1. Linear design, reliable power supply for sensitive circuits

Advanced electronic circuits are typically very complex and highly sensitive to power line interference. The output stage adopts a linear design, therefore R&S ® The NGA100 power supply has very small residual ripple and noise. When developing sensitive components, it is necessary to provide stable output voltage and current.

2. High readback accuracy with comprehensive statistical function

R&S ® The NGA100 power supply series has excellent programming and readback accuracy, enabling accurate measurement and replication of the actual power consumption of devices even under low voltage and current conditions. Internet of Things (IoT) devices have multiple sleep modes, in which the device's current consumption is extremely low. In order to accurately determine these operational states, R&S ® The NGA100 power supply provides a low current measurement range. When measuring currents below 200mA, the resolution is 1 μ A and the accuracy can reach ± (0.15%+25 μ A). In addition, comprehensive statistics can display the minimum and maximum values of power, voltage, and current. The power supply has built-in measurement function, so there is no need to use an external multimeter, simplifying the device.

Low current measurement range

When the output current is ≤ 200 mA, the measurement resolution is 1 µ A

3. Flexible power combination to achieve high power under various operating conditions

R&S ® The NGA100 series provides maximum power under various operating conditions, covering a wider range of applications than single range power supplies. The corresponding flexible power curve displays all possible voltage and current combinations.

4. Channel fusion provides dual voltage or current function for power supply

R&S ® NGA102 and R&S ® The two output channels of NGA142 can provide higher voltage through series connection or higher current through parallel connection. After activating the series or parallel channel fusion function, the device will begin to function as a single channel power supply and have dual voltage or current capabilities.

In series mode, the output channels are internally connected, while in parallel mode, external wiring is required.

This feature ensures that the power supply can be used independently for a wider range of applications.
