If this test fails at input power levels greater than -15 dBm, suspect the A8 Analog IF
Assembly (gain compression), or possibly the A7 Digital IF Assembly. Failures at input
power levels of less than -15 dBm may be caused by the A7 Digital IF Assembly (ADC).
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.
