The top-class in supplying power
Their extremely high accuracy and fast load recovery times make R&S®NGU source measure units (SMU) perfect for challenging applications, such as:
  •  battery and power consumption tests
  •  supplying wireless devices with power
  •  simulation of voltage drops
 
Thanks to their extremely high accuracy and fast load recovery time, the R&S®NGU source measure units (SMU) are perfect for challenging applications. A special ammeter design is used to precisely measure current drains from nA to A in one pass – no need to make multiple measurement sweeps. The instruments’ short recovery times enable them to handle fast load changes that occur, for example, when mobile communications devices switch from sleep mode to transmit mode. With high speed data acquisition, every detail is detected down to 2 μs resolution. The R&S®NGU source measure units provide two- or fourquadrant architecture, allowing them to function both as a source and a sink to simulate batteries and loads.
 
The two-quadrant R&S®NGU201 and the four-quadrant R&S®NGU4xx provide up to 60 W of output power and sink power, respectively. The channels are floating, galvanically isolated and protected against overload and short circuits. With six measurement ranges (R&S®NGU411: five ranges) for current and a resolution of up to 6 ½ digits when measuring voltage, current and power, the R&S®NGU source measure units are perfect for characterizing devices that work from extremely low power consumption to high currents in the ampere range. Using ammeters with feedback-amplifier technology increases accuracy and widens the sensitivity down to the nA range.
 
With an acquisition rate of up to 500 000 samples per second, even extremely fast variations in voltage or current can be captured. The instruments provide fast load recovery time of < 30 μs combined with minimum overshoot even during a demanding load change. The linear design of the output stages allows the R&S®NGU source measure units to operate as a source and sink with minimum residual ripple and noise. The two-quadrant R&S®NGU201 source measure unit is a new member in the family of wireless communications test instruments, mainly designed to supply devices under test with extremely low sleep currents, such as Bluetooth® low energy devices.
