Abstract
A method of measuring a total radiated power of a device under test by a test system with a base station simulator, a measurement antenna assigned to the base station simulator and a control and/or measurement equipment is described. The method includes: establishing a radio resource control connection between the device under test and the base station simulator via the measurement antenna; activating an uplink-beam lock function at the device under test; and performing a total radiated power measurement by the control and/or measurement equipment while continuously sending a downlink signal from the base station simulator via the measurement antenna to the device under test. A test system is further described.
Claims18
A method of measuring a total radiated power of a device under test by a test system having a base station simulator, a measurement antenna assigned to the base station simulator and a control and/or measurement equipment, wherein the method comprises:
- establishing a radio resource control connection between the device under test and the base station simulator via the measurement antenna;
- activating an uplink-beam lock function at the device under test;
- and
- performing a total radiated power measurement by the control and/or measurement equipment while continuously sending a downlink signal from the base station simulator via the measurement antenna to the device under test,
- wherein the downlink signal continuously sent comprises an acknowledgement signal.
A test system for measuring a total radiated power of a device under test, comprising:
- a device under test;
- a base station simulator;
- a measurement antenna assigned to the base station simulator;
- and
- a control and/or measurement equipment,
- wherein a radio resource control connection is established between the device under test and the base station simulator via the measurement antenna, wherein an uplink-beam lock function is activated at the device under test, and wherein the test system is configured to perform a total radiated power measurement of the device under test while continuously sending a downlink signal from the base station simulator via the measurement antenna to the device under test, wherein the downlink signal continuously sent comprises an acknowledgement signal.
