Abstract: A test system for testing a device under test is described. The test system includes a testing circuit and the device under test. The testing circuit is configured to establish a wireless connection with the device under test based on a wireless communication standard having a low energy protocol. The wireless connection includes a plurality of channels, wherein the plurality of channels is configured to transmit data packages between the testing circuit and the device under test. The testing circuit and the device under test are configured to communicate with each other via the plurality of channels by a channel hopping technique. A radio frequency (RF) level of a signal transmitted by the testing circuit in at least one test channel to be tested, which belongs to the plurality of channels, is lower than an RF level of a signal transmitted by the testing circuit in at least one other channel of the plurality of channels. Further, a test method of testing a device under test is described.

Abstract: The invention provides an analysis of a Bluetooth Low Energy implementation by measuring a packet error rate (PER) on a communication channel between the BLE implementation and a test device.

Abstract: A measuring device for providing an angle of departure determining test signal to a device under test, is provided. The measuring device comprises a signal generator and a single output port. The signal generator is adapted to generate the angle of departure determining test signal, emulating an antenna array angle of departure determining signal, comprised of a plurality of individual array antenna signals, thereby emulating an angle of departure of the angle of departure determining test signal. The single output port is adapted to output the angle of departure determining test signal to the device under test.

Abstract: Methods and apparatus for improving the result of online promotion testing are disclosed. In one or more embodiments, base-lining is employed to improve the mapping between the online test promotion responses and projected in-store result. Alternatively or additionally, the test population responses may be adjusted to account for differences between the test population and the in store customer population.

Abstract: Device and method for testing wireless devices without a physical connection to the wireless device which has to be tested. Accordingly, the reception and transmission of the wireless device which has to be tested is controlled only by a test data sequence which is repeatedly sent from a test device to the wireless device which has to be tested. Accordingly, a measurement of the responses from the device which is to be tested can be performed in order to evaluate the operation of the respective device.

Abstract: A method of testing a Bluetooth low energy device over-the-air is described, wherein a Bluetooth low energy connection is established. An enable test mode command is transmitted to the device under test. The testing is started with transmitting at least one of a test transmission command and a test receiving command. Test radio frequency test physical layer packets are transmitted in a channel to be tested. A channel switching sequence takes place. At least one of a stop transmission command and a stop receiving command is transmitted once the intended testing on the channel to be tested has been completed. Further, a testing system is described.
