High-speed accuracy

R&S®NGM200 DC power supplies have high accuracy and fast load recovery times. Their two-quadrant architecture allows these DC power supplies to function both as a source and a sink to simulate batteries and loads. Short recovery times let the R&S®NGM200 handle fast load changes when mobile communications devices switch between sleep and transmit modes. High-speed data acquisition and convenient battery simulation widen the range of applications to:
- battery tests
- simulation of voltage drops
- power consumption test
- supplying sensitive designs
Choose the power supply you need by selecting the base unit and all the necessary options in our online configurator. It is easy, fully price transparent and ensures fast processing of your order request through our wide network of distribution partners. Click "Configure and quote" to start configuration.

Features & benefits

Battery simulation

with the 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 the 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.

**Battery simulation** - The main parameters for characterizing the condition of a battery are summarized in one display.

High-speed acquisition

FastLog function

R&S®NGM200 power supplies have the high-speed FastLog function to capture voltage and current measurement results. This data can be stored on an external USB storage device or 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. The two-channel R&S®NGM202 can run data acquisition on both channels in parallel. The high-speed acquisition can even detect the minimum/maximum values for spikes in the microsecond range that slower instruments cannot.

Digital voltmeter function

with R&S®NGM-K104

Like other power supplies, R&S®NGM200 instruments measure voltage supplied to the DUT. The R&S®NGM-K104 option activates a port allowing the internal digital voltmeter to be connected to any other point in a customer’s circuit. An additional digital multimeter is often not necessary.

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

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 supply series is ideal for characterizing devices with low standby power consumption and high current in full load operation. Two voltage measurement ranges and four ranges to measure current provide high accuracy and resolution 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 for such DUTs must handle 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, R&S®NGM200 power supplies have 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 supply line interference. To supply interference-free voltage to sensitive DUTs, power supplies must provide extremely stable output voltage and current. All forms of ripple and noise must be avoided. 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 power supply architecture can function both as a source and a sink to 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.
