4 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).

5 Putting into operation
This chapter describes how to set up the R&S NGU source measure units for the
first time.
Risk of injury due to disregarding safety information
Observe the information on appropriate operating conditions provided in the
data sheet to prevent personal injury or damage to the instrument. Read
and observe the basic safety instructions provided with the instrument, in
addition to the safety instructions in the following sections. In particular:
●Do not open the instrument casing.
Risk of instrument damage due to inappropriate operating conditions
Specific operating conditions are required to ensure accurate measure-
ments and to avoid damage to the instrument. Observe the information on
appropriate operating conditions provided in the basic safety instructions
and the instrument's data sheet.
Instrument damage caused by electrostatic discharge
Electrostatic discharge (ESD) can damage the electronic components of the
instrument and the device under test (DUT). Electrostatic discharge is most
likely to occur when you connect or disconnect a DUT or test fixture to the
instrument's test ports. To prevent electrostatic discharge, use a wrist strap
and cord and connect yourself to the ground, or use a conductive floor mat
and heel strap combination.
