Headphone RF Test System

Electroacoustic Test

Measurement in ACL/DUT mode is supported to meet RF of different products.

Basic Rate and EDR measurement performed in Bluetooth test mode supported.

The test is fast and stable which finishes within 8-10s

Overview

The constant issues of slow pairing, frequent disconnection, and stuttering in music and calls are among the most significant factors affecting the user experience of TWS headphone. To prevent products with communication problems from reaching consumers and to continuously improve the communication performance of products, CRYSOUND provides a duplex RF test system solution in dual shell-shaped shielding chamber.

Features

Compatibility

‍The solution supports platforms such as Qualcomm/CSR, BES, Realtek, Vimicro , Broadcom, Bluetrum, and JL ,also,the solution is compatible with Anritsu MT8852B, Agilent N4010A, and R&S CMW500 Bluetooth communication analyzers, providing customers with diverse options. The solution supports ACL or DUT test mode to satisfy the RF test needs of different products as well.

Efficiency

‍The solution is designed for two workstations share one instrument, allowing the operator to run both workstations at the same time, thus maximizing the efficiency of the expensive RF equipment.

Customerized

‍The RF test fixtures are designed strictly according to RF testing requirements, allowing for quick switching between PCBA and finished product testing by simply replacing the fixture.Our software is self-developed, providing software customization services, and supporting integration with MES.

CRY591L Bluetooth Switch Matrix

The CRY591L is our latest RF switch matrix, designed specifically for RF characterization testing of Bluetooth® headset PCBAs. It boasts exceptional RF performance and high stability, making it perfect for both research and development and production environments. This versatile switch matrix acts as a dynamic interconnection hub between test equipment—such as network analyzers, spectrum analyzers, Bluetooth testers, signal sources, receivers, and devices under test (DUTs)—enabling RF signals to be routed through multiple configurable paths.

CRY710 Pneumatic Acoustic Test Chamber

The CRY710 Pneumatic Shielding Box, constructed from welded steel plates, provides robust RF shielding for testing Bluetooth, Wi-Fi, and other devices, effectively preventing interference between production lines. It also offers a soundproof environment for assessing acoustic performance. The pneumatic door can be controlled via the serial port.

‍For quadruplex audio testing of TWS headphones, combining two CRY710 boxes with a CRY6151B enables a single operator to manage two test stations simultaneously, significantly reducing labor costs.
