Optimized load recovery time
Power supplies usually respond to abrupt load changes with overshoot and slow recovery times.
Thanks to specially optimized control circuits, the R&S®NGM200 series achieves recovery times of < 30 µs.

Rohde & Schwarz R&S®NGM200 Power Supply Series 5
The R&S®NGM200 power supplies have a circuit design
that allows the user to determine how the power supply
regulates load changes. The “Fast” default setting is
optimized for speed, achieving recovery times of <30µs.
Deactivating “Fast” slightly increases the recovery time,
focusing on preventing overshoots under special load
conditions.
The R&S®NGM200 power supplies regulate the internal
impedance very fast. Especially in the range from
–50mΩ to 2Ω, recovery times of <200µs can be
achieved.
Minimum residual ripple and low noise
Advanced electronic circuitry is often very complex and
sensitive to interference on the supply lines. In order to
supply interference-free voltage to such sensitive DUTs,
the power supplies must provide extremely stable output
voltages and currents. All types of ripple and noise need
to be avoided. The R&S®NGM200 power supplies have
linear regulation and are ideal for sensitive DUTs.
Technology for
challenging tasks
Fast load regulation
Consumer electronics such as mobile phones and IoT
devices require very little power in sleep mode. However,
the current increases abruptly as soon as the device
switches to transmit mode. A power supply used to power
such DUTs must be capable of handling load changes
from a few µA to the ampere range without creating
voltage drops or overshoots.
The measured currents and voltages are displayed with 6 ½ digit
resolution. The power supply automatically switches from source to
sink mode. In the example, channel 2 is operating as a load. This is
indicated by a negative current reading.
