Bluetooth tester

Wednesday, 28 April, 2004

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

The tester is made up of two main blocks, an 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 RS232C, USB, PCMCIA, LAN and other standard peripheral devices. The adoption of an open OS minimises unnecessary constraints on system optimisation. This system architecture takes advantage of both the power of DSP and the convenience of a PC.

The device 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.

It is also 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.
