When it comes to amplification, the principal parameters are gain and fidelity of the output relative to the input. Gain, denoted by β (Greek letter beta), is the ratio of output voltage, current or power to input. An amplifier by definition has a power gain greater than one. Measurements that characterize amplifier gain serve as […]

Test setup handles IEEE 802.3cg 10BASE-T1S compliance for auto industry apps
The first 10BASE-T1S compliance test setup has been developed for the R&S RTO and R&S RTP oscilloscopes, which will provide fully automated testing conforming to the current version of IEEE 802.3cg 10BASE-T1S interfaces. Rohde & Schwarz continues to participate actively in the OPEN Alliance, using its expertise to help drive the development of complete and […]
The modern economics of renting test instruments
The development of online instrument exchanges puts a new wrinkle into how to get the optimum use of test gear. LEE TESCHLER EXECUTIVE EDITOR When a project comes up that involves expensive test gear like gigahertz-range signal analysis, statistics from the Equipment Leasing & Finance Foundation show this kind of instrumentation is increasingly acquired through […]
Testing RF power amps with scopes
by Mike Borsch and Mike Schnecker, ROHDE & SCHWARZ Modern transceivers often incorporate several parallel RF front ends whose control signaling can be sorted out with advanced instrumentation. The radio frequency (RF) front-end configuration in mobile devices continues to evolve and get better. The trend in mobile radio communications is toward complex multi-radio systems perhaps […]
