Rohde & Schwarz R&S®NGM200 Power Supply Series 11
Numerical values can be entered using the virtual touchscreen keyboard
or the rotary knob.
The large high-resolution display makes it easy to read the voltage and
current values (even at great distances) and provides a lot of additional
information.
Arb sequences can be programmed to run much faster
with the R&S®NGM200 than with other power supplies.
The dwell time for a single voltage or current value can be
set with a resolution of up to 1ms. This makes it possible
to program very short drops in voltage to test the power-
up behavior of a DUT. The dwell times can also be set in
the range of hours to implement test sequences extending
over days or weeks for long-term testing.
EasyRamp function
Sometimes test sequences have to simulate operat-
ing conditions where the abrupt rise of the supply volt-
age has to be avoided. The EasyRamp function of the
R&S®NGM200 power supplies provides the solution. The
output voltage can be increased continuously within a
time frame of 10ms to 10s. The EasyRamp function can
be operated both manually and remotely.
Save and recall instrument settings
The save and recall functions make it easy to save and
recall frequently used settings.
Color coding of operating modes
Colors are used to indicate the different modes. For
example, active channels in constant voltage mode light
up green, while red is used for constant current mode.
When the power supply is in constant resistance mode,
the numbers are displayed in cyan.
Each of the R&S®NGM202 channels can be selected indi-
vidually using the channel keys. The Output key is used to
switch the selected channels on or off. The key lights up
blue when it is switched on.
QuickArb function
Some applications require the voltage or the current to
be varied during a test sequence, for example when simu-
lating different charging conditions of a battery. The Arb
function allows users to manually configure time/voltage
or time/current sequences via the user interface or to pro-
gram them via external interfaces.
Other power supplies also offer an Arb function, but the
QuickArb function of the R&S®NGM200 power supplies
sets new standards. More points (4096points) are sup-
ported per cycle. It is also possible to interpolate between
the discrete points and select whether the sequence of
voltage values 1V – 2V – 3V is to be run as steps, or
whether the voltage values are to be increased using linear
interpolation.
