtures also affect takt time, repeatability and contact life。
Reduce Link Loss
Select cables for frequency, power, length and bend requirements.
Maintain Impedance Continuity
Configure interfaces and adapters to reduce reflection and mismatch.
Improve Test Repeatability
Positioning, compression and quick connections reduce operator variation.
Meet Production Takt
Balance performance, mating life, changeover and maintenance cost.

03 · RF FIXTURE / PROBE
RF Fixtures, Probes and DUT Interfaces
When a PCB, module or wireless terminal cannot connect directly to an instrument, fixtures adapt standard coaxial ports to the DUT while handling mechanical positioning, impedance continuity, parasitics, calibration and de-embedding。

- RF Test Probe
- Coax-to-PCB Transition
- Quick Compression and Positioning
- Calibration Structure
- Fixture De-embedding
AUDIO & ACOUSTIC FIXTURE
Audio Testing Also Requires the Right Fixtures and Coupling
For headphone, TWS, speaker and microphone testing, positioning, sealing, ear simulators, measurement microphones and fixture repeatability all affect results。

CUSTOM ENGINEERING
No Standard Product Interface? We Build the Test Interface
Many mass-produced products have no standard port for direct instrument connection. What is needed is an integrated design of a product-specific interface, mechanical fixture and automatic control。

A Good Fixture Turns Complex Testing into One Simple Operation
The value is not merely making a connection, but keeping repeated testing stable, fast and maintainable.
Custom RF Fixture / Production Test Interface
CASE EXAMPLE · WIRELESS MODULE
Wireless Module Production-Test Interfaces and Fixtures
For wireless modules that are unsuitable for repeated manual mating, we design DUT positioning, RF test points, quick-compression probes, low-loss cables and instrument-side adapters as one system。
Turn manual screw-on steps into a standard station flow: place the product, compress, test automatically, release and remove. Wear parts are designed as quick-maintenance modules。
- Stable RF Contact
- Reduce Connection Time
- Quick Replacement of Wear Parts
- Automation / MES Ready
