High precision source and sink

Its accuracy and fast load recovery times make the R&S®NGL200 DC power supply series ideal for challenging applications, such as:
- Battery tests
- Power consumption tests
- Simulation of voltage drops
- Supplying sensitive designs
The two-quadrant architecture allows the R&S®NGL200 to function both as a source and a sink to simulate batteries and loads. The short recovery time means the DC power can handle fast load changes when mobile communications devices switch between sleep and transmit modes.
Choosing the R&S®NGL200 has never been easier. With our new online configurator you can choose the DC power supply and options you need with full price transparency.

Features & benefits

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 for 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 fast load recovery times of < 30 µs even for challenging load changes, R&S®NGL200 power supplies are ideal for powering IoT and other battery-operated devices.

**Exceptionally fast load recovery time** - Power supplies usually respond to abrupt load changes with overshoot and slow recovery times. Specially optimized control circuits enable R&S®NGL200 power supply recovery times of < 30 µs.

6 ½ digit resolution

With a resolution of up to 6½ digits when measuring voltage, current and power, the NGL200 power supply series is ideal 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 supply line interference. When supplying interference-free voltage to sensitive DUTs, power supplies must provide extremely stable output voltage and current. All forms of ripple and noise must be avoided. R&S®NGL200 power supplies have linear regulation and are ideal for sensitive DUTs.

Two-quadrant operation

The two-quadrant architecture of R&S®NGL200 power supplies can function both as a source and a sink to 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.

**Source and sink operation** - R&S®NGL200 power supplies automatically switch from supply mode to load mode. Here, channel 2 is operating as a load. This is indicated by a negative current reading.
