The two-quadrant architecture of the NGM200 power supply series from Rohde & Schwarz allows it to be used as a source and sink for simulating batteries and loads. Rapid load changes, e.g. when switching from sleep mode to the active mode of mobile devices, can be absorbed by the short settling time. The devices are available with one channel (NGM202) or as a 2-channel device (NGM201), with an output power of 60 W per channel. The outputs are floating and galvanically isolated.
The power supply units in the NGM200 series are protected against overload and short circuit. A 6½-digit digital multimeter for measuring voltage, current and power is integrated. With the fast stabilization time of < 30 μs, the very low overshoot even with sudden load changes and the fast impedance regulation, the power supply units are ideal for supplying power to IoT devices and other battery-operated devices. With a sampling rate of 500 kS/s, very fast voltage and current changes can be recorded. An optionally available battery simulation function imitates the real conditions of a battery supply for a device under test.
Fast load regulation
Battery-operated consumer electronics devices or cell phones and IoT devices require very little power in sleep mode. However, the current increases abruptly as soon as the device switches to transmit mode. The power supply for such devices under test must be able to cope with load changes of a few μA up to the ampere range without causing voltage drops or overshoots. With the NGM200 power supply units, the user can determine how these rapid load changes are to be regulated. The default "Fast" setting is optimized for speed and achieves recovery times of < 30 μs.
Minimal ripple and low noise
The NGM200 family power supplies feature linear regulation and are ideal for sensitive DUTs. Many power supply units usually react to sudden load changes with overshoot and slow recovery times. Thanks to the optimized control loop, however, the NGM200 series achieves settling times of less than 30 μs.
