A faulty attenuator (A14 or A15) will cause this to fail. A second possible cause can be
the A13 Front End Driver not properly driving an attenuator.
NOTE: This test might fail due to incorrect calibration data of the 8494 and 8496 step
attenuators. Make sure you have entered the calibration data for the step attenuators that
you're using. Please refer to the
Enter Equipment Calibration Data section in the TME
help for details on how to enter this data. You must enter the data for the following
columns to obtain valid results: Attn(dB), Uncert(dB) and ReflSize.
