The following pages show the measured results for the two configurations that
were tested. The measurement of background emissions that were present in
the screened room was performed with the test PCB installed in the TEM cell,
but at this point no power was applied to the board.
Measurements were then taken in the North and South orientations with the
power applied to the test PCB and the test software being executed in flash
memory.
