SWEEP TOOL FOR R&S® NGU201, NGU401 AND NGM200

Source measure units R&S®NGU401 and R&S®NGU201 are capable of precise current measurements from sub-microampere up to ampere. This application note provides a tool which generates a voltage or current sweep using the arbitrary function of the instruments. A fast log captures voltage and current values during the sweep. Subsequently the application program determines the voltage and current value for each sweep step and plots the results in an I-V curve .

The tool can be utilized to characterize all kinds of two-pole devices like diodes, LEDs and solar panels.

This application note can also be used in connection with DC power supplies R&S®NGM201 and R&S®NGM202.
