You can also connect a two-terminal device to the two channels of a PMU, as shown in the following
figure. In this case, channel 1 will source/pulse voltage, and channel 2 will measure the resulting
current. Make sure you connect the shields of the SMA cables close to the device under test. This
method avoids problems of capacitive charging (see PMU capacitive charging/discharging effects (on
page 3-35)).
