Non-synchronized radio-frequency testing
First Claim
1. A method of testing a device under test with a test station, the method comprising:
- loading at least one of the device under test and the test station with information identifying an order in which to use each of a plurality of network access technologies to test the device under test with the test station; and
using the test station, performing tests on the device under test by conveying radio-frequency test signals of a first type between the device under test and the test station based on the information for a first time period and subsequently conveying radio-frequency test signals of a second type that is different than the first type between the device under test and the test station based on the information for a second time period immediately following the first time period without synchronizing the device under test to the test station.

Abstract
A device under test (DUT) may be tested using a test station having a test host, a non-signaling tester, and a test cell. During testing, the DUT may be placed within the test cell, and the DUT may be coupled to the test host and the tester. In one suitable arrangement, the DUT may be loaded with a predetermined test sequence. The predetermined test sequence may configure the DUT to transmit test signals using different network access technologies without synchronizing with the tester. The tester may receive corresponding test signals and perform desired radio-frequency measurements. In another suitable arrangement, the tester may be loaded with the predetermined test sequence. The predetermined test sequence may configure the tester to generate test signals using different network access technologies without establishing a protocol-compliant data link with the DUT. The DUT may receive corresponding test signals and compute receive signal quality.

15. A method of testing a device under test with a test station, the method comprising:
-
loading at least one of the device under test and the test station with information identifying an order in which to use each of a plurality of network access technologies to test the device under test with the test station; and using the test station, performing tests on the device under test by conveying radio-frequency test signals between the device under test and the test station based on the information without synchronizing the device under test to the test station, wherein performing the tests on the device under test comprises performing the tests on the device under test while the device under test is placed in a transverse electromagnetic cell that isolates the device under test from external interference, wherein the test station further comprises a test unit coupled to the device under test via a radio-frequency cable. - View Dependent Claims (16, 17, 18)
