Abstract: An apparatus and method for enhancing a one-wire bus wherein a translator is inserted between a master and one or more slave devices. The translator monitors the data stream between the master and the slave device and, upon a reaching a predetermined position in the data stream, inserts known data into the data stream. The translator includes: a primary one-wire bus for communicating with the master; and at least one secondary one-wire buses each of which can communicate with one or more slave devices.

Abstract: A test system having a shielded enclosure and common air interface for testing the transmit and receive functionality of wireless communication devices such as mobile phones. A test system according to the present invention provides improved fault coverage by permitting robust testing of the entire signal path of a wireless device, including the antenna structure. In one embodiment of the invention, an RF-shielded enclosure having a test chamber is provided. The structure of the shielded enclosure blocks ambient RF energy from entering the test chamber and interfering with testing operations. The shielded enclosure may be lined with an RF absorbing material to improve test repeatability. A novel test antenna structure is disposed in the test chamber for wirelessly communicating test signals to a device under test.
