Description
Overview
The Rohde & Schwarz NGL202 is a precision DC power supply designed for challenging applications requiring high accuracy and fast load recovery. Its two-quadrant architecture allows operation as both a source and a sink to simulate batteries and loads, with short recovery times enabling rapid response to fast load changes typical of mobile communications and IoT devices switching between sleep and transmit modes.
Key Features
- Maximum output power: 120W
- Voltage per channel: 0V to 20V
- Maximum current per channel: 6A
- Load recovery time: <30µs
- Ripple and noise: <500µV (RMS) / <1mA (RMS)
- 6½ digit resolution for voltage, current, and power
Key Benefits
Optimized Load Recovery Time
Mobile and IoT devices require minimal current in sleep mode but demand high current during transmission. The NGL202's 30µs recovery time handles challenging load transitions without voltage drops or overshoots, making it ideal for powering battery-operated devices.
High-Resolution Measurements
With 6½ digit resolution, the NGL202 accurately measures voltage, current, and power across its entire range without switching ranges. This enables faster measurements and often eliminates the need for an additional digital multimeter.
Minimal Ripple and Noise
Linear regulation provides extremely stable output with minimal ripple and noise, protecting sensitive electronic circuits and advanced designs from supply-line interference.
Two-Quadrant Operation
The power supply automatically switches between source and sink modes, functioning both as a source and as a load simulator. When external voltage exceeds the set level, current flows into the power supply, indicated by negative current readings.
Applications
- Battery testing and characterization
- Power consumption measurements for mobile and IoT devices
- Voltage drop simulation
- Powering sensitive devices during development and testing
Specifications
| Optimized Load Recovery Time | Consumer electronics such as mobile phones and IoT devices require very little current in sleep mode. However, the current requirement increases abruptly as soon as they switch to transmit mode. A power supply used o power such DUTs must be capable of handling current increases from a few μA to the ampere range without creating voltage drops or overshoots. Thanks to their fast load recovery time of 30μs even during a challenging load change, the NGL200 power supplies are ideal for powering IoT and other battery-operated devices. |
| 6½ Digit Resolution | With a resolution of up to 6½ digits when measuring voltage, current and power, the NGL200 power supplies are perfect 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. This results in faster measurements. In many cases, an additional digital multimeter is no longer necessary. |
| Minimal Ripple and Noise | Advanced electronic circuitry is often very complex and sensitive to interference on the supply lines. In order to supply interference-free voltage to such sensitive DUTs, the power supplies must provide extremely stable output voltages and currents. All types of ripple and noise need to be avoided. The NGL200 power supplies have linear regulation and are ideal for sensitive DUTs. |
| Two Quadrant Operation | The two-quadrant architecture of the NGL200 power supplies allows them to function both as a source and sink and simulate batteries or loads. The power supply automatically switches from source to sink mode. As soon as the externally applied voltage exceeds the set nominal voltage, current flows into the power supply. This is indicated by a negative current reading |
