Due to the steadily declining prices of Bluetooth chips, it is necessary to perform high-speed tests providing results in the form of a PASS/FAIL statement in the production of Bluetooth modules or their integration into headsets, mobile telephones, PCs or modems. The R4870 from Advantest makes it possible to measure the RF test cases described in the SIG standard at the press of a button. The tester can also be used to perform Blue Unit test cases, which are a quick means of obtaining information about a module’s communication capacity. Users can choose between either test method or perform both, of course. If, for example, one of the Blue Unit tests ends with FAIL, the cause can be determined by means of RF measurements. Furthermore, it is possible to optionally expand the R4870 into a small test system that covers all RF test cases and that can be used for making all prequalifying measurements.
