Testing systems with automated loading equipment and positioners

摘要

A test system may be provided in which devices under test are tested using radio-frequency test stations. A test station may include a test host, a test unit coupled to the test host, and a shielded enclosure. The shielded enclosure may contain a test antenna coupled to the test unit via a radio-frequency cable. A computer-controlled loading arm may be used to place a device under test on a positioner within the test enclosure. The test enclosure may have an enclosure door that is opened and closed using a computer-controlled pneumatic cylinder. When the enclosure door is closed, a portion of the enclosure door may actuate one or more levers on the positioner, which may in turn actuate one or more positioning arms to press the device under test against one or more guide surfaces on the positioner, thereby precisely positioning the device under test within the test enclosure.

主权项

1. Test apparatus for testing a device under test, comprising:
a test enclosure having an enclosure door; and a positioner in the test enclosure that is configured to receive the device under test, wherein the positioner includes at least one positioning arm, an actuating member that controls the positioning arm, and at least two guide surfaces against which the device under test is pressed, the positioner being configured to automatically position the device under test as a result of closing the enclosure door.
