Thanks to their high accuracy and fast load recovery time, the R&S NGM200 power supplies are 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.
High-speed data acquisition and convenient battery simulation widen the range of applications.
Battery Simulator Function
When battery-operated devices have to be optimized for lifecycle, the discharging behavior of the used battery type needs to be considered.
The battery simulator function makes it possible to simulate the real battery output performance. Testing can be based on a selected battery model, while battery capacity, SoC and Voc can be set to any state to test the device under specific circumstances
Easy Operation
The high-resolution capacitive touchscreen is the central operating element for the R&S NGM200 power supplies. Icons clearly show the status of set protection or special functions.
When the power supply is in constant voltage mode, the numbers and the keys light up green. Red is used for constant current mode. The Output key lights up blue to indicate that the channels are switched on (active).
Readings with up to 6½ digit resolution
With a resolution of up to 6½ digits when measuring voltage, current and power, the R&S NGM200 power supplies are perfect for measurements on devices that have low power consumption in standby mode and high current in full load operation.
Two voltage measurement ranges and four current measurement ranges provide a high accuracy and resolutions down to 1 µV/10 nA
