T&M upgrades support coherent module, silicon photonics test applications
VIAVI has released six major enhancements to the LightDirect family of modules for the MAP-300 test platform, which was introduced last year, with specific focus on supporting coherent module and silicon photonics test applications. · New high power, C+L band, continuously tunable laser module, the mTLS-C1, the most compact on the market for its performance […]
Difference between measuring resistance and conductivity
Generally, an electrical conductor is a long solid rod, often insulated. It may be rectangular, like the electrician’s bus bar, irregular in cross section, or it may be merely a conductive path through the atmosphere, created by a process of ionization. Most electronics professionals have measured the resistance of conductors typically using a volt-ohm meter. […]
Data streaming/visualization platform works with logging, 6.5-digit DMMs
A native integration mates the Keithley DAQ6510 and DMM6500 instruments with Initial State, an loT dashboard for data streaming and visualization for world-class, remote data access. Keithley and Initial State, both Tektronix companies, collaborated to integrate Initial State’s data streaming and visualization platform with the Keithley graphical DAQ6510 and DMM6500. This integration gives a DAQ6510/DMM6500 […]
