Features & benefits

All channels galvanically isolated and earth free

The circuitry in each channel is completely separated from the others with no connection to chassis ground. This makes combining the channels to drive bipolar circuitries that might need +12 V/–12 V easy and eliminates any ground problems in a complex DUT.

Driving a bipolar circuit

Combine channels to drive bipolar circuitry in complex DUTs that might need +12 V and –12 V without ground problems.

Parallel and serial operation

Because all channels are electrically equivalent, they can be combined in serial mode for higher voltages. Up to 96 V are possible with the R&S®NGE103B, up to 64 V with the R&S®NGE102B. Channels can be bundled for higher current in parallel mode. Up to 6 A are possible when two channels are combined. Using all three of the R&S®NGE103B channels, even 9 A is possible.

Parallel and serial operation

Parallel and serial operation

The output channels can be combined in serial or parallel for higher voltages or currents.

Protection functions

For each channel, users can separately set:

  • Maximum current (electronic fuse, overcurrent protection, OCP)
  • Maximum voltage (overvoltage protection, OVP)
  • Maximum power (overpower protection, OPP)
When a limit is reached, the output channel will automatically switch off and a message displayed. The overcurrent protection can be linked to other channels (FuseLink function). Here, the channel that exceeds the maximum current level and all linked channels are switched off.

If a limit is reached, the output channel will automatically switch off and a message will be displayed.

Color-coded 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 different operating conditions:

  • Active output is green when working in constant voltage mode and red when working in constant current mode
  • Inactive output is white. Whenever a channel is in setting mode, the number being set has a blue background.

The operating conditions are marked by colors

The operating conditions are marked by colors

Constant voltage is green, constant current red, inactive channels are white and a blue background indicates a channel in setting mode.


  • Front connectors with 4 mm safety binding posts
  • USB interface (virtual COM port and TMC class)
  • LAN interface (LXI) with integrated web server (R&S®NGE-K101 option) 
  • Wireless LAN, unique in class (R&S®NGE-K102 option)
  • Digital trigger in/out (4-bit) on the rear (R&S®NGE-K103 option)

Digital I/O
Open Lightbox

Digital I/O

Channel 1 of the optional digital I/O interface is used as a trigger input.
