FDP_APC_EXT.1 Test 2-AO requires detection of frequencies which are subject to attenuation as per FDP_AFL_EXT.1. It is possible that some of these frequencies may not be detectable as required in Step 5. Frequencies above 20 kHz (and outside the range of human hearing) may not be detected, as long as the lab ensures that the testing equipment can detect these frequencies under normal conditions.

FDP_APC_EXT.1 Test 2-AO in Supporting Document for AO PP-Module v1.0 is modified as follows (additions underlined):

Step 5: Use the tone generator program on the first computer to generate a sine wave audio tone for each of the designated frequencies. Verify that the audio is present in the audio spectrum analyzer software on the computer connected to the TOE analog audio output device interface and is not present in the audio spectrum analyzer software on any of the non-selected computers. This step does not fail if frequencies above 20 kHz are not present in the software on the connected computer due to attenuation as per FDP_AFL_EXT.1.
