摘要： The present invention provides a method for generating random jitter test patterns by generating a sequence of maximum-size asynchronous packets according to the P1394b standard and transmitting the sequence to the device under test. The present invention provides a method for generating jitter test patterns by disabling the transmitter data scrambler of the second device; clearing the port_error register of the device under test; and sending a test pattern to said device under test. The present invention provides for a method for generating supply noise test patterns comprising: transmitting a test pattern to the DUT comprising a maximum length asynchronous packet containing alternate 0016 and FF16 bytes.

摘要： The present invention provides a computer readable medium containing instructions for generating random jitter test patterns by generating a sequence of maximum-size asynchronous packets according to the P1394b standard and transmitting the sequence to the device under test. The instructions are executed to generate jitter test patterns by disabling the transmitter data scrambler of the second device; clear the port_error register of the device under test; and send a test pattern to said device under test.
