5.9. Minimum Antenna Separation Test
Summary Description: This test determines the effect on FER of subjecting the Motorola UWB
receiver to a very strong input signal. Perform this test by moving the source transceiver
antenna close to the destination transceiver antenna until a desired FER level is achieved. Then
measure the physical separation of these two antennas.
During this test the source transceiver operates in framed mode. In other words, numerous
UWB frames, each with a header and payload, are sent.
