3.1 Overview
The 5000 Series Tester is a test system of power sources exercised under computer
control to test 2 and 3 lead semiconductor components. These sources, along with
conditioning loads, are connected as required to obtain the exact conditions required
for a particular test. Included are means to connect a variety of loads and to switch
sources in and out of the circuit as required. Shown in Figure 3-1 is the basic test
configuration in simplified form. DUT is the device under test.
