2 Welcome to R&S NGL/NGM
The one or two-channel power supply series are based on a classical transformer
concept with linear regulators. This concept allows the instrument to achieve
highest accuracy and lowest residual ripple.
The R&S NGL/NGM power supply series feature galvanically isolated, floating
overload and short-circuit proof outputs. When multiple channels are connected in
parallel, higher currents can be achieved. When connected in serial, higher vol-
tages are achievable.
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 temperature 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 bat-
tery. 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
provides. The latest version is available for download at the product homepage

Risk of instrument damage during operation
An unsuitable operating site or test setup can cause damage to the instru-
ment and the connected devices. Ensure the following operating conditions
before you switch on the instrument:
●The instrument is dry and shows no sign of condensation
●The instrument is positioned as described in Chapter 3.4.1, "Bench
Operation", on page 14
●The ambient temperature does not exceed the range specified in the
data sheet
●Signal levels at the input connectors are all within the specified ranges
●Signal outputs are correctly connected and not overloaded
EMI impact on measurement results
Electromagnetic interference (EMI) may affect the measurement results.
To suppress the generated EMI:
●Use suitable shielded cables of high quality, for example, LAN cables
●Note the EMC classification in the data sheet
3.1 Safety
This instrument was built in compliance with DIN EN 61010-1, safety regulations
for electrical instruments, control units and Iaboratory equipment.
It has been tested and shipped from the plant in safe condition. It is also in com-
pliance with the regulations of the European standard EN 61010-1 and the inter-
national standard IEC 61010-1.
To maintain this condition and ensure safe operation, you must observe all
instructions and warnings given in this user manual. Casing, chassis and all mea-
suring ports are connected to a protective earth conductor. The instrument is
designed in compliance with the regulations of protection class I.
Safety

Putting into Operation
R&S®NGL200/NGM200
11Getting Started 1178.8720.02 ─ 05
For safety reasons, the instrument may only be operated with authorized safety
sockets. The power cable must be plugged in before signal circuits may be con-
nected.
Never use the product if the power cable is damaged. Check regularly if the
power cables are in perfect condition. Choose suitable protective measures and
installation types to ensure that the power cable cannot be damaged and that no
harm is caused by tripping hazards or from electric shock, for instance.
Risk of electric shock
It is prohibited to disconnect the earthed protective connection inside or out-
side of the instrument!
If it is assumed that a safe operation is no longer possible, the instrument must be
shut down and secured against any unintended operation.
Safe operation can no longer be assumed when:
●Instrument shows visible damage
●Instrument includes loose parts
●Instrument no longer functions properly
– After an extended period of storage under unfavorable conditions (e.g. out-
doors or in damp rooms)
– After rough handling during transport (e.g. packaging that does not meet
the minimum requirements by post office, railway or forwarding agency)
Exceeding the low voltage protection
Use insulated wires and not bare wires for the terminal connection.
It is assumed that only qualified and trained personnel service the power
supplies and the connected loads.
Before switching on the product, it must be ensured that the nominal voltage set-
ting on the product matches the nominal voltage of the AC supply network.

3.2 Intended Operation
The instrument is intended only for use by personnel familiar with the potential
risks of measuring electrical quantities.
For safety reasons, the instrument may only be connected to properly installed
wall outlets. Separating the ground is prohibited.
The power cable must be inserted before signal circuits may be connected.
Use only the power cable included in the delivery package. See "Delivery
package" on page 14.
Before each measurement, measuring cables must be inspected for dam-
age and replaced if necessary. Damaged or worn components can damage
the instrument or cause injury.
The instrument may be operated only under the operating conditions and in the
positions specified by the manufacturer, without the product's ventilation being
obstructed. If the manufacturer’s specifications are not observed, this can result
in electric shock, fire and/or serious personal injury, and in some cases, death.
Applicable local or national safety regulations and rules for the prevention of acci-
dents must be observed in all work performed.
The instrument is designed for use in the following sectors: Industrial, residential,
business and commercial areas and small businesses.
The instrument is designed for indoor use only. Before each measurement, you
need to verify at a known source if the instrument functions properly.
To disconnect from the mains, unplug the IEC socket on the back panel.
See Table 3-1 for the general data on the instrument specification. For more infor-
mation, see the instrument datasheet (P/N: 5216.1057.32).
