NGE100 Power Supply Series
The R&S NGE100 power supply series consists of robust, high-performance, affordable instruments. They offer high efficiency combined with low ripple plus a variety of comfort functions that are not usually found in this class of power supplies.
The R&S NGE100 power supply series consists of the R&S NGE102 two-channel power supply and the R&S NGE103 three-channel power supply. Both instruments provide up to 33.6 W output power per channel.

Unlike most power supplies in this class, the R&S NGE100 power supplies feature 100 % electrically equivalent output channels. All outputs are earth-free and short-circuit-proof. The output channels can be combined in serial or in parallel to achieve higher voltages or higher currents (up to 96 V/9 A using all three channels of the R&S NGE103).
All basic functions of the R&S NGE100 power supplies can be operated via direct keys on the front panel. The rotary knob plays the central role in adjusting the voltage and current and setting the limits for the multi-purpose protection functions. The operating conditions of all channels are displayed on the screen simultaneously. Active channels are indicated by the illuminated channel key. Active outputs are shown in green when working in constant voltage mode and in red when working in constant current mode. Inactive outputs are displayed in yellow.
To safeguard the instrument and the device under test (DUT), the R&S NGE100 power supplies provide a variety of protection functions. For each channel, users can separately set the maximum current (electronic fuse, over-current protection, OCP), the maximum voltage (over-voltage protection, OVP) or the maximum power (overpower protection, OPP). If such a limit is reached, the affected output channel will be switched off. Over-temperature protection (OTP) prevents overheating of the instrument
In industrial applications, power supplies are often installed in 19" racks. The R&S HZC95 rackmount kit allows the power supplies to be mounted in racks, including in combination with R&S HMC test instruments. The R&S NGE100 power supplies can be remotely controlled via USB or optionally via Ethernet or even via wireless LAN.
Easy Operation
Comfort features for special applications
Some applications require that the user vary the voltage or the current during a test sequence, for example to simulate different charging conditions of a battery. Here, the EasyArb function is a comfortable solution that is not usually found in basic class power supplies. EasyArb al- lows the user to program time/voltage or time/current sequences, either manually via the user interface, or via the external interfaces.
Sometimes test sequences have to simulate operating conditions where the abrupt rise of the supply voltage has to be avoided. The EasyRamp function of the R&S NGE100 power supply series offers the solution. The output voltage can be increased continuously within a 10 ms to 10 s time frame. Of course the EasyArb and EasyRamp functions can both be controlled manually or via remote control. |
Straightforward operation
All basic R&S NGE100 power supply functions can be op- erated via direct keys on the front panel – no need to ma- neuver through a jungle of menus. Just press the "Voltage"key, select an output channel and use the rotary knob or the arrow keys to adjust the desired voltage in steps down to 10 mV. A constant output current can be similary set in steps down to 1 mA.
If channels need to be operated simultaneously, for ex- ample to increase the voltage of a device from ±12 V to ±15 V, press the "Track" key, select the two channels for positive and negative voltage and adjust the two voltages. The rotary knob will adjust the two voltages symmetrically. Activating or deactivating the electronic fuses is just as easy – by simply pressing one key on the front panel. |

Executed Protection functions are always Displayed on the screen

Color-coding of operating conditions
All operating conditions are shown clearly on the 3.5"
QVGA display (320 × 240 pixel), including the output power and the status of any protective functions. Colors indicate the different operating conditions:
- Active outputs are shown in green when working in constant voltage mode and in red when working in constant current mode
- Inactive outputs are displayed in yellow. Whenever a channel is in the setting mode, the display color changes to blue
|
Tracking and link functions
The separate output channels can function as individual power supplies, but demonstrate their versatility when combined. Running in parallel, higher currents can be achieved; serial connected channels yield higher voltages. The tracking function allows the user to vary the voltage on all channels in parallel for very convenient operation.
The link function of the electronic fuse makes the instrument even more versatile. Users can set up the power supply so that all channels are switched off if one channel hits its limit. Or it can be set up to leave one channel working, for example to keep the fan powered to cool down the DUT. The status of fuses and all other protection functions is always shown on the display. |
The different operating conditions are marked by colors: constant voltage operation is indicated in green, constant current operation in red, inactive channels are shown in yellow, blue indicates that the channel is in setting mode.

Five memory keys to save/recall instrument settings
Frequently used instrument settings can easily be stored/ recalled via five memory keys on the front panel.
Connectivity - Everything you need
Front connectors with 4 mm screw-type sockets
The output connectors on the front of the R&S NGE100 power supplies can hold 4 mm banana plugs or they can clamp stripped cables as very often seen in educational applications. The design of the connectors is robust enough to survive generations of students.
USB interface (virtual COM port and TMC class)
Via the USB interface, the instrument can be controlled from external PCs.

In addition to the standard USB connector, the R&S NGE100 power supplies offer an optional Ethernet interface, which can be activated by the customer using a key code that has to be ordered separately. This option allows the user to remotely control all instrument parameters. A fixed IP address can be used, or, alternatively, DHCP function might be used to allocate dynamic IP addresses. The Ethernet function offers a web server that can be used by standard web browsers (i.e. Internet Explorer).
The R&S NGE100 power supply series is LXI certified in line with version 1.4 (LXI Core 2011).
Wireless LAN, unique in this class (R&S NGE-K102 option) |

An alternative to remotely controlling the R&S NGE100 power supply series is to use the wireless LAN interface. Activated by a key code (option to be ordered separately), the wireless LAN module supports the CLIENT mode, meaning the instruments automatically connect to a network. Other power supplies or other test instruments can also be connected. Using a browser, all connected instruments can be operated via the web. In a typical student class, it enables the teacher to control all of the students’ instruments or to set them to defined start conditions.
Note: The wireless LAN functionality is not available in all regions due to country-specific regulations. |
Channel 1 of the optional digital I/O interface is used as a trigger input.

Digital trigger in/out (4-bit) on the rear (R&S NGE-K103 option)
Another option for the R&S NGE100 power supply series is a set of a 4-bit digital in/out interfaces that can be individually used as trigger inputs or outputs. Similar to the other options, the hardware of the R&S NGE-K103 option is already installed, the functionality is activated with a key code.
