Welcome to R&S
NGL200
The one or two-channel power supply series are based on a classical transformer con-
cept with linear regulators. This concept allows the instrument to achieve highest accu-
racy 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 con-
tinuous 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 wire-
lessly .
The digital I/O interfaces installed at the rear panel is activated with an option, it pro-
vides 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 pro-
vides. The latest version is available for download at the product homepage (
