The re-engineered and improved the EPCOS LeaXield active leakage current filter is able to minimize earth leakage currents in converter-based drive systems. LeaXield is designed for applications in variable-speed drives such as those in machine tools, pumps, compressors, conveyance systems, and other pluggable devices. In these systems aggregate earth leakage currents can cause RCDs (residual […]
Ultra-precision current-sense chips feature resistance range to 80 mΩ
The CSSH2512 from Stackpole is an all metal current sense chip resistor capable of precision tolerances as low as 0.5% and TCR as low as 15 ppm. The resistance range for the 3-W 2512 size chip has been expanded and now spans from 0.5 mΩ up to 80 mΩ. The high precision combined with the […]
Free firmware brings mixed-domain analysis to MSOs
Tektronix today released new firmware for the 5 Series and 6 Series MSO mixed signal oscilloscopes that unlocks a new analysis tool called Spectrum View. A free upgrade, Spectrum View allows you to perform mixed domain analysis on the big, high-resolution displays of the 5 and 6 Series MSOs. This mixed domain capability can be […]
How AC power sources get synchronized
Today’s huge ac grids consist of many separate generators with new ones continually coming on line. When a generator is powered down for maintenance or even temporarily disconnected, it must resynchronize upon rejoining the grid, generally by automatic means with manual backup instrumentation in place if needed. The process of synchronizing ac power sources to […]
Embeddable DVR simultaneously records HD on two USB devices
The analog HD DVR Model 4023 captures JPEG snapshots without video interruption while it simultaneously makes HD recordings from two SUB devices. Outputs are either HD or composite and are selectable from playback/review. The DVR can be operated wirelessly with an external WiFi adapter. The unit features real-time video overlay of date and time and […]
Teraohmmeter excels at higher voltage insulation resistance testing
The 98x Series of Teraohmmeter/Insulation Resistance testers are designed to meet the emerging higher voltage requirements of electric vehicle battery systems and solar arrays. The 981i offers an output voltage range of up to 6.5 kV and the 983i has a maximum output of 11 KV. Built upon the same DSP technology that has established […]
Open-top spring pin socket for 1-mm-pitch BGA packages
A new socket addresses high-performance requirements for burn-in and test applications. Called the SBT-BGA-6044, the socket contains a contactor that is a stamped spring pin with 19-gm actuation force per ball and cycle life of 125,000 insertions. The self-inductance of the contactor is 0.93 nH, insertion loss of < 1 dB at 14.1 GHz and […]
Optical device tester for 100G/400G gets 4-channel scope option
A 4-channel sampling oscilloscope option is now available for the Anritsu BERTWave MP2110A, creating a comprehensive single-instrument solution that integrates an oscilloscope and 100G BERT. With the option, the BERTWave can cost-efficiently and accurately evaluate the physical layer performance of 100G/400G optical transceiver modules, active optical cables (AOCs), direct attach cables (DAC), and high-speed optical […]
