Test & Measurement: Azimuth supports VoLTE analytics

 Editor’s Note: The ability to test network and device features and functions is an important piece of technology development and deployment. RCR Wireless News looks weekly at the test and measurement space to see what’s afoot.
—Azimuth Systems had added Voice over LTE support to its Device-Network Analytics (DNA) and Device Automation and Control (DAC) integrated analytics and automation solution, which provides details on a per-call basis as well as aggregated analytics for VoLTE deployments.
–With its quarterly filings still in the midst of corrections since the departure of the company’s former CEO and CFO, Ixia received a notice from the Securities and Exchange Commission that it is out of compliance with NASDAQ listings standards. The company has been expecting the notice and appealed it, pushing the date for potential de-listing back to May 24 and asking that its stock remain listed until a hearing that has been scheduled for June 12.
“At the hearing, the company plans to present an updated plan to regain compliance with the rule and to request an extension of time for the filing of its delayed reports,” Ixia said.
—Tektronix launched its new BSA286CL BERTscope Bit Error Rate Tester this week, designed to handle the needs of testing for 100G communications.
—Ventev Wireless Infrastructure, which is a division of Tessco Technologies, showcased its new Terrawave Wireless LAN

site survey kit for Cisco indoor access points at Cisco Live this week in San Francisco. Terrawave is one of Ventev’s three product lines and a Cisco Solution Developer, and the new site survey kit (pictured at right) is designed to give systems engineers better insight into Wi-Fi deployment by including a variety of antennas and accessories necessary for an accurate assessment for coverage and capacity combinations.
—Agilent Technologies Inc. said that its EXM wireless test set for high-volume device manufacturing now supports 4×4 True MIMO for wireless LANs, with up to four TRXs testing MIMO antenna characteristics at the same time. The new features are designed to “support the design and validation characteristics of multiple antennas in mobile devices, access points, and WLAN adapters used in R&D and manufacturing environments,” the company said.
The EXM also has additional new features, including WLAN combined measurements for transmitter beamforming testing as part of device calibration testing, and independent source and analyzers for parallel receiver and transmitter testing, according to Agilent.
Other new features for the EXM include WLAN combined measurements that support transmitter beamforming test for device calibration testing, and independent source and analyzers for parallel receiver and transmitter testing to further speed up and optimize WLAN device manufacturing.
The EXM supports testing for 2G, 3G, LTE, LTE-Advanced and Wi-Fi connectivity, including the new 802.11ac standard.
Agilent also has a new automatic fixture removal (AFR) option for its PNA series of network analyzers, which used to only be available in its Physical Layer Test System (PLTS) software. Devices which do not have a coaxial connection are put in fixtures to be measured in a coax environment, Agilent noted, but the device-under-test can only be measured accurately if the fixture’s effects are properly removed. The new AFR option is designed to give engineers a faster, more accurate way to remove those effects.
