Key facts

  • Two/four quadrants: operates as source and sink
  • High speed data acquisition (FastLog function)
  • Voltage priority and current priority mode
  • High-capacitance mode
  • Intuitive, price-transparent online product configurator

The top-class in supplying power

Their extremely high accuracy and fast load recovery times make R&S®NGU source measure units (SMU) perfect for challenging applications, such as:
- battery and power consumption tests
- supplying wireless devices with power
- simulation of voltage drops
A special ammeter design is used to precisely measure current drains from nA to A in one pass – no need to make multiple measurement sweeps. The short recovery times enable the instruments to handle fast load changes when mobile communications devices switch from sleep mode to transmit mode. Every detail is detected down to 2 μs resolution with high speed data acquisition. R&S®NGU source measure units have two- or four-quadrant architecture to function both as a source and a sink.
Configure your own R&S®NGU SMU with our online configurator tool and benefit from full price transparency, ease of configuration along with fast processing and shipment through an authorized distribution partner of your choice

Features & benefits

Two/four quadrants: operates as source and sink

Simulates batteries or loads

The two/four-quadrant architecture of these source measure units allows them to function both as a source and a sink to simulate batteries or loads. The SMU automatically switches from source mode to sink mode as soon as the externally applied voltage exceeds the set nominal voltage. With its four-quadrant architecture, the R&S®NGU401 can supply positive or negative voltages or currents and can act as a source or sink in both polarities.

R&S®NGU supplies positive or negative voltage in source or sink mode.

High speed data acquisition

FastLog function

The R&S®NGU source measure units offer the 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.

FastLog high speed data acquisition

The FastLog function follows voltage/current variations with a resolution of up to 2 μs.

Voltage priority and current priority mode

Optimized for voltage/current regulation

In voltage priority mode, fast voltage regulation provides short recovery times of less than 30 μs. Current regulation is designed to be somewhat slower to avoid oscillation. When precise and quick current regulation is desired, the R&S®NGU source measure units can be operated in current priority mode. Optimized for fast current regulation (load recovery time < 50 μs), this mode allows tasks such as LED testing, which are sensitive to even short current spikes.

Voltage/current priority mode
Open Lightbox

Voltage/current priority mode

The standard mode provides fast voltage regulation with the risk of current overshoots. The special mode has fast and risk-free current regulation.

High-capacitance mode

Compensate capacitors

Quite often in a typical measurement configuration, there is capacitance at the input of the DUT. Connecting the power supply with leads causes low pass behavior from the leads and capacitance. In high-capacitance mode, R&S®NGU source measure units compensate for the capacitance and display the current directly at the DUT.

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 be able to handle load changes from a few nA to the ampere range without creating voltage drops or overshoots.

Optimized load recovery time

Optimized load recovery time

Power supplies often respond to load changes with overshoot and slow recovery times. The R&S®NGU source measure units have recovery times of < 30 μs.
