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 ( case of two-channel power supply (R&S NGL202, R&S 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 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://

3.2 Ambient conditions

The allowed operating temperature ranges from +5 °C to +40 °C (pollution category 2). The maximum relative humidity (without condensation) is at 80 %.
During storage and transport, the temperature must be between -40 °C and +70 °C. In case of condensation during transportation or storage, the instrument requires approxi­mately two hours to dry and reach the appropriate temperature prior to operation. The instrument is designed for use in a clean and dry indoor environment. Do not operate with high dust and humidity levels, if danger of explosion exists or with aggressive chemical agents.
Any operating position may be used; however adequate air circulation must be main­tained. For continuous operation, a horizontal or inclined position (integrated stand) is preferable.
Specifications with tolerance data apply after a warm-up period of at least 30 minutes at a temperature of 23 °C (tolerance -3 °C / + 7 °C).
The heat produced inside the instrument is guided to the exterior via temperature-con­trolled fan. Each channel has multiple temperature sensors which check the heat gen­eration in the instrument and control the fan speed.
It is necessary to ensure that there is sufficient space around the instrument sides for heat exchange. If the temperature inside the instrument increases more than the

Do not obstruct the ventilation holes!

3.3 Measurement 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

3.4 Mains 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
15User Manual 1178.8736.02 ─ 10
R&S®NGL200/NGM200
against the spring pressure until it locks into place. The use of mended fuses or short circuiting the fuse holder is prohibited. Resulting damages are not covered by the war­ranty.
Safe operation
If the instrument is not in use, it must be switched off at the mains switch for safety rea­sons.

4.3 Trying out the instrument

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 Chapter 6.2.3.4, "Output mode", on page 52.
On the display, sink mode is shown as negative current. See also "CR mode" on page 29.

4.3.1 Setting the output voltage and current

Getting started
Trying out the instrument
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).
See "Source and sink current" on page 28 for more information on the operating modes supported in different models.

4.3.2 Activating the channels output

The output voltages can be switched on or off regardless of the instrument's operating mode.
To switch on or off channel output.
1. For the two-channel models, 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 output channel terminal.
Depending on the operating mode which the channels are operated in, the following are observed:
28User Manual 1178.8736.02 ─ 10
R&S®NGL200/NGM200
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 sign of the current readout to "Minus".
