R&S® NGU401 Source-Measure-Unit (SMU)

Description

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

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 short recovery times enable the instruments to handle fast load changes when mobile communications devices switch from sleep mode to transmit mode. Every detail is detected down to 2 μs resolution with high speed data acquisition. R&S®NGU source measure units have two- or four-quadrant architecture to function both as a source and a sink.

Both the two-quadrant devices and the four-quadrant devices deliver up to 60 W output power, or can do so Record them.

Due to the linear design of the output stages, this series enables source and sink operation with minimal ripple and noise.

Special features

Diverse output parameters

Various parameters can be set at the outputs of the R&S®NGU source measure units, for example the output impedance, a delay to switch on the outputs and different trigger modes.

Battery simulation (NGU201)

Battery simulation: the main parameters to characterize a battery’s condition are summarized in one display. The battery simulation option includes data sets of common battery types that can be easily modified.

Graphic representation

The high-resolution display can also be used for graphical presentations; in this example the charging current of a capacitor is displayed while the voltage is increased stepwise.
