Voltage and current generator

Abstract

A voltage and current generator (1) includes an operation interface (11) that receives an operation from a user, an output stage (16) that outputs an electrical signal to a load (30), detectors (17, 18) that detect a measured value of the electrical signal outputted by the output stage (16), and a control calculator (15) that controls operation of the output stage (16), based on the deviation between a target value of the electrical signal as set by the user via the operation interface (11) and the measured value of the electrical signal as detected by the detector, so that the measured value of the electrical signal approaches the target value. The control calculator (15) performs control, including a compensation operation to cancel a low-pass filter effect in output resistance of the output stage (16) and the load (30), based on an impedance of the load (30) as set by the user via the operation interface (11).
