Conventional analog circuitry has been consolidated into the digital domain to
benefit from its inherent stability, and to enable new levels of functionality and
adaptability that is not practical with the analog approach.

FEATURES
The ReFlex Power™ system of HP/LP Active Loads brings modularity to active
load assets, and makes possible a high degree of reconfigurability and
adaptability through a Mainframe-based architecture. It extends the modular
configuration to high power Active Load assets, without compromising
performance or the controls feature set. The mechanical design is ruggedized for
harsh environments, including mobile applications, as well as general-purpose
industrial and laboratory rack-mount ATE.
