2 Welcome to R&S NGL/NGM
The one or two-channel power supply series are based on a classical transformer con-
cept with linear regulators. This concept allows the instrument to achieve highest accu-
racy and lowest residual ripple.
The R&S NGL/NGM power supply series feature galvanically isolated, floating over-
load and short-circuit proof outputs. When multiple channels are connected in parallel,
higher currents can be achieved. When connected in serial, higher voltages are ach-
ievable.
Multi-purpose protection functions are available for each channel 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 channel is
automatically turned off and an indicator icon ( , , ) blinks on the display. In the
case of two-channel power supply (NGL202, NGM202), the overcurrent protection can
be linked to the other channel. In this case, the linked channel is turned off when the
other channel reaches a limit.
Additionally, the R&S NGL/NGM is protected with overtemperature protection (OTP).
This safety feature protects the R&S NGL/NGM from overheating. When the tempera-
ture in the power supply exceeds the OTP limit, the channel outputs are automatically
cut off.
The Arbitrary function allows a freely definable voltage and current sequences with a
timeframe as short as 1 ms. 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 NGL/NGM provides the operating condition to ramp up the
supply voltage within a defined timeframe of 10 ms to 10 s.
All R&S NGL/NGM power supplies are equipped with a color TFT display (800 pixels x
480 pixels) and enhanced with touch input capability. The R&S NGL/NGM comes with
a USB and LAN (LXI) interface. Equipped with a wireless LAN (WLAN) option, you can
establish a network connection wirelessly.
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 power supply, 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/ngl200 for R&S NGL and http://www.rohde-
schwarz.com/product/ngm200 for R&S NGM) .

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 to more than

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
