Bluetooth is an open specification for short-range wireless voice and data communications and forecasts estimate hundreds of millions of Bluetooth products will be sold annually by 2003. Bluetooth wireless interfaces present a new challenge to many manufacturers. The combination of leading-edge RF and protocol technologies, coupled with the requirement to get implementation costs down to a few dollars, put particularly high demands on he test environment. The challenge is to develop test procedures that are comprehensive in terms of both RF and functional test, but which are fast and initiated through a simple user interface.
Anritsu has met this challenge with the development of the MT8850A Bluetooth Test Set. Bluetooth developers can be assured of the quality of the measurements made with the MT8850A because it utilizes Anritsu's RF measurement technology.
All in-channel measurements required during production can be made with the MT8850A. The Bluetooth test Set can analyze RF power, frequency, modulation, and receiver sensitivity (BER/FER). In addition to conducting standard measurements according to the Bluetooth specification, the MT8850A can be configured to run custom test scripts. It provides full user control of a variety of test parameters including test frequency, frequency hopping ON or OFF, and the number of measured bits/packets looped back in a test.
All measurement can be pre-programmed into the MT8850A, so they can be conducted with a single keystroke for easy operation on the benchtop. A GPIB interface is available for programming in a manufacturing environment. Both GPIB and RS232 interfaces are standard on the MT8850A. Anritsu also has developed BlueSuite support software for advanced design on Bluetooth radios. BlueSuite allows burst power profiles, modulation eye diagrams, and graphs of all 79 frequencies' output power to be viewed on a PC.
The MT8850A allows measurements to be made quickly, making it an excellent tool for production test of Bluetooth chip sets and modules, as well as consumer products utilizing Bluetooth radios. In the cellular radio test environment, the MT8850A is an ideal complement. The Bluetooth tester can operate alone or in conjunction with a cellular handset tester to verify the performance of both the Bluetooth and digital cellular radio interface, while adding no incremental test time to the cellular radio production.
