CWT WLAN Bluetooth Signaling Tester 

The end-product signaling
test solution

CWT is an integrated one-box taster uniquely designed to test wireless equipments at the system level It provides an ideal test and measurement solution to achieve the test coverage of the entire end-product life cycle from R&D, QC through to manufacturing and post-sales service.

CWT supports WLAN/Bluetooth Network (Signaling) modes for testing wireless devices in conformance with IEEE 802.11x and Bluetooth 1.2, 2.0/2.1, 3.0+HS and 4.x specifications.

CWT’s compact design utilizes fan-less IPC and an optimized Ubuntu on SSD. The GUI (graphic user interface) is designed for an easy-to-configure operating environment. Automated testing is also supported. CWT is the ideal test solution for R&D and manufacturing.

IEEE 802.11x - WLAN

CWT Matrix-WLAN emulates WLAN network (i.e. signaling mode) for testing IP applications of Access Point or Station. With its attenuator module, CWT can simulate WLAN signal degradation wireless transmission with wide dynamic range of 90dB by 0.5dB step size. The bulit-in analyzer software offers test funcations including date throughput, Sensitivity Test, protocol analysis, connection status analysis (Handshake), and sniffer.

Bluetooth & AUDIO Testing

CWT Matrix-Bluetooth emulates Bluetooth signaling mode for testing Bluetooth devices in compliance with Bluetooth 1.2, 2.0, 2.1, 3.0+HS, 4.X and 5.x specifications. Various Bluetooth Profiles, such as HFP, A2DP, and AVRCP can be tested in a realistic environment. With Matrix-Audio TX/RX, Bluetooth devices’ audio and RF functions can be tested at the same time. Unlike conventional Bluetooth testers, CWT is uniquely designed for end-product testing including Infotainment system in the car, wearable devices, IoT devices and so on.
