2 Welcome to R&S NGA100
The one-channel or two-channel power supply series are based on a classical trans-
former concept with high efficiency electronic pre-regulators and secondary linear reg-
ulators. This concept allows the instrument to achieve the high output power within a
minimum space, high efficiency and lowest residual ripple.
The R&S NGA100 power supply series feature galvanically isolated, floating overload
and short-circuit proof outputs with adjustable power ratings. The outputs can be con-
nected in series or in parallel, thus making high currents and voltages available.
Multi-purpose protection functions are available for each channel which you can set
separately, such as overcurrent protection (FUSE), overvoltage protection (OVP), over-
power protection (OPP) and overtemperature protection (OTP). If such a limit is
reached, the affected output channel is automatically turned off and an indicator mes-
sage (FUSE, OVP, OPP or OTP) is displayed. The overcurrent protection can be linked
to other channel (FuseLink function). In this case, all linked channels are turned off
when the set channel reaches its limit.
The EasyArb function allows channel 1 (Ch 1) to have freely definable voltage and cur-
rent 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 condi-
tions of a battery. With EasyRamp function, the R&S NGA100 provides the operating
condition to simulate the continuous rise of the supply voltage within a defined time-
frame of 10 ms to 10 s.
Four data lines of the digital I/O interface are mutually independent and can be used as
trigger input or trigger output separately. Various trigger conditions (e.g. fuse tripped,
voltage, current, indicator messages) can be used to turn off, on or invert the output
state when the trigger condition is met.
All R&S NGA100 power supply series are equipped with a color LCD display (320 x
240 pixels resolution). The R&S NGA100 comes with a USB interface, LAN and
optional wireless LAN (WLAN) interface.
For models with WLAN, network connection can also be established wirelessly.
This user manual contains a description of the functionalities that the instrument pro-
vides. The latest version is available for download at the product homepage (http://

3.2 Ambient Conditions
The allowed operating temperature ranges from +5 °C to +40 °C (pollution category 2).
The maximum relative humidity (without condensation) is at 80 %.
During storage and transport, the temperature must be between -20 °C and +70 °C. In
case of condensation during transportation or storage, the instrument requires approxi-
mately two hours to dry and reach the appropriate temperature prior to operation. The
instrument is designed for use in a clean and dry indoor environment. Do not operate
with high dust and humidity levels, if danger of explosion exists or with aggressive
chemical agents.
Any operating position may be used; however adequate air circulation must be main-
tained. For continuous operation, a horizontal or inclined position (integrated stand) is
preferable.
Specifications with tolerance data apply after a warm-up period of at least 30 minutes
at a temperature of 23 °C (tolerance -3 °C / + 7 °C).
The heat produced inside the instrument is guided to the exterior via temperature-con-
trolled fan. Each channel has multiple temperature sensors which check the heat gen-
eration in the instrument and control the fan speed.
It is necessary to ensure that there is sufficient space around the instrument sides for
heat exchange. If the temperature inside the instrument increases more than the

3.3 Measurement Categories
This instrument is designed for supplying power-on circuits that are only indirectly con-
nected to the low voltage mains or not connected at all. The instrument is not intended
for measurements within the measurement categories II, III or IV; the maximum poten-
tial against earth generated by the user must not exceed 250 V peak in this application.
The following information refers solely to user safety. Other aspects, such as the maxi-
mum voltage, are described in the technical data and must also be observed.
The measurement categories refer to transients that are superimposed on the mains
voltage. Transients are short, very fast (steep) current and voltage variations which
may occur periodically and non-periodically. The level of potential transients increases
as the distance to the source of the low voltage installation decreases.
●Measurement CAT IV: Measurements at the source of the low voltage installations
(e.g. meters)
●Measurement CAT III: Measurements in building installations (e.g. power distribu-
tion installations, power switches, firmly installed sockets, firmly installed engines
etc.)
●Measurement CAT II: Measurements on circuits electronically directly connected to
the mains (e.g. household appliances, power tools, etc.)
●0 (instruments without measured measurement category): Other circuits that are
not connected directly to the mains
3.4 Mains Voltage
The instrument uses 50 Hz / 60 Hz mains voltages ranging from 100 VAC, 115 VAC or
230 VAC (tolerance ± 10 %). Mains voltage must be set correctly by moving the selec-
tor according to the voltage selector located at the bottom panel. The input line fuse is
accessible externally. Power socket and fuse holder form a single unit.
You need to first disconnect the power cord from the connector before you can safely
replace the fuse (as long as the fuse holder is undamaged). Next, the fuse holder must
be pried out using a screwdriver. The starting point is a slot next to the contacts. The
fuse can then be forced out of its mounting and must be replaced with an identical fuse
(see information about the fuse type on the rear panel). The fuse holder is inserted
against the spring pressure until it locks into place. The use of mended fuses or short
