Rohde & Schwarz NGPQ32/6 Power Supplies DC

The Rohde & Schwarz NGPQ32/6 is a single-channel programmable DC power supply engineered for laboratory and test applications requiring precise, low-noise power delivery. Rated at 48 W maximum output, this linear-regulated supply delivers three independently selectable voltage/current ranges: 0–8 V / 0–6 A, 0–16 V / 0–3 A, and 0–32 V / 0–1.5 A. Voltage resolution reaches 1 mV, while current resolution spans 100 µA (6 A range) and 1 µA (100 mA range).

Ripple and noise performance is specified at ≤0.6 mV RMS, with fast transient load response optimized for mobile communication device testing and battery simulation.
