Claim 20:
21. A test system comprising:
test sites comprising test sockets for testing devices under test (DUTs);
pickers for picking DUTs from the test sockets or placing the DUTs into the test sockets, each picker comprising a picker head for holding a DUT;
a gantry on which the pickers are mounted, the gantry being configured to move the pickers relative to the test sites to position the pickers for picking the DUTs from the test sockets or placing the DUTs into the test sockets; and
packs comprising the test sockets and at least some test electronics for performing tests on the DUTs in the test sockets, where different packs are configurable to have different configurations, the different configurations comprising at least different numbers of test sockets arranged at different pitches;
wherein the test sockets are arranged in at least one array that is accessible to the pickers on the gantry;
wherein the gantry comprises a beam that spans across the at least one array of test sockets and that is configured to move over the at least one array of test sockets in a direction perpendicular to the beam; and
wherein the pickers are arranged linearly along the beam and are configured to move linearly along the beam;
wherein the pickers are controllable to move linearly along the beam to change a pitch of the pickers along the beam;
wherein the pickers are controllable to move linearly along the beam to change the pitch while the beam moves over the at least one array of test sockets in the direction perpendicular to the beam; and
wherein the pickers are controllable to move linearly along the beam to change the pitch to match pitches of different sets of test sockets in different packs installed in the test system.
