New Two-Quadrant Power Supply Series for Mobile Communications and IoT Sectors

With high accuracy and fast load recovery time from Rohde & Schwarz

Thanks to their high accuracy and fast load recovery time, the new R&S NGL200 power supplies are perfect for challenging applications in mobile communications and the internet of things (IoT). Their two-quadrant architecture allows them to function both as a source and a sink. Their short recovery times enable them to handle fast load changes that occur for example when a device switches from sleep mode to transmit mode.

The new R&S NGL200 power supply series from Rohde & Schwarz specifically addresses users in the mobile communications and IoT sectors. The single-channel R&S NGL201 and the two-channel R&S NGL202 deliver up to 60 W of output power per channel. The output channels are floating, galvanically isolated and protected against overload and short circuits. The power supplies can sink power in a controlled manner, enabling them to simulate the specific characteristics of a battery. This series also sets new standards with its capacitive touchscreens and large, high-resolution displays. The optimized user interface is especially intuitive, and temperature-controlled fans ensure extremely quiet operation. Extensive safety functions safeguard the DUT and the power supply in the event of a fault.

Extremely fast load recovery time

Power supplies used to power IoT devices and other battery-operated devices or to test semiconductors must be able to handle load changes from a few µA to the ampere range without voltage drops or overshoots. Thanks to their fast load recovery time of less than 30 microseconds and minimal overshoot, these power supplies are ideal for such tasks.

Operation as source or sink

The linear two-quadrant design of the output stages enables the R&S NGL200 power supplies to operate as a source and sink, with automatic switching from source mode to sink mode.

Minimum residual ripple and low noise

The R&S NGL200 power supplies feature linear regulation to deliver extremely stable output voltages and currents. This makes them the right choice for powering sensitive modules and for developing power amplifiers and MMICs.

Readings with up to 6 ½ digit Resolution

With up to 6 ½ digit resolution for voltage, current and power measurements, the R&S NGL200 series is ideal for characterizing devices that have low power consumption in standby mode and high current in full load operation. The entire measuring range is covered without having to switch ranges, speeding up measurements. In many cases, an additional digital multimeter is not necessary. This saves space and money and simplifies test setups.

Interfaces, options and Prices

In addition to channel outputs, the R&S NGL200 series provides connectors for sense lines. USB and LAN interfaces are installed as standard for remote control. The R&S NGL-K102 option adds WLAN support. Digital inputs and outputs are available with the R&S NGL-K103 option, and the R&S NGL-B105 hardware option provides a GPIB (IEEE-488) interface.

The new R&S NGL200 power supply series is available now from Rohde & Schwarz and selected distributors. Prices start at EUR 1,900 for the single-channel R&S NGL201 and at EUR 2,900 for the two-channel R&S NGL202. More information is available at: https://www.rohde-schwarz.com/product/ngl200
