Rohde & Schwarz NGU Source Measurement Units

With very high accuracy and fast load recovery time, NGU source measure units (SMUs) are designed to meet application-specific challenges.

Emulate the unique characteristics of a specific battery model
Test battery capacity, SoC and V_oc to test devices under specific battery conditions
Simulate electronic loads to accurately sink current and dissipate power in a controlled manner

What sets the NGU-series apart?

Few SMUs can match the NGU for interference-free voltage. With extremely low residual ripple and noise, the NGU is ideal for testing sensitive devices.

Fast Load Recovery

Dealing with very fast load changes—like when a smartphone switches from sleep mode to transmit? These SMUs keep up, plus High-speed data acquisition detects every detail down to 2 μs resolution.

Source and Sink

Need to simulate batteries and loads? NGU SMUs offer two- or four-quadrant architecture to provide up to 60 W of power source or power sink. The channels are floating, galvanically isolated, and protected against overload and short circuits.

Six Measurement Ranges

Measure six ranges of current with resolution up to 6 1⁄2 digits when measuring voltage, current and power. Characterize devices with extremely low power consumption as well as high currents in the ampere range with sensitivity down to the nA range.

Featured Product: Rohde & Schwarz NGU201COM

The NGU201COM is the ideal two-quadrant SMU for testing wireless communications devices. It handles abrupt load changes with minimal overshoot, analyzes fast variations in voltage and current, and offers realistic battery simulation features.
