Discussions of signal jamming were once largely confined to electronic warfare forums. But with the rise of autonomous vehicle technology, jamming has become a mainstream topic. It now pays to know a few basics about both the test setups necessary to gauge resistance to jamming techniques and the principles of signal propagation. Many of the […]
BER analyzer gets multichannel support, FEC pattern generation
The Signal Quality Analyzer-R MP1900A BERT has been enhanced with four PAM4 BERT options adding multichannel synchronization, multilane FEC pattern generation for 400 GbE, Inter Symbol Interference (ISI) stressed signal generation to simulate transmission path losses, and application software for capturing device-under-test (DUT) error counts. The new options allow engineers to more accurately and efficiently […]
Spectrum analyzer package handles 3D mapping for 5G NR apps
A spectrum analyzer package that provides 3D indoor and outdoor coverage mapping for 5G New Radio (5G NR) integrates the Field Master Pro MS2090A RF handheld spectrum analyzer with the MA8100A TRX NEON Signal Mapper. The integrated field test solution allows wireless professionals deploying 5G NR to conduct more accurate measurements than conventional instruments using […]
Protocol analyzer platform wrings out next-generation USB4
Teledyne LeCroy has developed the first protocol analyzer platform for testing next-generation USB4 and Thunderbolt 3 systems. The convergence of the underlying Thunderbolt and USB protocols in the USB4 specification will increase compatibility among USB Type-C connector-based products, simplifying how people connect their devices. Teledyne LeCroy’s new Voyager M4x Protocol Analyzer will enable companies to […]
Clamp meters handle ac currents up to 2,000 A
The Hioki CM4141 and CM4142 AC Clamp Meters are rated for use with currents up to 2,000 A. These new current sensors feature a compact, sturdy jaw design for easy application around existing wiring, robust enough to push and pull wiring. The CM4141 and CM4142 deliver accurate results even when measuring ac current waveforms that […]
Measuring Ethernet and WiFi transmissions
The Ethernet computer networking protocol is used in local area networks, metropolitan area networks and wide area networks. While the term is often used to distinguish wired data transmissions from Wi-Fi, both use parallel protocol details, notably 48-bit MAC address and Ethernet frame format. Actually, Wi-Fi is Ethernet over a different medium. There are a […]
Software runs USB 3.2 transmitter and receiver compliance tests
A new automated compliance test package handles USB 3.2 transmitter and receiver compliance testing to the QPHY-USB3.2-Tx-RX spec. USB 3.2 is the latest iteration of the USB spec, allowing multi-lane operation: either two lanes at 5 or 10 Gb/sec, enabling a maximum transfer rate of 20 Gb/sec (Gen2x2). To that end, Teledyne LeCroy developed the […]
The difference between spontaneous emissions and stimulated emissions
The terms spontaneous emission and stimulated emission sometimes get confused. The term thermal emission sometimes gets thrown into the mix as well. Here are the basic definitions to help sort things out and the procedures for measuring these parameters. When we speak of spontaneous or stimulated emissions we are referring to atoms whose electrons are […]
First integrated dual-channel 44-GHz vector signal generator with 2-GHz bandwidth
Dual-channel microwave signal generators support up to 44 GHz signals and 2-GHz RF modulation bandwidth in a single instrument. Keysight’s new VXG microwave signal generators address the most demanding wideband millimeter wave (mmWave) applications for 5G and satellite communications by decreasing test set-up complexity and reducing path losses introduced in over-the-air (OTA) test environments. Many […]
Rugged real-time spectrum analyzer/RF recorder works up to 20 GHz
The Spectran XFR V5 PRO Real-Time Spectrum Analyzer is a portable, rugged RF detection device designed to capture even the briefest signal transmissions. Its rapid signal acquisition scans a 20-GHz bandwidth in less than 20 msec, making it the world´s fastest counter-surveillance receiver. The instrument’s internal GPS also indicates the precise location of the measured […]
