R&S®NGL200 - Alimentations et charges

Sources et charges de haute précision

• Grâce à sa grande précision et à son temps de récupération de charge rapide, la série d’alimentations R&S®NGL200 est idéale pour les applications difficiles.
• Son architecture à deux quadrants lui permet de fonctionner à la fois comme source et comme charge pour simuler des batteries et des charges.
• Son temps de récupération court lui permet également de gérer les changements de charge rapides qui se produisent par exemple lorsque les dispositifs de communication mobiles passent du mode veille au mode transmission.
• Le multimètre 6,5digits intégré est l’outil de caractérisation idéal des cycles de consommation à grande dynamique, typique de l’IOT.

 High precision source and sink

Due to their high accuracy and fast load recovery time, the R&S®NGL200 power supply series is perfect for challenging applications. Their two-quadrant architecture allows them to function both as a source and a sink to simulate batteries and loads. Their short recovery times enable them to handle fast load changes that occur for example when mobile communications devices switch from sleep mode to transmit mode. 

Two quadrants: operates as source and sink

The two-quadrant architecture of the power supplies allows them to function both as a source and a sink and simulate batteries or loads. The power supply automatically switches from source mode 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.

Readings with up to 6 ½ digit resolution

With a resolution of up to 6 ½ digits when measuring voltage, current and power, the R&S®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.

High-resolution touchscreen

The large capacitive touchscreen is the central operating element for R&S®NGL200 power supplies. Lightly tapping a numerical value brings up a virtual keyboard to enter the desired value. Alternatively, the voltage, current and limits for the various protection functions can be set using the rotary knob. Functions that are used less frequently can be accessed and operated via menus.

With its very high resolution of 800 × 480 pixels, the display sets new standards for power supplies. The large high-resolution display makes it easy to read the voltage and current fields, even at great distances. A wide variety of additional information, such as power values or statistics, can also be displayed. Icons clearly show the status of the set protection or special functions.
