Abstract

A test apparatus for conducting a radiated performance test on a wireless device under controlled test conditions, the test apparatus having an anechoic chamber; a test computer; and an interface, the interface adapted to connect the test computer to the wireless device, the test apparatus being adapted to: establish a data connection on the interface between the test computer and the wireless device; initialize and start a timer for a predetermined interval on the wireless device; subject the wireless device to the radiated performance test in the anechoic chamber after the predetermined interval; and analyze test results on the test computer from a test log stored on the wireless device during the radiated performance test, wherein the interface between the test computer and the wireless device is adapted to be removed during the predetermined interval; for conducting a radiated performance test on a wireless device.

Claims (36)

1. A test apparatus for conducting a radiated performance test on a wireless device under controlled test conditions, the test apparatus comprising:

an anechoic chamber;

a test computer; and

an interface, said interface being configured to connect said test computer to the wireless device,

said test apparatus being configured to:

establish a data connection on said interface between said test computer and the wireless device;

initialize and start a timer for a predetermined interval on the wireless device;

subject the wireless device to said radiated performance test in said anechoic chamber after said predetermined interval; and

analyze test results on said test computer from a test log stored on the wireless device during said radiated performance test,

wherein said interface between the test computer and the wireless device is configured to be removed during said radiated performance test.

2. The test apparatus of claim 1 , wherein the interface is a data cable.

3. The test apparatus of claim 1 , wherein the interface is a wireless communications interface selected from a Bluetooth and an infrared interface.

4. The test apparatus of claim 1 further configured to:

reestablish said data connection between said test computer and the wireless device upon reestablishment of the interface;

retrieve the test log from the wireless device to the test computer; and

perform an analysis of said test log to provide derived test results.

5. The test apparatus of claim 1 , wherein said test computer includes a software tool for communications between the wireless device and the test computer.

6. The test apparatus of claim 5 , wherein said software tool is configured to send a command to the wireless device to establish the data connection.

7. The test apparatus of claim 5 , wherein said software tool is configured to send a command to the wireless device to start a test script.

8. The test apparatus of claim 5 , wherein the software tool is configured to send a command to the wireless device to initialize the timer.

9. The test apparatus of claim 1 , further comprising a software module configured to load a test script from the test computer to the wireless device.

10. A test apparatus for conducting a radiated performance test on a wireless device under controlled test conditions, the test apparatus comprising:

an anechoic chamber;

a test computer; and

an interface, the interface being configured to connect the test computer to the wireless device;

the test apparatus being configured to:

initialize and start a timer for a predetermined interval on the wireless device;

subject the wireless device to said radiated performance test in said anechoic chamber after said predetermined interval;

establish a data connection between the test computer and the wireless device:

retrieve a test log created during said radiated performance test and storing radiated performance test results from the wireless device to the test computer; and

perform an analysis of said test log at said test computer to provide derived test results,

wherein the interface is established between the test computer and the wireless device after the radiated performance test.

11. The test apparatus of claim 10 , wherein the interface is a data cable.

12. The test apparatus of claim 10 , wherein the interface is a wireless communications interface selected from a Bluetooth and an infrared interface.

13. The test apparatus of claim 10 , wherein said test computer includes a software tool for communications between the wireless device and the test computer.

14. The test apparatus of claim 13 , wherein said software tool is configured to send a command to the wireless device to establish the data connection.
