Keysight Technologies Inc. says it has gained Global Certification Forum (GCF) approval for 5G New Radio (NR) Non-Standalone (NSA) test cases, enabling the mobile ecosystem to accelerate protocol and radio frequency (RF) device certification. Keysight’s 5G Conformance Toolset, which supports both Protocol and RF/RRM, got GCF approval on January 16, 2019 at the recent Conformance […]
Test and Measurement Tips
New portable millimeter-wave measurement system spans 18–75+GHz
The new Ethertronics ETH-MMW-1000 Millimeter Measurement System is a compact, cost-effective, extremely accurate, and easily adaptable portable solution for testing 5G antennas and other devices at millimeter wave (mmWave) frequencies. Suitable for all mmWave system development and validation — including 5G communications, telecom industry research and development, university research, and other mobile communications and mmWave […]
High-performance programmable 2-channel 40-240-MHz function/arbitrary generators create complex low-distortion waveforms
The AIM-TTi TGF4000 Series dual-channel arbitrary waveform generators include models to 240 MHz offering exceptionally low harmonic distortion and phase noise. The TGF4000 series features an audio-band total harmonic distortion of just 0.05%. The TGF4000’s pulse generator design provides an exceptional pulse width resolution of 100 psec over a period range from 10 nses to […]
World-first GCF validation for 5G NR protocol conformance tests
The Global Certification Forum (GCF) has approved the world’s first 5G NR Protocol Conformance tests on the Anritsu 5G NR Mobile Device Test Platform ME7834NR at its January 2019 CAG57 meeting. The 3GPP TS 38.523-defined 5G tests have been validated on multiple millimeter wave (mmWave) (FR2) frequency bands. The ME7834NR is registered with both the […]
5G NR network emulation setup verifies maximum data throughput rates
Keysight Technologies Inc. says it has demonstrated maximum achievable 5G New Radio (NR) data throughput performance using the company’s 5G NR network emulation solution, which is based on Keysight’s UXM 5G Wireless Test Platform, and Samsung’s 5G NR Exynos Modem 5100. Keysight says this development will help accelerate 5G enhanced mobile broadband (eMBB) applications. It […]
Verizon Cutting About 800 Jobs in Troubled Media Business
Verizon is cutting about 800 jobs, or 7 percent of its media and advertising employees, as it reorganizes the troubled division. The wireless company had hoped to create an ad business that could compete with Google and Facebook. It spent roughly $10 billion buying up former Internet pioneers Yahoo and AOL . But Verizon found […]
The difference between histograms and spectrograms
Despite their similar names, histograms and spectrograms are totally different ways of displaying a signal or function in a digital storage oscilloscope (DSO). Both are useful in organizing and analyzing electrical waveforms, but the type of information that is displayed and the conclusions that may be drawn from them are worlds apart. Histograms and spectrograms […]
New power rail probes solve key measurement challenges
The TPR1000 and TPR4000 power rail probes combine with the 12-bit 5 or 6 Series MSO mixed signal oscilloscopes from Tektronix to offer what’s said to be the lowest system noise of any power-rail measurement solution available in the market today. The new probes are backed by a complete set of connectors for small, difficult-to-access […]
T&M pioneers among lastest group of Inventor Hall of Fame inductees
The latest group of nineteen inductees making up the 2019 Class of the National Inventors Hall of Fame include two pioneers in the test and measurement field. Inductees Jeff Kodosky and James Truchard introduced LabVIEW in 1986 as a graphical programming language that enables user-defined testing and measurement and control systems. It grew to be […]
Difference between synchronous and asynchronous (induction) motors
All rotary electric motors, ac and dc, operate because of the interaction of two magnetic fields. One is stationary and is (usually) associated with the motor’s outer enclosure. The other rotates and is associated with the motor’s spinning armature (also called its rotor). These two fields are created by interactions between magnetic fields. In a […]
