Abstract
According to some embodiments, a method includes placing a device under test (DUT) in a test chamber and applying a pulse-modulated RF wireless test signal to the DUT in the test chamber. The method further includes detecting an acoustic output of the DUT. In addition or as an alternative to applying the pulse-modulated test signal, the test signal strength may be at a level of 30 V/m or 90 V/m. If the DUT is a telephone, it may be coupled via a voice signal path to another telephone, and an output of the other telephone may also be detected.
Claims18
A method comprising:
- placing a device under test (DUT) in a test chamber;
- wirelessly applying a pulse-modulated radio frequency (RF) test signal to the DUT in the test chamber using an antenna;
- and
- detecting a power level of an acoustic output of the DUT with a receiving device, wherein the acoustic output is in a range of 20 Hz to 20 kHz.
A method comprising:
- placing a device under test (DUT) in a test chamber;
- wirelessly applying a radio frequency (RF) test signal to the DUT in the test chamber using a mobile wireless telephone;
- and
- detecting a power level of an acoustic output of the DUT in a range of 20 Hz to 20 kHz using a receiving device and a bandpass filter;
- wherein the test signal has a strength of at least 30 V/m in at least a portion of the test chamber.
An apparatus comprising:
- a test chamber;
- an antenna in the test chamber;
- test signal means, coupled to the antenna, for applying a wireless pulse-modulated RF test signal to a device under test located in the test chamber using the antenna;
- and
- means, associated with the test chamber, for detecting and measuring an acoustic output level of the device under test, wherein the acoustic output is in a range of 20 Hz to 20 kHz.
