2 Welcome to R&S NGU
The single source measure units are based on a classical transformer concept with lin-
ear regulators. This concept allows the instrument to achieve highest accuracy and
lowest residual ripple.
Multi-purpose protection functions are available which you can set separately, such as
overcurrent protection (OCP), overvoltage protection (OVP) and overpower protection
(OPP). If such a limit is reached, the affected output is automatically 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 temperature 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 during 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 devices in the event
when a trigger occurs.
The user manual contains description of the functionalities that the instrument pro-
vides. The latest version is available for download at the product homepage (http://
www.rohde-schwarz.com/product/ngu).

3.2 Ambient Conditions
The allowed operating temperature ranges from +5 °C to +40 °C (pollution category 2).
The maximum relative humidity (without condensation) is at 80 %.
During storage and transport, the temperature must be between -40 °C and +70 °C. In
case of condensation during transportation or storage, the instrument requires approxi-
mately two hours to dry and reach the appropriate temperature prior to operation. The
instrument is designed for use in a clean and dry indoor environment. Do not operate
with high dust and humidity levels, if danger of explosion exists or with aggressive
chemical agents.
Any operating position may be used; however adequate air circulation must be main-
tained. For continuous operation, a horizontal or inclined position (integrated stand) is
preferable.
Specifications with tolerance data apply after a warm-up period of at least 30 minutes
at a temperature of 23 °C (tolerance -3 °C / + 7 °C).
The heat produced inside the instrument is guided to the exterior via temperature-con-
trolled fan. Each channel has multiple temperature sensors which check the heat gen-
eration in the instrument and control the fan speed.
It is necessary to ensure that there is sufficient space around the instrument sides for
heat exchange. If the temperature inside the instrument increases more than the

Do not obstruct the ventilation holes!
3.3 Measurement Categories
This instrument is designed for supplying power-on circuits that are only indirectly con-
nected to the low voltage mains or not connected at all. The instrument is not intended
for measurements within the measurement categories II, III or IV; the maximum poten-
tial against earth generated by the user must not exceed 250 V peak in this application.
The following information refers solely to user safety. Other aspects, such as the maxi-
mum voltage, are described in the technical data and must also be observed.
The measurement categories refer to transients that are superimposed on the mains
voltage. Transients are short, very fast (steep) current and voltage variations which
may occur periodically and non-periodically. The level of potential transients increases
as the distance to the source of the low voltage installation decreases.
●Measurement CAT IV: Measurements at the source of the low voltage installations
(e.g. meters)
●Measurement CAT III: Measurements in building installations (e.g. power distribu-
tion installations, power switches, firmly installed sockets, firmly installed engines
etc.)
●Measurement CAT II: Measurements on circuits electronically directly connected to
the mains (e.g. household appliances, power tools, etc.)
●0 (instruments without measured measurement category): Other circuits that are
not connected directly to the mains
3.4 Mains Voltage
The instrument uses 50 Hz / 60 Hz mains voltages ranging from 100 VAC, 115 VAC or
230 VAC (tolerance ± 10 %). Mains voltage must be set correctly by removing the fuse
holder and rotating until the correct voltage appears through the window and reinstal-
ling the fuse holder. The input line fuse is accessible externally. Power socket and fuse
holder form a single unit.
You need to first disconnect the power cord from the connector before you can safely
replace the fuse (as long as the fuse holder is undamaged). Next, the fuse holder must
be pried out using a screwdriver. The starting point is a slot next to the contacts. The
fuse can then be forced out of its mounting and must be replaced with an identical fuse
(see information about the fuse type on the rear panel). The fuse holder is inserted
