Four-terminal device connections
To test a four-terminal device, two PMUs are usually required. The following figure shows the four
PMU channels connected to a four-terminal MOSFET. This configuration enables you to have
complete flexibility to enable pulsing and measuring at any terminal on the device. Notice that the
shields of the SMA cables from all four channels are connected as closely as possible to the device
under test.
