R&S®TS8975 Mobile WiMAX™ RF Preconformance Test System RX/TX RF tester
12.05.2009 08:09:04
R&S®TS8975 Mobile WiMAX™ RF Preconformance Test System At a glance The R&S®TS8975 is the ideal RX/TX RF tester in R & D, quality assurance and precompliance when it comes to the testing of mobile stations in line with the Mobile WiMAX™ test specification.
The R&S®TS8975 enables high-precision RF characterization of Mobile WiMAX™ mobile stations in line with the WiMAX™ Mobile Radio Conformance Test specification. In many aspects, the system is similar to the highly successful R&S®TS8970 used by many of the WiMAX Forum® Designated Certification Labs (WFDCL). The test cases offered for Mobile WiMAX™ mobile stations (MS) are traceable to those provided on the R&S®TS8970 and follow the MRCT V2.2.1 (Mobile WiMAX™ Radio Conformance Test) specification. Unlike on the R&S®TS8970, the test cases on the R&S®TS8975 are not periodically revalidated, yielding significant cost savings for customers. Many test engineers are already familiar with the R&S®PASS user interface because an identical form of it is implemented in the widely used R&S®TS8950 certification system for GSM/WCDMA and in the R&S®TS8970 for Mobile WiMAX™. Key facts J Frequency range from 2 GHz up to 6 GHz (optional: from 400 kHz), enabling customers to test all band class profiles defined by the WiMAX Forum® as well as future profiles J Based on the R&S®CMW270, which allows a multitude of debugging features and more flexibility than earlier pre-RCT systems J Scalable from the compact two-box benchtop setup up to the 19" rack system, the R&S®TS8975 can be expanded to meet increasing test depth requirements J Even in the system's basic configuration, approx. 60 % of the MS MRCT V2.2.1 test cases are covered J High measurement accuracy due to full path compensation yields more reliable results than can be obtained by standard lab setups J Very detailed measurement reporting that corresponds to the R&S®TS8970 RCT output

R&S®TS8975 Mobile WiMAX™ RF Preconformance Test System Benefits and key features Cost-effective solution for R & D, quality assurance and precompliance testing on Mobile WiMAX™ mobile stations JJ The R&S®TS8975 WiMAX precertification system enables realistic mobile station tests in full signaling mode JJ The instruments used in the system require calibration only every 24 months. Between calibrations, the integrated path compensation (optional: automatic path calibration) functionality ensures optimum measurement accuracy JJ The use of digital baseband connections for generating interferers and channel emulation reduces RF switching as well as possible RF interference effects JJ High-speed self-test mechanisms deliver maximum accuracy and reproducibility of measurement results JJ Fully automated regression test sequences for unattended execution of all tests including those under extreme temperature and operating voltage conditions
Strong support for achieving RCT first time pass necessary test methods traceable to WiMAX Forum® CWG radio conformance test platform RCT 11 JJ Test methods approved and kept up to date at regular intervals JJ Individual or sequential execution of tests possible JJ All
Automated data logging, report generation and user‑configurable PASS/FAIL output JJ Full access to measurement result output JJ All PASS/FAIL criteria can be edited JJ Graphical output of measurement results versus tolerance criteria JJ Easy evaluation of test results Scalable future-safe test platform with a compact benchtop configuration using any existing instruments from Rohde & Schwarz (see page 7 for d etails) JJ Basic platform can be upgraded from a compact benchtop set-up with channel emulation up to a full R&S®TS8975 rack configuration with extended test case coverage supporting the simulation of 2x2 MIMO scenarios as specified in the MRCT specification JJ Can be upgraded to the R&S®TS8970 radio conformance test system with full test case coverage JJ Can be upgraded to the R&S®TS8980 LTE RF test system JJ Start
R&S®PASS validated conformance test platform software JJ Same test methods and test sequencer as in the validated R&S®TS8970 RCT JJ User access to test sequencing, application and logical device layers JJ Parametric tests for many of the MRCT test items JJ Individual definition of tests by parameters allows user defined test steps to be built JJ Efficient test and analysis tools accessible directly in the graphical user interface (GUI) JJ Due to a common application platform, continuous improvements to the R&S®TS8970 in line with the evolution of the standard are also available on the R&S®TS8975 JJ Any R&S®TS8975 configuration can be expanded to create the validated R&S®TS8970 type approval system if full validated test coverage is desired later

The R&S®TS8975 combines the characteristics of market-leading Rohde & Schwarz products Depending on the configuration, the R&S®TS8975 Mobile WiMAX™ RF preconformance test system combines the characteristics of the following market-leading products from Rohde & Schwarz:
R&S®CMW270 WiMAX™ communication tester The R&S®CMW270 WiMAX™ communication tester functions as a signal source for all MS tests, and performs all RX tests and some of the TX measurements. An optional message analyzer tool allows the detailed analysis of message content and burst structure. The tester is available with or without SVGA display. R&S®FSG or R&S®FSQ vector signal and spectrum analyzer The R&S®FSG and R&S®FSQ vector signal analyzers combine essential characteristics of the R&S®FMU vector signal analyzer and of the industry reference for spectrum analysis, the R&S®FSU, in one unit. In the R&S®TS8975, the R&S®FSG/FSQ handles the majority of the RF transmitter measurements. R&S®NRP power meter The R&S®NRP power meter is the first product of its kind that incorporates all measurement functionality in the sensor itself, i.e. it does not require a base unit. It serves as the R&S®TS8975 RF level reference and is used in the system's level and path calibration process as well as its automated sanity check procedure if R&S®ISSCU-2x2 is installed. Expansions available for the R&S®TS8975 R&S®AMU200A baseband generator The R&S®AMU200A baseband signal generator and fading simulator combines versatile realtime I/Q sources and a cost-effective multichannel fading simulator in one box. One or two of these instruments can be used to generate wanted and interfering signals, superimposed noise, and standard-compliant channel emulation. Switching units The components of the system and the DUT can be equipped with the favorably priced passive R&S®CS8980MST cable set. Optionally, they may be interconnected using the R&S®TS-EX-IQ2 baseband switching unit and/or the R&S®ISSCU-2x2 RF switching unit. Connections to the R&S®NRP and the DUT are then also included to enable fully automated level compensation routines. It is recommended to exercise great care when setting up a MIMO benchtop configuration. Increased convenience as well as protection from wiring errors may be obtained by including the R&S®ISSCU-2x2 in a rack configuration.
Rear view of the R&S®OSP with three module slots and Ethernet interface for direct connection to a PC or for integration into an Ethernet network.
Multi-DUT regression testing The R&S®OSP can be used for multi-DUT applications or may be added to the R&S®TS8975 for general RF switching and control tasks.

Max. R&S®TS8975 output level depends on the chosen carrier center frequency and on whether a passive cable or the R&S®ISSCU-2x2 switching unit with built-in amplification is used. 2) For carrier center frequencies up to 2.7 GHz, the R&S®TS8975 provides a fully compliant output level. 3) AMC, ACK/NACK and CRC are mandatory only in the Wave 2 version of these test cases. These properties may be set to active if the R&S®TS8975MS2 option is installed on the R&S®TS8975. 1)
