Abstract
A test system comprises a device under test and a testing device. The device under test comprises a first microphone, wherein the first microphone is configured to receive sound waves. The testing device comprises a first speaker, wherein the first speaker is configured to generate sound waves. The testing device is configured to generate a first acoustic command signal via the first speaker, wherein the first acoustic command comprises a first test command. The device under test is configured to receive the first acoustic command signal via the first microphone. The device under test is configured to generate a first electromagnetic test signal based on the first test command.
Claims16
A test system comprising:
- a device under test and a testing device,
- said device under test comprising a first microphone, wherein said first microphone is configured to receive sound waves,
- said testing device comprising a first speaker, wherein said first speaker is configured to generate sound waves,
- said testing device being configured to generate a first acoustic command signal via said first speaker, said first acoustic command comprising a first test command,
- said device under test being configured to receive said first acoustic command signal via said first microphone, and
- said device under test being configured to generate a first electromagnetic test signal based on said first test command,
- wherein said testing device comprises a housing, wherein the housing defines an electromagnetically shielded space, and wherein said device under test is placed in the electromagnetically shielded space,
- wherein said first speaker is located in the electromagnetically shielded space, and
- wherein the housing comprises an electromagnetically shielded connector extending from the electromagnetically shielded space to an exterior of the housing, wherein said shielded connector is connected to said first speaker.
A test system comprising a device under test and a testing device,
- said device under test comprising a first speaker, wherein said first speaker is configured to generate sound waves,
- said testing device comprising a first microphone, wherein said first microphone is configured to receive sound waves,
- said device under test being configured to generate a first acoustic command signal via said first speaker, said first acoustic command signal comprising a first test command,
- said testing device being configured to receive said first acoustic command signal via said first microphone,
- and said testing device being configured to generate a first electromagnetic test signal based on said first test command,
- wherein said testing device comprises a housing, wherein the housing defines an electromagnetically shielded space, and wherein said device under test is placed in the electromagnetically shielded space,
- wherein said first microphone is located in the electromagnetically shielded space, and
- wherein the housing comprises a shielded connector extending from the electromagnetically shielded space to an exterior of the housing, wherein said shielded connector is connected to said first microphone.
A test method for testing a device under test via a testing device, comprising:
- generating a first acoustic command signal via a first speaker of said testing device, said first acoustic command signal comprising a first test command;
- receiving said first acoustic command signal via a first microphone of said device under test;
- and
- generating a first electromagnetic test signal based on the first test command,
- wherein the device under test is placed in an electromagnetically shielded space defined by a housing of the testing device,
- wherein said first speaker is located in the electromagnetically shielded space, and
- wherein the housing comprises a shielded connector extending from the electromagnetically shielded space to an exterior of the housing, wherein said shielded connector is connected to said first speaker.
