2 Welcome to R&S NGU
The single source measure units are based on a classical transformer concept
with linear regulators. This concept allows the instrument to achieve highest accu-
racy and lowest residual ripple.
Multi-purpose protection functions are available which you can set separately,
such as overcurrent protection (OCP), overvoltage protection (OVP) and over-
power protection (OPP). If such a limit is reached, the affected output is automati-
cally turned off and an indicator icon ( , , ) blinks on the display.
Additionally, the R&S NGU is protected with overtemperature protection (OTP).
This safety feature protects the R&S NGU from overheating. When the tempera-
ture in the source measure unit exceeds the OTP limit, the output is automatically
cut off.
The Arbitrary function allows a freely definable voltage and current sequences
with a timeframe as short as 100 µs. It allows varying the voltage or current dur-
ing a test sequence, for example to simulate different charging conditions of a
battery. With "Ramp" function, the R&S NGU provides the operating condition to
ramp up the supply voltage within a defined timeframe of 10 ms to 10 s.
All R&S NGU source measure units are equipped with a color TFT display (800
pixels x 480 pixels) and enhanced with touch input capability. The R&S NGU can
be remotely controlled via USB, LAN (LXI) interface and optional GPIB option.
The digital I/O interface installed at the rear panel is activated with an option, it
allows a single trigger-in signal to control multi trigger-out signals on the source
measure unit, providing many possibilities to control outputs and associated devi-
ces in the event when a trigger occurs.
The user manual contains description of the functionalities that the instrument
provides. The latest version is available for download at the product homepage
(http://www.rohde-schwarz.com/product/ngu).
