Modular and scalable systems for radiomonitoring Compact digital broadband direction finders: extremely fast and highly precise Comprehensive monitoring of MPEG-2 transport streams 2 The focus of this issue is radiomonitoring: The latest generation of the R&S ® RAMON product family – systems for radiomonitoring and communications intelligence – is presented on page 39. The broadband Direction Finders R&S DDF ® 0xA unite top-class RF engineering and the fastest digital signal processing components (page 44). With the help of the Shielded RF Test Fixture R&S ® TS7110, users can implement individual test requirements in no time at all without facing the risks of new developments. And the best news first: The fixture can accommodate completely different tests, from initial board tests to complex final tests (function tests). FIG 1 Test fixture (open) for PCB and final tests. The R&S ® TS7110 (FIGs 1 and 2) is a shielded test fixture for UUTs with a radio interface, such as mobile phones, personal digital assistants (PDA), remote keyless entry, wireless phones, etc. The UUTs can operate on the basis of diverse radio standards such as GSM, WCDMA (UMTS), Bluetooth™*, WLAN or Home RF. The fixture was designed for the R&S ® TS7100 (cPCI) and R&S ® TS7180 (PC-based) production test systems [1] [2]. However, owing to its standardized USB interface and modular design, it can also be used in combination with other test systems. A DLL interface is provided on the software end to control the individual components. The fixture is primarily used in production , but also in service, repair and quality assurance. * The Bluetooth word mark and logos are owned by the Bluetooth SIG, Inc. and any use of such marks by Rohde & Schwarz is under license. The semi-automatic R&S ® TS7110 test fixture consists of a base and a fold-out upper part with pneumatic support for easier opening and closing (FIGs 1 and 2). The upper part includes a universal stabilizing piece for UUT positioning as well as other test fixtures for tasks that need to be performed from the upper side of the UUT (FIGs 3 and 4). The base integrates the lower part of the RF chamber with the exchangeable test fixture including UUT mount. The test system interface is also fitted here, containing fixture control as well as additional built-ins, signal conditioning and level converters for communication with the UUT. Mechanically standardized interfaces make it …
