2.2 Standard Test
The standard test is defined by sending a number of packets over one or more channels. The bit
errors are counted and compared against an error threshold number and the pass/fail result is
displayed. See
Appendix - A on page 19 for instructions on changing the standard test configuration.
After the test environment is set up, put the device to be tested into manufacturing test mode and
place it in the shielded container. The DUT should respond to the standard test executed by the test
fixture. Note that the foam in some shielded test boxes is conductive. The bare DUT board (if testing
a bare PCB) should be placed in a fixture, not directly on the foam of the box. This also helps ensure
that the DUT to antenna alignment is the same from test to test, which can make a large difference in
signal strength at the DUT. See
Figure 2-3 .
