A digital low-resistance ohmmeter can deliver reliable results when using long test leads. The DLRO2, a 2-A handheld tester, is a candidate for use in production line testing and industrial applications. This robust and intuitive handheld instrument offers a ‘difference meter’ that allows for quick data comparisons. Applications that require long test leads are not […]
The difference between measuring magnetic flux and magnetic fields
Simply stated, a magnetic field is analogous to electrical voltage, while magnetic flux is analogous to electrical current. A magnetic circuit is analogous to an electrical circuit with important differences. Electromotive force in an electrical circuit corresponds to magnetomotive force. Resistance and its reciprocal, conductance, in an electrical circuit corresponds to reluctance and its reciprocal, […]
3U and 6U OpenVPX power and ground backplanes speed prototyping
3U and 6U OpenVPX power and ground backplanes come in several configurations. With the SOSA/HOST efforts and move to optical and RF interfaces over OpenVPX, Pixus has developed multiple styles that allow for versatility in prototyping. The 1-slot backplanes come in VITA 65 (VPX only), VITA 66.4 (optical), and VITA 67.3 (RF) formats. The optical […]
Analyzer platform handles protocol analysis checks for PCI Express 5.0
The Xgig 5P8 Analyzer Platform for PCI Express 5.0 allows equipment manufacturers to ensure performance in accordance with the latest revision of the ubiquitous serial computer expansion bus standard. The PCIe 5.0 standard doubles data capacity over a PCIe link to 32 gigabits per second per unidirectional channel, or greater than one terabit per second […]
Modular test platform helps validate ADAS, autonomous driving functions
A modular test platform is said to accelerate the validation of advanced driver-assistance systems (ADAS) and functions for autonomous driving. Keysight, IPG Automotive and Nordsys have established a multi-year collaboration to create the Autonomous Drive Emulation (ADE) platform, a setup which will emulate synchronized connections to all relevant sensors in a car such as the […]
Test software helps evaluate C-V2X PC5 communications technology
The LTE C-V2X PC5 Communications Software MX725000A provides engineers with a cost-efficient tool to evaluate products and systems utilizing PC5 of Cellular V2X (C-V2X) technology. The software links a communications reference module, V2X emulator software, and GNSS simulator to support evaluation of vehicle-to-everything (V2X) PC5 communications used in emerging vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) designs. […]
Bi-phase modulators cover frequency bands from 0.5 to 40 GHz
A new line of bi-phase modulators includes a comprehensive selection of nine different models covering broad octave frequency bands ranging from 0.5 to 40 GHz. Bi-phase modulators take a TTL-level digital bit stream that is encoded onto the RF carrier using 2 Phase Shift Keying (2PSK) modulation, where the two phases are separated by 180°. […]
48-Channel threshold comparator card handles event monitoring and control tasks
The new GX3748 Series 48-Channel Threshold Comparator Card combines 48 voltage-comparator channels with windowing and precision level detection, to deliver an event monitoring and control solution. Triggers can be generated, based on user programmable voltage threshold levels, enabling time-critical response when out-of-limit test conditions occur. Additionally, multiple high-density comparator cards can easily be combined in […]
Practical measurement of feedback loops and their stability
Feedback is relevant not only to electronic circuits but also to all kinds of natural and human-based phenomena ranging from mechanical engineering to economics and finance. Feedback emerges when one or more system outputs are connected back to system inputs. If polarity is inverted, it is an instance of negative feedback, which in electrical circuits […]
Spectrum analyzers with tracking generator provide vector network analysis up to 6.5 GHz
The Rigol RSA3000 and RSA5000 Real Time Spectrum Analyzer series now includes five “N” versions which offer vector network analysis up to 6.5 GHz. Built on Rigol’s Ultra Real platform, these VNAs offer S11 and S21 reflection and transmission analysis. They feature multi-touch user control via a 10.1-in. LCD touchscreen. Front panel buttons, keyboard, and […]
