3 Welcome to R&S NGP800
The two or four-channel power supply series are based on a primary switched-
mode regulator with power factor correction. This concept allows the instrument
to achieve highest accuracy and lowest residual ripple.
The R&S NGP800 power supply series feature galvanically isolated, overload and
short-circuit proof outputs. The outputs can be connected in parallel and serial to
achieve higher currents or voltages.
Multi-purpose protection functions, such as overcurrent protection (OCP), over-
voltage protection (OVP) and overpower protection (OPP) can be set separately
for each channel. If the set limit is reached, the affected output channel is auto-
matically turned off and an indicator icon ( , , ) flashes on the display. The
overcurrent protection can also be linked to the other channels. If the current
exceeds the limit on the affected channel, all linked channels will be switched off.
The R&S NGP800 power supply series are also protected from overheating. Each
channel is equipped with a temperature sensor that monitors the channel operat-
ing temperature for controlling the fan speed and overtemperature protection. If
the safe limit is exceeded, the output of the affected channel is switched off. The
channel must cool down to a defined threshold before the output can be switched
on again. Operations of the other channels are not affected. Also, the actual oper-
ating speed of the fans is monitored. If a fan is not running, e.g. rotor locked con-
dition, all the outputs will be switched off to prevent overheating.
The R&S QuickArb function allows freely definable voltage and current sequen-
ces with a timeframe as short as 1 ms, e.g. to simulate different charging condi-
tions of a battery. The voltage and current points can also be grouped in different
blocks which can be sequenced and repeated independently to achieve a flexible
arbitrary function generation.
With the R&S EasyRamp function, the R&S NGP800 power supply provides the
operating condition to ramp up the supply voltage within a defined timeframe up
to 10 s with 1 ms step size and it can be set independently for each channel. Fur-
thermore, the channels can be sequenced to ramp up the voltage output applied
at different times. With different slew rates and delays between channel outputs, it
is easy to test multi-voltage systems reliability. For the four-channel power sup-
plies, the outputs can also be arranged into two independent subgroups.
The analog input and digital I/O interfaces at the rear panel can be activated with
an option key. The analog input allows you to control the output directly using

Welcome to R&S NGP800
R&S®NGP800
15Getting Started 5601.5603.02 ─ 12
voltage signals (0 V to 5 V analog input corresponds to 0 to Vmax or Imax) and
can be set independently for each channel. The analog inputs are galvanically
isolated from the channel outputs, making the connection simpler. The digital I/O
provides an 8-bit control port for various control functions. Each pin can be config-
ured as input or output port, to control any output channel, trigger an event, e.g.
start arbitrary or to indicate various conditions, e.g. over current protections.
The R&S NGP800 power supplies are equipped with a color 800 x 480 5" TFT
LCD touch screen and a USB and LAN interfaces to control the instrument
remotely. The R&S NGP800 power supplies can also be remote-controlled using
the GPIB option.
The user manual describes all instrument functionalities. The latest version is
