High precision source and sink

Due to their high accuracy and fast load recovery time, the R&S®NGL200 power supply series is perfect for challenging applications. Their two-quadrant architecture allows them to function both as a source and a sink to simulate batteries and loads. Their short recovery times enable them to handle fast load changes that occur for example when mobile communications devices switch from sleep mode to transmit mode.

Optimized load recovery time

Consumer electronics such as mobile phones and IoT devices require very little current in sleep mode. However, the current requirement increases abruptly as soon as they switch to transmit mode. A power supply used to power such DUTs must be capable of handling current increases from a few µA to the ampere range without creating voltage drops or overshoots.

Thanks to their fast load recovery time of < 30 µs even during a challenging load change, the R&S®NGL200 power supplies are ideal for powering IoT and other battery-operated devices.

6 ½ digit resolution

With a resolution of up to 6½ digits when measuring voltage, current and power, the R&S®NGL200 power supply series is perfect for characterizing devices with low standby power consumption and high current in full load operation. The entire measuring range is covered without having to switch ranges. This results in faster measurements. In many cases, an additional digital multimeter is no longer necessary.

Minimal ripple and noise

Advanced electronic circuitry is often very complex and sensitive to interference on the supply lines. In order to supply interference-free voltage to such sensitive DUTs, the power supplies must provide extremely stable output voltages and currents. All types of ripple and noise need to be avoided. The R&S®NGL200 power supplies have linear regulation and are ideal for sensitive DUTs.

Two-quadrant operation

The two-quadrant architecture of the R&S®NGL200 power supplies allows them to function both as a source and a sink and simulate batteries or loads. The power supply automatically switches from source to sink mode. As soon as the externally applied voltage exceeds the set nominal voltage, current flows into the power supply. This is indicated by a negative current reading.
