Power demand is moving from hundreds of kilowatts toward multi-megawatt systems across AI data centers, aerospace and defense, battery energy storage, and other high-power applications. As voltage, current, and transient requirements climb, fixed test infrastructure can limit growth, waste energy, and force early replacement.

This application note explains the market forces behind the megawatt mandate and shows how configurable Tektronix high-power DC racks help test teams add voltage and power headroom, emulate fast dynamic loads, recover energy, and protect long-term test investments.
