MIMO and beamforming provide increased data rates than you can get using single, omnidirectional signals. Antennas convert between radio waves propagating through space and electric currents moving in a metal conductor. In early communication system, antennas were often quite simple, perhaps just a half-wave dipole constructed of wire. We usually just had one antenna per…

Keysight Technologies acquires Eggplant
Keysight Technologies has acquired Eggplant from The Carlyle Group. Eggplant is a software test automation platform provider that uses artificial intelligence (AI) and analytics to automate test creation and test execution. Eggplant’s Digital Automation Intelligence platform can test any technology on any device, operating system or browser at any layer, from the user interface (UI) […]
Network analyzers incorporate high-performance signal generators for complex measurements
Enhanced PNA and PNA-X network analyzers contain a proprietary low-spurious direct-digital-synthesis (DDS) source, enabling users to take accurate measurements with less phase noise interference. With the clean source signals, users can perform two-tone IMD measurements with close tone spacing previously only possible with high-performance analog signal generators. The new DDS sources also enhance the performance […]
Photovoltaic array simulators deliver 20 kW in a 3U format
A new family of photovoltaic (PV) array simulators are the first to deliver 2,000 V and 20 kW of power in a 3U format, enabling engineers to maximize solar power conversion. To keep solar power at grid parity with competing methods of power generation, performance and power conversion efficiency are critical. Small increments in power […]
Regenerative power supplies handle up to 20 kW and 2,000 V
The RP7900 Series of regenerative power supplies has expanded with the introduction of two new bidirectional, regenerative dc power supplies providing integrated safety features that protect people and devices under test (DUT). The regenerative design of the new models enables the energy normally consumed to be returned to the grid cleanly, saving costs associated with […]
6-GHz scope combines eight analog, 16 digital channels
The first oscilloscope with eight analog channels at 6 GHz and 16 simultaneous digital channels, enables users to reduce test bench and workflow complexity to boost performance as well as provide accurate and repeatable multi-channel measurements in a single instrument. High-speed digital designs, power integrity verification, Wi-Fi 6, IoT, IIoT and imaging and gallium nitride […]
How 5G changes the V2X communications game
The concept of vehicle-to-everything (V2X) communications has been around for 20 years. So far, V2X has achieved limited uptake for several reasons. That’s about the change with the widespread deployment of 5G technology. The 5G new radio (NR) standards contain several innovations that will change the game for V2X technology, saving lives, reducing fuel consumption,…
Economical two-channel scopes reach 200 MHz bandwidths
Four new 2-channel models of the InfiniiVision 1000 X-Series oscilloscopes provide 50 MHz to 200 MHz bandwidth, providing professional-level measurements and capabilities at an affordable price, including a standard decode function for five serial data protocols and remote connection via local area networks (LANs) and USB. The new InfiniiVision 1000 X-Series oscilloscopes use the same […]
Design package enables pre-compliance testing on SMPS virtual prototypes
Keysight Technologies announced a new add-on to PathWave Advanced Design System (ADS) that enables designers to perform pre-compliance testing on virtual prototypes of switched-mode power supply (SMPS) designs. This new capability saves the time and cost of iterative build and test of physical prototypes. Demand for SMPS is driven by the need for greater efficiency, increased power […]
Digital modulation basics, part 2: QAM and EVM
In Digital modulation basics, part 1 we examined the concept of quadrature modulation and signal generation. We showed a common block diagram for generating a quadrature signal (Figure 1). There is a corresponding receiver block diagram to extract the Inphase (I) and Quadrature (Q) components of the signal (Figure 2). The signal is converted to…
