The Rohde & Schwarz HMP2020 is a two-channel programmable DC power supply delivering 188 W total output power across independent channels rated 0–32 V, with Channel 1 providing 0–10 A (160 W max) and Channel 2 providing 0–5 A (80 W max). Built-in linear regulation achieves voltage ripple below 1.5 mVrms and current noise under 1 mArms, with 1 mV voltage resolution and 0.1–1 mA current resolution depending on range. The 240 × 64 pixel LCD display and intuitive interface support both benchtop operation and 19″ rack integration.
