Spirent Gets CTIA Authorization for Testing Mobile Devices


Spirent channel emulators help manufacturers and operators deliver higher data rates and better Quality of Experience (QoE)

Testing and measurement firm Spirent Communications today said it has been included in the list of MIMO Authorized Equipment List for CTIA’s Test Plan for 2×2 Downlink MIMO and Transmit Diversity over-the-air performance, version 1.1.

The CTIA Test Plan focuses on evaluating the performance characteristics of wireless Multiple-Input-Multiple-Output (MIMO) devices, which are highly prevalent in LTE networks and increasingly important as the industry moves toward 5G. Release of the Equipment List is the next step in preparing global test labs to obtain CTIA certification, a crucial part of the process toward mandating the new standard.

Over-the Air (OTA) testing is essential for MIMO devices because throughput, and therefore Quality of Experience (QoE), depends on antenna performance in realistic propagation environments. MIMO OTA offers several advantages vs. traditional cable testing by providing a more complete view of device performance, accounting for additional factors such as physical housing and nearby components. As antenna counts grow, it also becomes increasingly unwieldy to use cabled test setups. MIMO OTA creates a unique spatial signature to replicate realistic propagation scenarios in a controlled environment for comprehensive performance testing. The CTIA Test Plan recommends the test methodologies necessary to achieve this environment and the performance indicators for key characteristics such as antenna efficiency, branch imbalance, and correlation between antennas.

Spirent’s channel emulators are part of the CTIA-authorized solution along with the ETS-Lindgren anechoic chamber.

“ETS-Lindgren’s multi probe anechoic chamber works hand-in-hand with Spirent’s MIMO OTA channel emulators to address the requirements necessary for the CTIA MIMO OTA Test Plan. With this combined solution in place, global test labs can support device manufacturers and operators with a CTIA approved test methodology to ensure a superior QoE for their wireless MIMO devices,” said Roger Hatch, senior director for Solutions Development at ETS-Lindgren.

Rob Van Brunt, general manager for Spirent Communications’ Connected Devices business, which helped pioneer MIMO OTA testing during its inception in 2011, commented “Spirent has long supported MIMO OTA test implementations and continues to lead the industry with technology advancements such as the introduction of 4xN MIMO OTA testing. This is key as more chipset vendors and OEMs have been moving from two to four receive antennas in their devices. At the same time, we’re keeping a strong focus on features designed to simplify the testing process, such as our exclusive real-time fading engine, which allows users to dynamically alter test parameters mid-run vs. being tethered to rigid scripting. We’re pleased to achieve CTIA authorization for our Vertex and VR5 channel emulators and look forward to continuing our work with ETS to offer innovative OTA test solutions for 5G and other industry needs.”

Spirent is an industry-recognized leader across the entire span of OTA testing, with support for both A-GNSS and MIMO OTA test solutions and long-term partnerships with chamber manufacturers and test labs.

Keysight Unveils New Category Of Device Current Waveform Analyzer

Keysight – CX3300 Aanalyzer

Keysight-Unveils-New-Category-Of-Device-Current-Waveform-AnalyzerKeysight Technologies today introduced the world’s first analyzer enabling a minimum of 100 pA level dynamic current measurements with a maximum of 200 MHz bandwidth, 1 GSa/s sampling rate and 14- or 16-bit wide dynamic range.

The Keysight CX3300 Series Device Current Waveform Analyzer is a new category of instrument and is ideally suited for researchers struggling with high-speed transient current measurements during advanced device characterization and engineers working to reduce power/current consumption in low-power devices.

Characterizing advanced devices and evaluating low-power devices are challenging tasks; ones that require engineers to measure high-speed (over 1 MHz) and low-level dynamic current (below 1 μA). However, the existing methodology for this measurement is plagued by many issues – a large noise, voltage drop, limited dynamic range, bandwidth – and as a result, low-level dynamic current often goes undetected and unmeasured.

Keysight’s new CX3300 analyzer overcomes this limitation by enabling the simultaneous measurement of wideband and low-level current waveforms. By providing a 14-bit or 16-bit wide dynamic measurement range, a single instrument can meet a wide range of measurement requirements without using multiple instruments.

