R&S NGU Source Measure Unit 2021.02. 신제품

최고의 전원 공급기

R&S®NGU SMU(Source Measure Unit)는 매우 높은 정확도와 빠른 부하 복구 시간으로 까다로운 작업에 적합합니다. 특수 전류계를 사용하여 nA 단위부터 A 단위까지의 전류 드레인을 한 번에 정밀 측정하므로, 여러 번의 측정 스윕이 필요하지 않습니다. 또한, 기기의 복구 시간이 짧아 이동통신 기기가 절전 모드에서 송신 모드로 전환할 때와 같은 빠른 부하 변화를 처리할 수 있습니다. 빠른 데이터 획득 속도로 모든 상세 정보를 2 μs의 분해능으로 탐지합니다. R&S®NGU Source Measure Unit은 Two-quadrant 또는 Four-quadrant 구조로 소스 및 싱크로 작동 가능합니다.

주요 사항

기능 및 이점

Two/Four quadrant: 소스와 싱크로 작동 Simulates batteries or loads The two/four-quadrant architecture of these source measure units allows them to function both as a source and a sink and simulate batteries or loads. The SMU automatically switches from source mode to sink mode as soon as the externally applied voltage exceeds the set nominal voltage. With its four-quadrant architecture, the R&S®NGU401 can supply positive or negative voltages or currents and can act as a source or sink in both polarities.
고속 데이터 획득 FastLog functionality The R&S®NGU source measure units offer the FastLog function 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.
Voltage Priority 또는 Current Priority mode Optimized for voltage/curent regulation In voltage priority mode, fast voltage regulation provides short recovery times of less than 30 μs. Current regulation is designed to be somewhat slower to avoid a tendency to oscillation. When precise and quick current regulation is desired, the R&S®NGU source measure units can be operated in current priority mode. Optimized for fast current regulation (load recovery time < 50 μs), this mode allows tasks such as LED testing, which are sensitive to even short current spikes.
High-capacitance mode Compensate capacitors Quite often in a typical measurement configuration, there is a capacitance at the input of the DUT. Connecting the power supply by leads results in a low pass behavior formed by the leads and the capacitance. Providing the high-capacitance mode, the R&S®NGU source measure units compensate the capacitance and display the current directly at the DUT.
빠른 부하 조정 Handles fast load changes 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 nA to the ampere range without creating volt­age drops or overshoots.
