Welcome to R&S NGL/NGM
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 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 (
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.
, , ) blinks
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

Switching On the Instrument
2. Connect the power cable to the socket outlet.
3. Press [Power] key on the front panel.
The instrument performs a system check, boots the operating system, and
starts the R&S NGL/NGM firmware.
By default, all output channels are turned off when the instrument is switched on
to prevent connected loads from being damaged unintentionally.
During startup, the R&S NGL/NGM is loaded with the last saved instrument settings from internal memory. See "Store and Recall" in the User Manual.
To switch off instrument:
1. Press [Power] key.
All current settings are saved to internal memory and the firmware shuts
down.

This chapter describes some basic functions that you can perform with the
R&S NGL/NGM.
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 section "Output mode" in the User Manual.
On the display, sink mode is shown as negative current.
5.1 Setting the Output Voltage and Current
1. Press [Home] key.
The R&S NGL/NGM displays the home window.
2. Select voltage or current parameter in the home window.
The R&S NGL/NGM displays an on-screen keypad to set the value.
3. Enter the required value.
4. Confirm value with the unit key (V/mV or A/mA).
5.2 Activating 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.

Activating the Channels Output
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".

Maintenance
6 Maintenance
Before cleaning the instrument, ensure that it has been switched off and the
power cable is disconnected.
Clean the outer case of the instrument at regular intervals, using a soft, lint-free
dust cloth.
Instrument damage caused by cleaning agents
Use a dry, lint-free cloth to clean the product. When cleaning, keep in mind
that the casing is not waterproof. Do not use any liquids for cleaning.
Cleaning agents, solvents (thinners, acetone), acids and bases can damage the front panel labeling, plastic parts and display.
The display may only be cleaned with an appropriate glass cleaner. Rub the display with a dry, clean and lint-free cloth. Do not allow cleaning fluid to enter the
instrument.
