Designed to test systems used in the development and manufacturing of UE and Node B radio transmitters and sub-modules, using procedures defined in ETSI TS 134 121. Measurements include Channel Power (CHP) Adjacent Channel Power (ACP) QPSK Error Vector Measurement Peak and RMS (EVM) Occupied Bandwidth (OBW) Code Domain Power (CDP) Complimentary Cumulative Distribution function (CCDF).
The Vehicle Radio On-line Test System is capable of testing the vehicle radio system integrated with functions of FM/AM radios, CD player and cellular phone with hands-free capability. This system can measure the characteristic parameters and perform the comprehensive functional testing of the vehicle radio system on the production line.
The AM/FM toolkit takes full advantage of the impressive power offered by the latest dual-core Centrino processor when performing digital signal processing operations on the PXI controller. In normal conditions, the toolkit modulates single tone or .WAV audio files of AM or FM signals, then sends them to the PXI-5671 vector signal generator, where a 16-bit D/A converter provides an RF high quality signal.
Rather than using discrete electronics or DSP, the DARC toolkit takes advantage of the impressive power offered by the revolutionary dual-core Duo processor when performing digital signal processing operations on the PXI controller. The toolkit generates a composite signal: the FM signal is modulated by a single-tone audio signal, and the DARC signal is combined with the FM analog signal. The waveform samples are then sent to the PXI-5671 vector signal generator, where a 16 bits D/A converter provides a high quality RF signal.
The Digital Audio Broadcast (DAB) toolkit generates test signals from either stored pre-modulated waveform files or data streams known as Ensemble Transport Interface (ETI) files. The first option is called the manufacturing option, which is a waveform player that will play either a standard file from its library or a custom file specially designed to cover the requirements of a manufacturing test plan. The second option includes a software DAB modulator (ETI file player) that modulates the ETI files stored on the controller's hard disk.
Rather than using discrete electronics or DSP, the RDS toolkit takes advantage of the impressive power offered by the latest dual-core Centrino processor when performing digital signal processing operations on the PXI controller. The toolkit generates a composite signal: the FM signal is modulated by a single-tone audio, and the RDS signal is combined with the FM analog signal. The waveform samples are then sent to the PXI- 5671 vector signal generator, where a 16-bit D/A converter provides a high quality RF signal.
Satellite Digital Audio Radio Service (SDARS) toolkit generates test signals from data files provided by Sirius and XM, which are modulated in real-time by the URT. Both standards utilize a sophisticated transmission system involving a combination of satellites and terrestrial repeaters. Sirius broadcasts over three RF channels (SAT1, SAT2 and TERR), while XM's service has six channels (Sat1A, Sat2A, Terr. A, Sat1B, Sat2B and Terr. B) that are split over two ensembles ('A' and 'B') to reduce the complexity of the receivers.
The Traffic Message Channel (TMC) Software Toolkit frames are added to groups 3 and 8 of the RDS frames. The toolkit's software architecture easily allows the user to configure the most common parameters from switches or pull down menus. TMC parameters such as transmission characteristics, tuning information, single- or multi-group messages and the location’s encryption parameters can all be configured from the intuitive interface.
