Description
Start with the power budget, because it shapes every test on this unit. The Rohde & Schwarz NGU201 SMU is a source measure unit (SMU). One channel sources power, sinks power and measures what flows. It tops out at 60 W, so voltage and current trade against each other.
Reading the 60 W limit
The channel covers 0 V to 20 V. Also, current reaches 8 A at 6 V or below. However, above 6 V the ceiling drops to 3 A. Therefore you cannot ask for 20 V and 8 A together. Multiply voltage by current for each load, then leave margin for startup surges.
Two-quadrant operation means the unit can sink current as well. That helps because a battery or another source can push energy back at the channel. Check the sink limits in the operating manual before you connect anything.
Logging, priority modes and sensing
FastLog captures up to 500 ksample/s, so short current spikes still show in the record. You can run in voltage priority or current priority, depending on whether the load or the limit should win. Remote sensing then measures voltage at the device, so lead drop stays out of the result. USB and LAN link the unit to a control computer.
Two functions need options: battery simulation and the digital voltmeter. Ask for both by name, because the base unit does not include them.
Jobs for a Rohde & Schwarz NGU201 SMU
- Power up a board and watch each supply rail.
- Profile the current of a low-power device across its states.
- Next, simulate a battery once the option is installed.
- Run source-measure sweeps on small components.
For example, a firmware team can log current through sleep and wake cycles, while a production cell checks startup current on every board.
Buy it or rent it
Lost in HCM lists the NGU201 for rental and for sale, and it arranges service on request. So a defined project or a peak in R&D load suits a rental. However, a lab that uses the unit every week may prefer to own one. Price and availability come only from the quote.

Rohde & Schwarz NGU201 SMU questions
Can it deliver 8 A at 12 V?
No. Above 6 V the current rating is up to 3 A, and the channel stops at 60 W.
Can it sink current like a load?
Yes, within its limits. Two-quadrant operation lets it source or sink, so read the manual before you connect a battery.
