R&S®NGM200 Power Supply Series High-speed accuracy Data Sheet | Version 01.00 year NGM200_dat_en_3609-1685-32_v0100.indd 1 22.05.
R&S®NGM200 Power Supply Series At a glance 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.

Technology for challenging tasks The R&S®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. Fast load regulation Consumer electronics such as mobile phones and IoT devices require very little power in sleep mode.
Readings with up to 6 ½ digit resolution Output stage isolated with relays With a resolution of up to 6 ½ digits when measuring voltage, current and power, the R&S®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/10 nA.
Variable output impedance High-speed acquisition (FastLog functionality) A power supply should have an output impedance as low as possible to suppress loading effects on the DUT. However, there are applications where certain battery types need to be simulated in a controlled manner or where it is necessary to simulate the increase in internal impedance as the battery discharges. The R&S®NGM200 power supplies support these applications due to their adjustable output impedance range.
Protection functions to safeguard instrument and DUT The R&S®NGM200 power supplies provide protection functions to make sure the DUT and the power supply are not damaged in the event of a fault. The output channels are protected against overload and short circuits. The maximum voltage, current and power can be set separately for each channel. When a channel reaches the set limit, it is automatically switched off and a message is displayed.
Battery simulation Battery models Real batteries show different characteristics depending on the type of battery and its charging condition. Capacity, open circuit voltage (Voc) and equivalent series resistance (ESR) are important battery characteristics that depend on its state of charge (SoC). The optional R&S®NGM-K106 functionality allows users to simulate the behavior of batteries under different charging conditions, e.g. when powering a DUT.
Easy operation High-resolution touchscreen The large capacitive touchscreen is the central operating element for R&S®NGM200 power supplies. Lightly tapping a numerical value will display a virtual keyboard to input the desired value. Alternatively, the voltage, current and limits for the various protection functions can be set using the rotary knob. Functions that are less frequently used can be accessed and operated via menus.
Color coding of operating modes Colors are used to indicate the different modes. For example, active channels in constant voltage mode light up green, while red is used for constant current mode. When the power supply is in constant resistance mode, the numbers are displayed in cyan. Each of the R&S®NGM202 channels can be selected individually using the channel keys. The Output key is used to switch the selected channels on or off. The key lights up blue when it is switched on.
Ideal for use in labs and test systems Digital inputs and outputs are optionally available. They can be used as trigger/inhibit inputs and control/fault outputs. The hardware of the R&S®NGM-K103 option is pre installed. The function can be activated using a keycode (to be ordered separately). Full remote capabilities Tailored for use in labs and system racks The R&S®NGM200 power supplies are the right choice for challenging applications.
