Automated test tool for navigation devices A
new automation and reporting tool from Spirent
Communications reduces the cost and testing times associated with the characterization of global navigation satellite system (GNSS) devices. TestDrive-GNSS provides a
suite of test cases that enables fundamental characterization tests to be performed in an
automated and controlled way. Examples of fundamental characterization tests include time-to-fi rst-fi x (TTFF), acquisition sensitivity, tracking sensitivity, re- acquisition time, and static and dynamic navigation accuracy. The tool also provides a formal test report at the end of the process. Characterization tests can be cumbersome to execute
manually, especially when iterative repetition is required as test signals and conditions are changed. “TestDrive-GNSS unlocks the
full power of a Spirent GNSS simulation system, enabling the test equipment to do the work with minimal intervention”, said Stuart Smith, product manager for Spirent’s navigation and

CMW500 wideband radio communication tester. T is multi-standard platform performs RF, protocol, performance and application tests on wireless devices for LTE (FDD and TDD), WCDMA, HSPA+, GSM and CDMA2000. It can also test the handover between these technologies. One major application for this tester, R&S explains, is the rollout of
Probing within the test chamber: Teseq’s new battery-powered EMC signal analyser module communicates with the outside world via a fi bre cable and a high-speed optical interface
Tripling the range of EMC test system T
EMC/EMI receiver module which extends the frequency range of its PMM 9010 receiver system from 6 GHz to 18 GHz. Designed for use in commercial test labs and in manufacturers’ own test facilities, the upgraded PMM system can now be used for a wider range of EMC testing. According to the manufacturer, the PMM 9180 module offers high
performance, convenience and cost savings through cutting turn- round times and eliminating the need for expensive coaxial cables and periodic calibration checks. The unit is also claimed to provide better radiated emissions system sensitivity than others on the market. The battery-powered signal analyser is said to be the only fully-
compliant EMI receiver module directly connected to an antenna located inside the testing chamber. It has the ability to transmit data outside the testing chamber via optical fi bre cable, eliminating signal losses that can exceed 20 dB. The FCC requires that EMC emissions testing be performed at ten
times the highest clock frequency in a product. With the PMM 9180, FCC testing can be performed on products with clock speeds to 1·8 GHz as well as MIL 461 RE 102 testing, which has an upper frequency limit of 18 GHz. The PMM 9180 can also be used for CE marking.

eseq, which supplies instrumentation and systems for EMC emission and immunity testing, has introduced a high-performance digital
voice services in LTE networks. To support these services, wireless de- vices will use the new Voice over LTE (VoLTE) technology. To help network operators and manu- facturers of wireless devices meet this challenge, Rohde & Schwarz off ers a test solution based on the CMW500 and the UPV audio analyser, which allows signalling and audio quality tests for VoLTE. A new test package for WLAN-RF and end-to-end data testing on wireless devices is also available. • An updated version of R&S’s drive-test solution allows network

mong the test equipment to be featured by Rohde & Schwarz at next month’s Mobile World Congress in Barcelona will be the
positioning division. “It not only saves time, but helps to increase test quality and accountability with its comprehensive test reporting. With TestDrive-GNSS, fundamental GNSS receiver characterization has just become a much easier, more effi cient process.”
The CMW500 wideband radio communication tester from Rohde & Schwarz – a powerful multi-standard platform
operators and infrastructure manufacturers to perform MIMO-specifi c measurements in LTE networks. T e data it gathers helps to determine where MIMO functions best in a specifi c coverage area and where investments in MIMO pay off . With the new software, the R&S TSMW drive test scanner supports not only LTE, but also previous standards such as UMTS and GSM. It covers all bands from 30 MHz to 6 GHz. •

Portable tools for testing LTE E
nhanced versions of Anritsu’s MT8212E/MT8213E
Cell Master and MS2712E/ MS2713E Spectrum Master handheld analysers have new measurement capabilities and improved overall performance to address the rollout of 4G technologies, including TD-LTE. Offering superior performance
in a compact design, these instruments offer service
providers, manufacturers and installers a cost-effi cient and accurate test tool for deploying and maintaining LTE networks. Anritsu describes the new
Cell Master models as the smallest, lightest, and most economical solution for base station testing during installation commissioning, maintenance and troubleshooting. •
