DESCRIPTION:
The Rohde & Schwarz NGU401 is a precision Source Measure Unit designed for engineers requiring highly accurate sourcing and measurement capabilities within a single instrument. Combining the functions of a DC power supply, battery simulator, digital multimeter, and measurement system, the NGU401 is particularly suited to testing and characterising modern battery-powered electronic devices.
The instrument provides a programmable output range from 0 V to 20 V with output currents up to 8 A and a maximum output power of 60 W. Its single-quadrant architecture enables highly stable power sourcing while simultaneously measuring voltage, current, power, and energy with exceptional precision.
Designed for low-power electronics and mobile device development, the NGU401 offers high-speed acquisition and fast transient response, enabling accurate capture of rapidly changing current consumption profiles. This capability is especially valuable for IoT devices, wireless modules, sensors, smartphones, wearables, and embedded systems where standby and peak current measurements are critical.
Integrated battery simulation functionality allows engineers to emulate realistic battery behaviour during development and validation testing. The instrument also supports high-resolution current measurements, making it suitable for analysing sleep modes, transmit cycles, and power-saving operation in modern electronic products.
USB and LAN interfaces support remote operation and automated testing, while the intuitive front panel and colour display simplify bench-top operation. Advanced triggering, logging, and measurement functions enable integration into research laboratories, development facilities, and automated validation environments.
