    Abstract: Method for testing a radio frequency (RF) data packet signal transceiver device under test (DUT) including communicating via each one of multiple available signal channels. Data packets exchanged between a tester and DUT as a normal part of a communication link initiation sequence are exchanged in such a manner that the tester transmits via all available channels simultaneously, thereby ensuring that a properly working DUT will always transmit in response. For example, in the case of a Bluetooth low energy transceiver, advertisement, scan request and scan response data packets can be used in such manner.
