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 overload 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 condition to simulate the continuous rise of the supply voltage within a defined timeframe 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 connection 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).

The instrument performs a system check, boots the operating system, and
starts the R&S NGL200 firmware.
By default, all output channels are turned off when the instrument is switched on
to prevent connected loads from being damaged unintentionally.
To switch off instrument:
1. Press [Power] key.
All current settings are saved to internal memory and the firmware shutdown.
2. Disconnect the AC power cable from the AC power supply.

6 Trying Out the Instrument
This chapter describes some basic functions that you can perform with the
R&S NGL200.
Source and sink current
The R&S NGL200 series are 2 quadrant power supplies which may both
source and sink current. This function needs no separate configuration or
mode switching. As soon as the voltage across the output terminal exceeds
the set voltage, current flows into the instrument. This is an intended feature
and it is safe.
On the display, sink mode is shown as negative current.
6.1 Setting the Output Voltage and Current
1. Press [Home] key.
The R&S NGL200 displays the home window.
2. Select voltage or current parameter in the home window
The R&S NGL200 displays an on-screen keypad to set the value.
3. Enter the required value.
4. Confirm value with the unit key (for voltage - V or mV, for current A or mA).
6.2 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.

The R&S NGL200 output 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 NGL200 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".

Operating mode
Green Constant voltage mode (CV)
Red Constant current mode (CC)
Cyan Constant resistance mode (CR)
Note: Instrument is operated in sink mode
and "Constant Resistance" is activated.
Also, the operating symbol mode (CV, CC or CR) is displayed at the channel status bar of the respective channel.

7 Maintenance
Before cleaning the instrument, ensure that it has been switched off and 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
Cleaning agents contain substances that may damage the instrument. For
example, cleaning agents that contain a solvent may damage the front
panel labeling, plastic parts, or the display.
Never use cleaning agents such as solvents (thinners, acetone, etc.), acids,
bases, or other substances.
The display may only be cleaned with an appropriate glass cleaner. Rub the display down with a dry, clean and lint-free cloth. Do not allow cleaning fluid to enter
the instrument.
