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 (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 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://
www.rohde-schwarz.com/product/ngl200 for R&S NGL and http://www.rohde­schwarz.com/product/ngm200 for R&S NGM) .

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 to more than

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
11User Manual 1178.8736.02 ─ 05

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.
