Description
Aperçu
L'alimentation CC bicanal Rohde & Schwarz NGM202 est une alimentation de grade professionnel conçue pour le test d'appareils électroniques sensibles nécessitant une mesure précise de tension et de courant. Avec le fonctionnement à deux quadrants, elle agit à la fois comme source d'énergie et comme charge électronique, ce qui permet une simulation réaliste de batterie et un test du comportement en régime transitoire. Le NGM202 est particulièrement adapté aux applications exigeant une résolution de mesure élevée et des capacités d'acquisition de données rapides.

Caractéristiques techniques
| Battery Simulation | Real batteries show different characteristics depending on the type of battery and its charging condition. Capacity, open circuit (Voc) and equivalent series resistance (ESR) are important battery characteristics that depend on its state of charge (SoC). The optional NGM-K106 functionality allows users to simulate the behavior of batteries under different charging conditions; e.g. when powering a DUT |
| High Speed Acquisition | The NGM200 power supplies offer the high-speed FastLog functionality to capture voltage and current measurement results. This data can be stored on an external USB storage device or can be transferred to an external PC via USB or LAN. With an acquisition rate of up to 500 ksample/s, voltage and current results are available every 2 μs. Instead of the readback voltage, also the voltage measured by the optional digital voltmeter functionality (NGM-K104) can be logged with 500 ksample/s. Using the two-channel NGM202, the data acquisition can run on both channels in parallel. With this high-speed acquisition, even spikes in the microsecond range that cannot be detected with slower instruments, can be detected in min./max. values. |
| Digital Voltmeter Functionality | Like other power supplies, the NGM200 instruments measure the voltage supplied to the DUT. In addition, the NGM-K104 option activates a port that allows the internal digital voltmeter to be connected to any other point in the customer's circuitry. In many cases, an additional digital multimeter is not necessary. |
| 6½ Digit Resolution | With a resolution of up to 6½ digits when measuring voltage, current and power, the NGM200 power supplies are perfect for characterizing devices that have low power consumption in standby mode and high current in full load operation. Two voltage measurement ranges and four ranges to measure current provide a high accuracy and resolutions down to 1 μV/10nA. |
| Fast Load Regulation | Consumer electronics such as mobile phones and IoT devices require very little power in sleep mode. However, the current increases abruptly as soon as the device switches to transmit mode. A power supply used to power such DUTs must be capable of handling load changes from a few µA to the ampere range without creating voltage drops or overshoots. The NGM200 power supplies have a circuit design that allows the user to determine how the power supply regulates load changes. The “Fast” default setting is optimized for speed, achieving recovery times of < 30 µs. Deactivating “Fast” slightly increases the recovery time, focusing on preventing overshoots under special load conditions. The NGM200 power supplies regulate the output impedance very fast. Especially in the range from –50 mΩ to 2 Ω, recovery times of < 200 µs can be achieved. |
| Minimum Residual Ripple and Low 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 NGM200 power supplies have linear regulation and are ideal for sensitive DUTs. |
