Utility
High performance current source power supply
12 Oct 20
A system can include a device under test (DUT) having a DUT voltage, a cable connected to the DUT, the cable having a cable inductance, and a power supply configured as a current source to provide a wide bandwidth voltage source to the DUT, wherein the DUT voltage is independent of the cable inductance.
