The USB4 receiver test solution uses the Anritsu Signal Quality Analyzer-R MP1900A in combination with automation software from Granite River Labs or Teledyne LeCroy to control a connected oscilloscope and implement tests meeting the latest USB4 standards. The spread of next-generation 5G mobile communications and Internet of Things (IoT) devices is driving development of various […]
Protocol exerciser/analyzer handles PCI Express 5.0 work
The Summit Z58 PCI Express (PCIe) protocol exerciser/analyzer handles the testing of PCIe 5.0 designs and products. The Summit Z58 exerciser/analyzer addresses the needs of PCIe developers by providing high performance 32 GT/sec traffic generation on devices with link widths up to eight lanes and protocol analysis featuring Teledyne LeCroy’s industry standard CATC Trace. The […]
Test socket makes reliable connections to USB-C ports
Test sockets for making connections to smart phones and other devices employing USB-C ports are much more reliable and have a much longer life time than ordinary USB-C sockets. The XP2U-001 socket is designed as a one-touch connection to USB Type-C ports. The socket has a an expected lifetime of 200k insertions compared to 10k […]
Multi-channel LoRa-specific 1U rackmount tester handles transmitter/receiver signal evaluation
The GWInstek C-1200 LoRa Tester is a one-box tester that incorporates a multitude of LoRa transmit and receive tests. The C-1200 provides transmitter tests that include spectrum analysis, time domain, FEI (Frequency Error Indicator), and TOA (Time-On-Air). LoRa Receiver tests include sensitivity, BER (Bit Error Rate), and PER (Packet Error Rate). In addition to sub-gigahertz […]
Understanding electro-optic modulation
The electro-optic modulator is used to modulate a beam of light. Laser-controlled modulators are capable of operating in the gigahertz range, and modulation may be imposed on the amplitude, phase, or polarization of the beam. The component that makes this possible incorporates an element that exhibits an electro-optic effect, a change in its optical properties […]
New horizontal-mount OpenVPX chassis platform handles 3U, 6U, or hybrid versions
The first in the 1U SlimBox OpenVPX series is a three-slot version for 3U boards. A modular fixed power supply provides up to 600 W of power and one Rear Transition Module (RTM) is supported. A hybrid configuration option is available with 1x 6U slot and 1x 3U slot. In lieu of the fixed-mount power […]
Understanding and measuring optoelectronic oscillators
The problem with even a high-end electronic oscillator–such as a quartz crystal oscillator, dielectric resonator, sapphire resonator or air dielectric resonator–is that as the output frequency rises, excessive phase noise also rises. Optoelectronic oscillators are not subject to this and other dysfunctional high-frequency characteristics, and consequently they are suitable in certain exacting 21st century applications […]
Getting familiar with work-at-home instrumentation
The rise in social distancing has fostered a need for professional-grade test instruments that function as well at home as in the lab. David Horn | Digilent The events that have unfolded across the world since the beginning of 2020 have turned the global marketplace upside down. Few industries have felt this seismic shift as […]
Work-at-home tools: PC-based instruments address demanding applications
Advanced technology now lets budget-priced instrumentation handle tasks once requiring specialized and pricey test gear. Trevor Smith | Pico Technology Test & Measurement With a significant segment of engineers and researchers working at home or away from their lab during the pandemic, there is a large incentive to troubleshoot designs and validate performance using systems […]
Monitoring heart rate variability for better athletic ability
Sensors and sophisticated algorithms together deliver check heart-rate variability and other exercise metrics. Alisher Kholmatov, Recep Ozgun Micros, Security & Software Business Unit, Maxim Integrated From weekend warriors to professional athletes, most people who engage in regular sports activity take note of various factors that influence their performance. Some meticulously track certain metrics from game […]
