Rohde & Schwarz NGU401 (3639.3763.03)

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 NGU401 can supply positive or negative voltages or currents and can act as a source or sink in both polarities.

High Speed Data Acquisition

(FastLog function)

The 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.

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 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.

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 behaviour from the leads and capacitance.

In high-capacitance mode, 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.
