Testing

Collaborative research taking place between the Universities of Bristol and Lund, National Instruments and BT has set up field trials of a massive MIMO system working in a large indoor environment. The aim was to test massive MIMO spatial multiplexing indoors and improve the understanding of massive MIMO radio channels under mobile conditions with untethered devices. As a result of ...

Giovanni D’Amore discusses approaches to characterising both dielectric and magnetic materials using impedance analysers and specialist fixtures. We are used to thinking about technological progress in terms of mobile phone model generations, or semiconductor manufacturing process nodes. These provide a useful shorthand, but overshadow progress in enabling technologies, such as those in materials science. Anyone who has taken the back ...

TiePie Engineering of the Netherlands has introduced a 1Gsample/s four-channel PC oscilloscope with differential capability. Called Handyscope HS6 DIFF, is connects via USB 3.0 and is available in versions down to 50Msample/s. The firm has included what it calls ‘SafeGround‘ technology, claimed to prevent damage if inputs are switched from differential to single-ended without thinking. “SafeGround allows you to use the oscilloscope ...

Rohde & Schwarz’s latest oscilloscope launch at Embedded World in Nuremberg has 10-bit vertical resolution and a touchscreen. The benefit of the 10-bit analogue-to-digital converter (ADC) front end over the more traditional 8-bit ADC on this class of scope is that it provides 1024 vertical positions, which allow for more precise measurements. Prices start at €1,250 for the 2-channel 70 MHz model. The R&S RTB2000 oscilloscope has 10 Msample acquisition ...

Rohde & Schwarz and MediaTek collaborate on testing 5G: mm-waves for 5G radio access and over-the-air testing concepts for massive MIMO antenna arrays.

How your use of power sensors and spectrum analysers can influence outcomes in RF and microwave power measurements, writes Giovanni D’Amore of Keysight Technologies.

Rohde & Schwarz adds a 6GHz oscilloscope to its RTO2000 scope family, Intended for the testing of radio interfaces of 802.11ac WLAN components for IoT modules

PanaTeQ introduces a 3U (100 x 160mm) OpenVPX-compatible board with Xilinx 16nm Zynq UltraScale+ SoCs.

Rohde & Schwarz has introduced a video test system for high dynamic range HLG-capable video consumer devices. Hybrid Log-Gamma (HLG) is a royal-free standard jointly developed by broadcasters the BBC and NHK. The test system is based on the recently introduced module for HDMI and HDR tests, which is a generator and analyser for data rates up to 18Gbit/s as well as functions such as scrambling introduced ...

Future trends, technologies and engineers were the subjects for the keynote of NIDays 2016, National Instrument’s Graphical System Design Conference in London.
