Moveable Over-the-Air Test Chamber for 5G
Rohde & Schwarz offers the first moveable over-the-air test chamber for 5G antennas and transceivers. With the new R&S ATS1000 all-in-one antenna test system, active and passive antennas as well as transceivers for future fifth generation (5G) mobile networks can be tested in a compact, moveable shielded RF test chamber. This enables far-field antenna characterizations and initial RF measurements for 3GPP 5G NR in the millimeter wavelength range.
The new R&S ATS1000 antenna test chamber allows developers and production engineers to perform over-the-air (OTA) measurements for 5G on their antenna modules, transceivers, chipsets and wireless devices. Antenna and transceiver measurements are possible in the frequency range from 18 GHz to 87 GHz. The system therefore supports all millimeter-wave frequency bands currently considered for 5G. The compact test chamber makes it possible to measure mobile devices in the far field.
The R&S ATS1000 consists of a rack-sized shielded RF test chamber on castors, suitable mounts for test objects and sensors, and a wideband measurement antenna, which covers the whole frequency range. Using the associated test and measurement equipment and the R&S AMS32 antenna measurement software, radiation patterns of 5G antenna arrays can be measured with extreme precision in just a few minutes. A positioning laser supports precise orientation of the test object.
By combining the R&S ATS1000 with an R&S TS8980 5G RF test system, users can determine relevant RF parameters (e.g. power, ACLR and EVM) from OTA measurements. This is crucial because many 5G components do not have any connectors and therefore cannot be tested in conducted setups. The system enables comprehensive 3D characterization, verification measurements and functional testing of 5G components. Rohde & Schwarz conformation test solutions use the well-established R&S CONTEST software to output results in the form of 3D graphics.
For automated, final functional testing, the R&S AMS32 software allows users to control the R&S ATS1000 remotely. It also generates configurable reports for documentation. The solution additionally offers near-field/far-field transformation for larger test objects.

Multi-device Synchronization for Lock-in Amplifiers and Arbitrary Wave Generators
Zurich Instruments Lock-in Amplifiers and Arbitrary Wave Generators (AWG) can now be synchronized thanks to the new Multi-Device Synchronization function (MDS). This allows multiple instruments to be connected together and controlled on one user-friendly interface. The MDS takes care of the synchronization of both the 10 MHz clock and the sampling rates of each connected instrument. Instead of using one multi-channel instrument, single instruments can be added as required and subsequently synchronized as one. This increases the flexibility and scalability of existing measurement systems.
The included LabOne software allows measurements to be taken simultaneously on multiple instruments. Datapoints taken at the same time are labelled with the corresponding timestamp, allowing the datapoints to be clearly assigned and analyzed. Furthermore, LabOne offers a wide range of integrated tools for signal analysis, reducing the complexity of the experimental setup (Lock-in Amplifier, Sweeper, Signal Generator, Oscilloscope, FFT-Spectrum Analyzer, Spectroscope, Digitizer). Existing customers of Zurich Instruments can also add MDS functionality free of charge by updating LabOne to version 17.12.
Multi-device Synchronization is especially interesting when building prototype quantum computing setups, as the number of signal channels can be easily and reliably scaled up. Further applications include quantum transport measurements where, for example, Hall resistance and electrical resistance are measured simultaneously. In synchrotron applications such as beam position monitoring, MDS facilitates multi-axis measurements.

All-In-One Solution for EMI/EMC Compliance Testing
Tektronix has introduced EMCVu, a new all-in-one solution for EMI/EMC pre-compliance testing and troubleshooting. In today's electronic design environment, about 50 percent of products fail electromagnetic compatibility (EMC) testing the first time. EMCVu gives engineers an accurate, convenient and cost-effective approach to determine if their product designs will pass EMC emission compliance testing on the first try.
With the arrival of Internet of Things (IoT) and a proliferation of electronic devices that can interfere with each other, designing products to meet EMC emission requirements is critical. For many engineers just starting work on new IoT devices, EMI/EMC testing can be intimidating, and failing compliance testing leads to significant cost overruns and schedule delays. Pre-compliance testing reduces failure rates, but introduces its own challenges including difficult & expensive equipment set up, testing accuracy, painful debugging, and a lack of reporting tools.
At the core of the new solution are the Tektronix real-time USB spectrum analyzers, including the affordable RSA306B, that offer the performance of traditional desktop instruments at a fraction of the cost. Powered through the USB connection, the small size of Tektronix' real-time USB spectrum analyzers makes it easy to perform EMI/EMC testing outside the lab environment in relatively low-noise environments, such as basements or parking garages.
The instruments are controlled by SignalVu-PC software running on a laptop or tablet. For this application, SignalVu-PC has been enhanced with optional EMCVu software to provide pre-compliance and troubleshooting capability in the same user Interface.
The spectrum analyzer and software are complemented with a comprehensive set of accessories that have all been carefully selected and thoroughly evaluated to maximize test efficiency. To ensure accurate results and save time for users, the loss or gain of the various accessories has already been captured in the software and is accounted for during measurements.

Miniature Shock Accelerometers
PCB® has released two new miniature piezoelectric accelerometers. They are small, single axis ICP® voltage output with measurement ranges of +/- 5,000 g (model 352A91) and +/- 20,000 g (model 352A92). Both are in a similar package with low mass under 0.006 ounces (0.17 grams) and cover a broad frequency range of 1.2 to 10,000 Hz at +/- 5%. The accelerometer development concentrated on survivability under test in harsh environments. The hermetically sealed titanium housing and flexible cable design enable the sensor to survive high overload shock (+/- 20,000 g peak) under thermal load up to +325 °F (163 °C). These features make them ideal for small component testing, environmental stress screening, and impact testing of electronic board assemblies.
Built-in ICP® microelectronics provide a low noise, low impedance output signal for low transmission loss over long distances.

Advanced Terahertz Imaging Platform
Reacting to the growing demand in non-destructive testing applications, TOPTICA has further extended its terahertz instrumentation portfolio. This year the company presents a new terahertz Imaging Extension for its successful time-domain spectroscopy platform TeraFlash. Owing to the unique spectral bandwidth of the TeraFlash (0.1 – 5 THz), researchers can exploit the full potential that the combination of imaging and spectroscopic methods has to offer.
The Imaging Extension uses two precise linear stages to scan a sample through the focus of the terahertz beam. The translational movement is synchronized with the delay-stage within the TeraFlash, speeding up the measurements significantly, allowing the system to acquire complete waveforms for up to 16 pixels per second. The positioning accuracy is better than 200 µm over a 15 x 15 cm field of view.
Co-developed with experts from Fraunhofer Heinrich Hertz Institute (Berlin, Germany), the Imaging Extension comes in two versions – a “basic” setup for researchers who wish to use their own optical components, and a “complete” version that includes parabolic mirrors for beam shaping and focusing.
The Complete Imaging Extension offers a unique flexibility: With the help of alignment pins, users can quickly reconfigure the optics from a transmission setup to a reflection geometry and vice versa.
Both versions feature a powerful software package that offers a choice of contrast parameters including amplitude, phase and layer thickness.
