Rohde & Schwarz NGM200 Series Power Supply

Manufacturer: Rohde & Schwarz
The single-channel R&S®NGM201 and the two-channel R&S®NGM202 deliver up to 60 W of output power per channel. The output  channels are floating, galvanically isolated and protected against overload and short circuits. Thanks to their high accuracy and fast load recovery time, the R&S®NGM200 power supplies are 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. High-speed data acquisition and convenient battery simulation widen the range of applications. With four measurement ranges for current and a resolution of up to 6½ digits when measuring voltage, current and power, the R&S®NGM200 power supplies are perfect for characterizing devices that have low power consumption in standby mode and high current in full load operation. In many cases, an additional digital multimeter is no longer necessary. Thanks to their fast recovery time of < 30 µs, their minimum overshoot even during a demanding load change and fast impedance regulation, the R&S®NGM200 power supplies are ideal for powering IoT devices and other battery-operated devices. With an acquisition rate of up to 500000 samples per second, even extremely fast variations in voltage or current can be captured. The linear two-quadrant design of the output stages allows the R&S®NGM200 power supply series to operate as a source and sink with minimum residual ripple and noise, ideally supporting the development of power amplifiers and MMICs. The optional battery simulation functionality provides test conditions that imitate the use of a real battery.
