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 four-quadrant architecture, allowing them to function both as a source and a sink.
