High-speed accuracy

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 simulation

with R&S®NGM-K106

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.

High-speed acquisition

FastLog functionality

The R&S®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 (R&S®NGM-K104) can be logged with 500 ksample/s. Using the two-channel R&S®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.

**FastLog functionality** - The FastLog functionality follows voltage/current variations with a resolution of up to 2 µs. It detects spikes that would be overseen by slower instruments.

Digital voltmeter functionality

with R&S®NGM-K104

Like other power supplies, the R&S®NGM200 instruments measure the voltage supplied to the DUT. In addition, the R&S®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.

**Digital voltmeter functionality (DVM)** - The internal digital voltmeter of the R&S®NGM200 power supplies can optionally be used to measure at any point in the customer’s circuitry.

6 ½ digit resolution

replaces an additional DMM

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 current measure ranges provide high accuracy and resolutions down to 1 µV/10 nA.

**6 ½ digit resolution in V/I metering** - The measured currents and voltages are displayed with 6 ½ digit resolution.

Fast load regulation

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 µA to the ampere range without creating voltage drops or overshoots.

**Exceptionally fast load recovery time** - Power supplies usually respond to abrupt load changes with overshoot and slow recovery times. Thanks to specially optimized control circuits, the R&S®NGM200 power supplies achieve recovery times of < 30 µs.

Minimum residual ripple and low noise

< 500 𝛍V (RMS) / < 2 mV (peak-to-peak)

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 R&S®NGM200 power supplies have linear regulation and are ideal for sensitive DUTs.

Two quadrant operation

operated 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.

**Source and sink mode** - In the example, channel 2 is operating as a load. This is indicated by a negative current reading.
