Rohde & Schwarz’s Debut in SMU Market with R&S NGU

Rohde and Schwarz has made their debut in the source measure units (SMU) market with two new models in the R&S NGU series of high-precision SMUs.

Rohde and SchwarzThe steady extension of the Rohde & Schwarz portfolio of specialty power supplies continues with the first two models in the R&S NGU series of high-precision SMUs. The instruments’ innovative current feedback amplifier technology provides both maximum sensitivity and accuracy to reliably measure currents from nA to A in a single sweep.

To handle rapidly changing load conditions typical of battery-powered communications devices switching between sleep and transmit modes, the R&S NGU features an optimized control loop load providing a best-in-class recovery time of under 30 μs with minimum overshoot.

The R&S NGU SMUs include six current ranges from 10 µA with 100 pA resolution to 10 A with 10 µA resolution. For all ranges, accuracy up to 0.025 % is achieved. Voltage is measured with 10 µV resolution in the 20 V range and 1 µV resolution in the 6 V range.

For the typical measurement problem of capacitance at the input to the device under test, the R&S NGU features a variable capacitance mode adjustable in steps from 1 µF to 470 µF, compensating the capacitance, so that the current is displayed as if it was measured directly at the device under test. Devices up to 20 V, 8 A, and 60 W are all supported.

The four-quadrant R&S NGU401 is the specialist for semiconductor testing. It provides source measurements for any equipment requiring source and sinks voltages in the range from –20 V to +20 V. In addition to the voltage regulation mode of power supplies, the R&S NGU includes a fast current regulation mode to avoid damaging current-sensitive devices under tests, such as LEDs or other semiconductors.

An external arbitrary waveform source connector turns the R&S NGU401 into an AC source and makes it possible to simulate glitches or unstable power supplies of up to 1 kHz.

In addition to the dedicated source measurement features, the R&S NGU series also includes elaborate features common to all specialty power supplies from Rohde & Schwarz.

The new R&S NGU201 and R&S NGU401 source measure units are part of the R&S Essentials portfolio and are now available from Rohde & Schwarz and selected distribution partners.
