Two-quadrant operation, minimum ripple and noise
The architecture of the R&S®NGM200 power supplies allows
them to function both as a source and a sink.
The instruments automatically switch between sink and source
operation. In this example, channel 2 works as a load.
The linear design of the output stages reduces residual ripple
and noise to a minimum and makes them perfect for the
development of power amplifiers and MMICs.
Easy operation
The high-resolution capacitive touchscreen is the central
operating element for the R&S®NGM200 power supplies. Icons
clearly show the status of set protection or special functions.
When the power supply is in constant voltage mode, the
numbers and the keys light up green. Red is used for constant
current mode. The Output key lights up blue to indicate that the
channels are switched on (active).
The high-resolution display provides additional information such
as power values and statistics.
Readings with up to 6½ digit resolution
With a resolution of up to 6½ digits when measuring voltage,
current and power, the R&S®NGM200 power supplies are perfect
for measurements on devices that have low power consumption
in standby mode and high current in full load operation. Two
voltage measurement ranges and four current measurement
ranges provide a high accuracy and resolutions down to
1 µV/10 nA.
Optimized load recovery time
Battery simulation
When battery-operated devices have to be optimized for
lifecycle, the discharging behavior of the used battery type needs
to be considered. The battery simulator function makes it
possible to simulate the real battery output performance. Testing
can be based on a selected battery model, while battery
capacity, SoC and Voc can be set to any state to test the device
under specific circumstances.
The charging behavior of a battery can also be simulated, for
example when designing battery chargers. In this application,
the R&S®NGM200 is used in sink mode.
Under challenging load conditions, most power supplies
respond with slow recovery times and overshoots.
Specially developed circuits in the R&S®NGM200 power
supplies achieve a load recovery time of < 30 µs with
minimal overshoot, making them perfect for supplying
sensitive components.
