3 Welcome to R&S NGL200
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 NGL200 power supply series feature galvanically isolated, floating over-
load and short-circuit proof outputs. The outputs can be connected in parallel and
serial to get higher voltages, thus making high currents available.
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, 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 NGL200 is protected with overtemperature protection
(OCP). This safey feature protects the R&S NGL200 from getting overheated,
when activated, the channel outputs are turned off.
The Arbitrary function allows a freely definable voltage and current sequences
with a timeframe as short as 10 ms. It allows you to vary the voltage or current
limit during a test sequence, for example to simulate different charging conditions
of a battery. With Ramp function, the R&S NGL200 provides the operating condi-
tion to simulate the continuous rise of the supply voltage within a defined time-
frame of 10 ms to 10 s.
All R&S NGL200 power supply series are equipped with a color LCD display (800
x 480 pixels). The R&S NGL200 comes with a USB and LAN (LXI) interface.
Equipped with a wireless LAN (WLAN) option, you can establish a network con-
nection wirelessly .
The digital I/O interfaces installed at the rear panel is activated with an option, it
provides a set of 4-bit digital interfaces that can be individually used as trigger
inputs or outputs.
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/ngl200).

4.1 Safety
This instrument was built in compliance with DIN EN 61010-1 (VDE 0411 part 1),
safety regulations for electrical instruments, control units and Iaboratory equip-
ment.
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.
Safety

Putting into Operation
R&S®NGL200
12Getting Started 1178.8720.02 ─ 02
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.
For safety reasons, the instrument may only be operated with authorized safety
sockets. The power cord 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 cord 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 as follows:
●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.
Safety

Putting into Operation
R&S®NGL200
13Getting Started 1178.8720.02 ─ 02
Prior to 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. If it is
necessary to set a different voltage, the power fuse of the product may have to be
changed accordingly.
4.2 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 plug must be inserted before signal circuits may be connected.
Use only the power cord included in the delivery package. See "Delivery
package" on page 15.
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 product may be operated only under the operating conditions and in the posi-
tions 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 4-1 for the general data on the instrument specification. For more infor-
mation, see the instrument datasheet (PN: 5216.1057.12).
