Tescom TC-3000A Bluetooth Tester

TESCOM TC-3000A Bluetooth Tester eliminates the need for several costly testers by combining key RF and Protocol test & measurement functions in one convenient box. Designed for a wide range of applications in R&D, manufacturing, QA and service, this feature-packed powerful instrument is simple to use, lightweight and portable, and may be operated with all standard AC voltages. In addition to Bluetooth testing applications, TC-3000A may be used for non-Bluetooth RF testing along the 2.4GHz ISM band.


System Architecture:
TC-3000A is made up of two main blocks, a RF/DSP module and a host CPU module, and is connected by a host controller interface (HCI) that is identical to Bluetooth system architecture. The RF/DSP module provides an RF interface to DUT, performs physical measurements and manages the Bluetooth link. The internal host CPU (PC), which runs on a Linux platform, takes care of user interface (UI) functions including display, key input and I/O controls for RS-232C, USB, PCMCIA, LAN and other standard peripheral devices. The adoption of an open OS minimizes unnecessary constraints on system optimization. This simple, elegant system architecture takes advantage of both the power of DSP and the convenience of a PC.

Custom Protocol Stack:
The TC-3000A Bluetooth protocol stack has been developed with in-house technology in order to gain total control of the performance and feature set of the tester. Its unique protocol stack architecture positions ¡®queues¡¯ between protocol layers, making it conceptually simple and easy to apply. This approach helps guarantee the system¡¯s long-term supportability, while efficiently handling future customization and enhancement requirements.

Versatility of TC-3000A:
TC-3000A can interface with DUT through most known HCI interfaces. Additionally, the RF/DSP module can relinquish control to an external PC through standard HCI, allowing for an emulated Bluetooth development environment. Remote connection through TCP/IP allows the efficient control of multiple testers from a PC located practically anywhere in the world.

Speed test mode:
It is essential to minimize the test time in manufacturing. TC-3000A is capable of skipping the time-consuming INQUIRY procedure by reading the Bluetooth device (BD) address directly through HCI. Test configurations can be edited to reduce the number and time of tests.

Bluetooth Test Platform

TC-3000A combined with a TESCOM quality test fixture provides predictable RF coupling and shielding performance, to offer an economical, quality Bluetooth test platform for production, service or R&D environments.

Since most Bluetooth devices use sealed antenna due to their size, final RF tests must be done over the air (OTA). In case of module or PCB testing, contact probes may also be used. In either case, testing must be completed under an adequately RF isolated condition with reliable RF coupling. A simple isolation box that disregards internal resonance and shielding qualification will result in unreliable RF test data. All TESCOM isolation boxes are designed to minimize this problem. In practice, OTA coupling over a wide frequency band exhibits some level of frequency slope due to antenna bandwidth or cable connector reflections. This channel-dependent residual slope may need calibration to guarantee the accuracy of TX power measurement.

TEM Cell TC-5060A/B

TEM Cell is a broadband radiation test cell that provides both high isolation and predictable RF coupling. The total coupling loss through typical DUT antenna to TEM Cell output is around 30dB at Bluetooth frequencies. With the additional filtered data port and power lines, the desktop-size TC-5060A/B offers an ideal radiation test platform for small RF devices, such as Bluetooth devices.

Shield Box

TESCOM's popular absorber-lined Shield Boxes are widely used for RF test fixtures in R&D, service or manufacturing worldwide. These manual or pneumatic boxes with device fixtures can handle many different types of devices, such as PC assemblies, RF modules or final products. Various RF signal connection methods, such as probe heads, OTA couplers or special connectors, can also be supplied by TESCOM. Most units also include the pneumatic operation option, which relieves operator fatigue in manufacturing. High isolation and the absence of in-band resonance in every TESCOM boxes improve test repeatability.
