The R&S®NGL200 Power Supply Series from Rohde & Schwarz is a performance-class bench and system power supply line built around a linear two-quadrant output stage. It is offered in two base configurations: the single-channel R&S®NGL201 and the two-channel R&S®NGL202, with each channel delivering up to 60 W of output power. The output channels are floating, galvanically isolated, and protected against overload and short circuits. Because the two-quadrant architecture lets each channel act as both a source and a sink, the series can supply power to a device and also absorb power from it, automatically switching to sink mode and indicating the transition with a negative current reading.

Rohde & Schwarz designed the R&S®NGL200 series for powering IoT devices and other battery-operated devices, where the load current can rise abruptly from a few microamps in sleep mode to the ampere range when the device switches to transmit mode. The two-quadrant design lets the supplies simulate batteries and loads, while the high measurement resolution makes them well suited to characterizing devices that draw very low power in standby and high current at full load — in many cases removing the need for a separate digital multimeter. The minimum residual ripple and low noise of the linear regulation support the development of sensitive circuitry such as power amplifiers and MMICs. The supplies are used in R&D labs and integrated into production test systems and ATE applications.

ValueTronics keeps its inventory on hand in a 20,000 square-foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, where we stock and hold the instruments we sell. That combination lets us match the right instrument and condition to your application and stand behind every order.

Brand Heritage

Compare Other Models in This Series

The R&S®NGL200 series sits in Rohde & Schwarz's performance class of power supplies — the tier intended for applications where speed, accuracy, and advanced programming features matter, including DUT protection, fast programming times, and downloadable voltage and current sequences for lab and ATE use. The series comprises two base models that share the same per-channel performance but differ in channel count and total output power.

Both the single-channel R&S®NGL201 and the two-channel R&S®NGL202 use the same linear two-quadrant output stage, the same 0 V to 20 V output range, and the same protection, measurement, and programming feature set. The choice between them is primarily a question of how many isolated channels an application needs and how much total output power it requires.

Each model below has its own dedicated product page with new-matched pricing. Select the R&S NGL201 or R&S NGL202 page that matches your channel and power requirement to see the configuration and pricing for that specific new unit.

The clearest difference is channel count: the R&S®NGL201 is a single-channel supply rated at 60 W total, while the R&S®NGL202 carries two channels for up to 120 W total (60 W per channel). Because the R&S®NGL202's channels are galvanically isolated, they can run independently, be paralleled for up to 12 A (at ≤ 6 V output), or be connected in series for up to 40 V — and a FuseLink function can tie the two channels' electronic fuses together so both switch off as one.

A few connector and function details also differ. The R&S®NGL201 adds sense-line connectors on the front panel in addition to the rear, whereas the R&S®NGL202 provides front-panel safety sockets for its channels with sense connections on the rear panel. Electronic-load operation, the sense function, and the protection settings are available on both models, and on the R&S®NGL202 they apply to both channels. The comparison table below summarizes the per-model figures.

Product Core & Specifications

Important: Maximum voltage to ground: 250 V DC.

Important: Maximum sink power for the R&S®NGL202 (120 W, 60 W per channel) is time limited at an operating temperature of > 30 °C and total power > 90 W.

Important: The WLAN function (R&S®NGL-K102 option) is not available in all regions due to country-specific regulations.

Important: The R&S®NGL-K102 (WLAN) and R&S®NGL-K103 (digital trigger I/O) options are activated using a keycode that must be ordered separately.

Recommended pairing: install the R&S NGL200 supplies in 19" racks using the R&S HZN96 rack adapter (2 HU) listed in the ordering information.
