Features & benefits

Linear design

Confidently power sensitive circuits

Advanced electronic circuitry is often complex and sensitive
to supply line interference. The linear design of the output stages allows the R&S®NGA100 power supplies to operate with minimum residual ripple and noise. Supplying extremely stable output voltage and current is crucial when developing sensitive components.

High readback accuracy

With integrated statistics

R&S®NGA100 power supplies have outstanding programming and readback accuracy to precisely measure and replicate actual device power consumption, even at low voltage and current levels. IoT devices can have multiple sleep modes where current consumption is very low. To accurately determine these operating states, R&S®NGA100 power supplies have a low-current measurement range. Currents below 200 mA are measured with a resolution of 1 μA and an accuracy of ±(0.15 % + 25 μA). In addition, integrated statistics show the min. and max. values for power, voltage and current. These built-in measurements reduce the need for external multimeters and simplify the setup.

**Low-current measurement range** - For output currents ≤ 200 mA the measurement resolution is 1 µA

FlexPower

Get the maximum power at various operating points

The R&S®NGA100 series operates with maximum power at various operating points and covers far more applications than single range power supplies. All possible voltage and current combinations are shown in the corresponding FlexPower curves.

Channel Fusion

Double the voltage or current capability of your power supply

The two output channels of the R&S®NGA102 and R&S®NGA142 operate in series or parallel for higher voltage or current. After activating serial or parallel channel fusion, the device will start to act like a one-channel power supply with double voltage or current capability.
In serial mode the outputs are connected internally, while the parallel mode requires external wiring.
The function enables even more applications to be covered by a single instrument.

**R&S®NGA142 in channel fusion serial mode** - Extended voltage range up to 200 V
