Rohde & Schwarz R&S®NGE100B Power Supply Series 5
Color-coding of operating conditions
All operating conditions are shown clearly on the 3.5"
QVGA display (320 × 240 pixel), including the output pow-
er and the status of any protective functions. Colors indi-
cate the different operating conditions:
❙ Active outputs are shown in green when working in
constant voltage mode and in red when working in
constant current mode
❙ Inactive outputs are displayed in white. Whenever a
channel is in the setting mode, the number to be set is
marked by a blue background
Comfort features for special applications
Some applications require that the user vary the voltage or
the current during a test sequence, for example to simu-
late different charging conditions of a battery. Here, the
EasyArb function is a convenient solution that is not usual-
ly found in basic class power supplies. EasyArb allows the
user to program time/voltage or time/current sequences,
either manually via the user interface, or via the external
interfaces.
Sometimes test sequences have to simulate operating
conditions where the abrupt rise of the supply voltage
has to be avoided. The EasyRamp function of the
R&S®NGE100B power supply series offers the solution.
The output voltage can be increased continuously within
a 10ms to 10s timeframe. Of course the EasyArb and
EasyRamp functions can both be controlled manually or
remotely.
Tracking and link functions
The separate output channels can function as individual
power supplies, but demonstrate their versatility when
combined. Running in parallel, higher currents can be
achieved; serial connected channels yield higher voltages.
The tracking function allows the user to vary the voltage
on all channels in parallel for very convenient operation.
The link function of the electronic fuse makes the instru-
ment even more versatile. Users can set up the power
supply so that all channels are switched off if one channel
hits its limit. Or it can be set up to leave one channel work-
ing, for example to keep the fan powered to cool down the
DUT. The status of fuses and all other protection functions
is always shown on the display.
Five memory keys to save/recall instrument
settings
Frequently used instrument settings can easily be stored/
recalled via five memory keys on the front panel.
Easy operation
Straightforward operation
All basic R&S®NGE100B power supply functions can be
operated via direct keys on the front panel – no need to
maneuver through a jungle of menus. Just press the "Volt-
age" key, select an output channel and use the rotary knob
or the arrow keys to adjust the desired voltage in steps
down to 10mV. A constant output current can be similarly
set in steps down to 1mA.
If channels need to be operated simultaneously, for ex-
ample to increase the voltage of a device from ±12V to
±15V, press the "Track" key, select the two channels for
positive and negative voltage and adjust the two voltages.
The rotary knob will adjust the two voltages symmetrically.
Activating or deactivating the electronic fuses is just as
easy – by simply pressing one key on the front panel.
The different operating conditions are marked by colors: con-
stant voltage operation is indicated in green, constant current op-
eration in red, inactive channels are shown in white, a number
marked by a blue background indicates that the channel is in set-
ting mode
Executed protection functions are always displayed on the screen
