Four-terminal device connections
To test a four-terminal device, two PMUs are usually required. The next 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.
