2Welcome 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 voltages 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 (
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.
Welcome to R&S NGL/NGM
, , ) blinks on the display. In the
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 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 provides. The latest version is available for download at the product homepage (http://

3.3Measurement Categories
This instrument is designed for supplying power on circuits that are only indirectly connected 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 potential 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 maximum voltage, are described in the technical data and must also be observed.
Important Notes
Mains Voltage
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 distribution 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
3.4Mains 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 reinstalling 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

R&S®NGL200/NGM200
Source and sink current
The R&S NGL/NGM power supply series are 2 quadrant power supplies which may
both source and sink current. When the voltage across the output terminal exceeds the
set voltage, current flows into the instrument. The default behavior "Auto" can be configured in output menu, see "Output mode"on page 46.
On the display, sink mode is shown as negative current.
4.3.1Setting the Output Voltage and Current
1. Press [Home] key.

Trying Out the Instrument
4. Confirm value with the unit key (V/mV or A/mA).
4.3.2Activating the Channels Output
The output voltages can be switched on or off regardless of the operating mode the
instrument is in.
To switch on or off channel output.
1. Select desired channel key ([Ch1] or [Ch2]) on the front panel.
2. Press [Output] key.
The R&S NGL/NGM outputs the set voltage level on the selected output channel
terminal.
Depending on the mode which the channels are operated in, the followings are
observed:
CR mode
CR mode is a special case of sink mode in which the instrument behaves like a constant resistor. Only in this mode, the respective channel keys and display font color in
the home window turns cyan.
In "normal" sink mode, the colors are the same as in source mode: green if the current
flowing into the R&S NGL/NGM is below the set current and red if the current is limited
to the set value. The only visible indication of sink mode is the change of the sign of
the current readout change to "Minus".

work
Risk of network failure
Before connecting the instrument to the network or configuring the network, consult
your network administrator. Errors may affect the entire network.
To establish a network connection, connect a commercial RJ-45 cable to the LAN port
of the instrument and to a PC or network switch.
Depending on the network capacities, the TCP/IP address information for the instrument can be obtained in different ways.
●
If the network supports dynamic TCP/IP configuration using the Dynamic Host
Configuration Protocol (DHCP), and a DHCP server is available, all address information can be assigned automatically.
●
Otherwise, the address must be set manually. Automatic Private IP Addressing
(APIPA) is not supported.
By default, the instrument is configured to use dynamic TCP/IP configuration and
obtain all address information automatically. This means that it is safe to establish a
physical connection to the LAN without any previous instrument configuration.
Risk of network errors
Connection errors can affect the entire network. If your network does not support
DHCP, or if you choose to disable dynamic TCP/IP configuration, you must assign valid
address information before connecting the instrument to the LAN. Contact your network administrator to obtain a valid IP address.
