4 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 vol-
tages 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 ( , , ) blinks
on the display. In the 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 bat-
tery. 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
