摘要： A test system for characterizing an antenna tuning element is provided. The test system may include a test host, a radio-frequency tester, and a test fixture. The test system may calibrate the radio-frequency tester using known coaxial standards. The test system may then calibrate transmission line effects associated with the test fixture using a THRU-REFLECT-LINE calibration algorithm. The antenna tuning element may be mounted on a test socket that is part of the test fixture. While the antenna tuning element is mounted on the test socket, scattering parameter measurements may be obtained using the radio-frequency tester. An equivalent circuit model for the test socket can be obtained based on the measured scattering parameters and known characteristics of the antenna tuning element. Once the test socket has been characterized, an equivalent circuit model for the antenna tuning element can be obtained by extracting suitable modeling parameters from the measured scattering parameters.

摘要： A test system for testing a device under test (DUT) is provided. The test system may include a DUT receiving structure configured to receive the DUT during testing and a DUT retention structure that is configured to press the DUT against the DUT receiving structure so that DUT cannot inadvertently shift around during testing. The DUT retention structure may include a pressure sensor operable to detect an amount of pressure that is applied to the DUT. The DUT retention structure may be raised and lowered vertically using a manually-controlled or a computer-controlled positioner. The positioner may be adjusted using a coarse tuning knob and a fine tuning knob. The positioner may be calibrated such that the DUT retention structure applies a sufficient amount of pressure on the DUT during production testing.

摘要： A test system for testing an antenna tuning element is provided. The test system may include a tester, a test fixture, and a probing structure. The probing structure may include probe tips configured to mate with corresponding solder bumps formed on a device under test (DUT) containing an antenna tuning element. The DUT may be tested in a shunt or series configuration. The tester may be electrically coupled to the test probe via first and second connectors on the test fixture. An adjustable load circuit that is coupled to the second connector may be configured in a selected state so that a desired amount of electrical stress may be presented to the DUT during testing. The tester may be used to obtain measurement results on the DUT. Systematic effects associated with the test structures may be de-embedded from the measured results to obtain calibrated results.

摘要： A method to generate name records by a service gateway includes: receiving a name service request including a name from a host; creating a name service request using the name; sending the name service request to a name service server; receiving a response from the name service server, the response including a service server name record with one or more service server name entries corresponding to the name; generating and storing service gateway name records using the name and the name entries; and sending a selected service gateway name record to the host as a response to the name service request. When a subsequent name service request including the name is received, the service gateway compares the name against the stored service gateway name records, and in response to finding a match, sending the given service gateway name record as a response to the subsequent name service request.

摘要： A service gateway includes a fast path module for processing data packets without using packet buffers and a normal path module for processing data packets using packet buffers. The fast path module receives a service request data packet from a client side session, determines that the service request data packet cannot be processed by the fast path module, and in response, sends the service request data packet to the normal path module. After receiving the service request data packet, the normal path module retrieves a first proxy session record created by the fast path module, where the first proxy session record is associated with a client session record for the client side session, creates a second proxy session record based on the service request data packet and the client session record, and processes the service request data packet according to the second proxy session record.