A graphical user interface on a WXGA 14.1” multi-touch display, and advanced measurement and analysis software, make previously difficult low-level current waveform measurements and analyses dramatically efficient and easier to make.

“Keysight’s new CX3300 Series analyzer stems from years of research and is in direct response to our customers’ needs for low-level dynamic current measurements without compromising wide bandwidth,” said Masaki Yamamoto, general manager of Keysight’s Wafer Test Solutions in Industrial Solutions Group.

“The CX3300, with its ability to measure wideband and low-level dynamic current, represents a significant breakthrough in meeting our customers’ needs. In addition to complementing the existing Keysight instrument portfolio, the new analyzer provides our customers with a more complete solution for device analysis,” added Yamamoto.

In addition to using the CX3300 analyzer to measure dynamic current, the analyzer can also be used as a debugging tool, enabling deep-dive and accurate evaluation during R&D. Doing so drastically increases R&D efficiency and accelerates the development process by shortening turn-around-time. Using the analyzer, engineers are able to write more aggressive power consumption specifications, and in turn, realize more confident power reduction.

The CX3300 analyzer consists of a mainframe with a WXGA 14.1” display and current sensors specifically dedicated to precision current waveform measurements. The mainframe features a 14-bit or 16-bit wide dynamic range, 200 MHz of maximum bandwidth, and a fast sampling rate of 1 GSa/s. The low noise and wideband current sensors support dynamic current measurements from 10 A down to 100 pA level.

Keysight’s new CX3300 Series Device Current Waveform Analyzer is available now. The mainframe price starts at $33,000 for the 2-channel model and $41,000 for the 4-channel model, with current sensors ranging from $4,800 to $6,900.

Anritsu-Submits-Thunderbolt-Receiver-Test-Solution-GRL-TBT3-RXAAnritsu submits Thunderbolt Receiver Test Solution GRL-TBT3-RXA calibration and receiver test software developed in cooperation with Granite River Labs (GRL).

The test solution is for use with Anritsu’s Signal Quality Analyzer MP1800A series at Thunderbolt Plugfest in Taiwan. The test solution supports calibration of the complex test signals required for evaluating Thunderbolt devices to lighten the workload of test engineers.

Data traffic is increasing explosively due to the spread of smartphones, mobile terminals and 4k video streaming. Achieving high-speed, large-capacity data transfers requires technologies for speeding-up networks and devices, as well as faster interfaces between high-end computers and peripherals. The receiver test for PHY devices using high-speed interfaces uses a stressed signal with added transmission loss, jitter, etc, to assure compatible connectivity.

The next-generation Thunderbolt 3 standard increases the bit rate per lane to 20.625 Gbps which requires even higher precision calibration and measurement.

Calibration of receiver test signals uses complex procedures to control multiple parameters, including Emphasis control of test signals, addition of multiple jitter types such as SJ, RJ, and SSC, and addition of common-mode noise, etc. Additionally, at device verification, it is important to control these functions within a specified range assuring good reproducibility.

Consequently, reducing the complexity of test signal calibration at receiver tests not only requires automated control in accordance with test specifications, but also requires measuring instruments with assured excellent reproducible performance for bit error rate measurements, low intrinsic jitter and noise, high input sensitivity, etc.

Anritsu and GRL are releasing this new solution to meet these test needs by automating complex test signal calibration.

This receiver test solution uses a combination of the MP1800A, noise-generating signal source, and real-time oscilloscope controlled by the GRL-TBT3-RXA software to lighten the workload of test engineers by automating calibration of complex test signals for jitter tolerance testing.

Additionally, the MP1800A is a wideband BERT with good performance including excellent waveform quality and input sensitivity, supporting not only high-reproducibility Thunderbolt receiver tests, but also evaluation of high-speed serial interfaces, such as 100GbE, InfiniBand, etc.

This new solution combining the GRL-TBT3-RXA software and MP1800A hardware simplifies receiver test calibration for jitter tolerance tests with good reproducibility to improve device evaluation efficiency.
