0009 /** The testEventiterator creates Event objects with known properties
0010    from scratch. The events contain 1 frame and 3 packets. The first 2
0011    packets with id's 1001 and 1002 look like ADC's whose channel i
0012    contains the value i, which can be used to verify that a certain
0013    channel actually ends up where it should. The third packet 1003
0014    has four channels which give values according to gaussian distributions
0015    with RMS 10,100,1000, and 10000, respectively.
