Audio Analyzer 1 Internal Paths

This test checks the A3 Audio Analyzer 1 assembly. Using the AFG1 output of the A6 Signaling Source/Analyzer assembly (through the A4 Modulation Distribution assembly), the 12 internal paths of the A3 Audio Analyzer 1 are checked. Two of the paths are not used in the HP/Agilent 8922 and will be shown as “No optional high(low)-pass filter sensed”. (Ignore this error message on this test.) Paths 1 through 4 are routed directly to the voltmeter through the AUD1_VM output, while paths 5 through 12 are routed to the peak detector in the A2 Audio Analyzer 2 assembly before being routed to the voltmeter through the AUD2_VM output. The gain and coupling are varied and each path is checked.

Audio Analyzer 1 External Paths

This test checks the A3 Audio Analyzer 1 assembly. The front panel AUDIO IN path is selected and de-selected while using an external connection from the front panel AUDIO OUT connector (which uses the AFG1 output from the A6 Signaling Source/Analyzer routed through the A4 Modulation Distribution assembly). The signal is routed to the voltmeter through the AUD1_VM output.

Audio Analyzer 2

This test checks the A2 Audio Analyzer 2 assembly. Using the AFG1 output from the A6 Signaling Source/Analyzer assembly routed through the A4 Modulation Distribution assembly to the MOD_MON output, the 14 paths through the A2 Audio Analyzer 2 are checked. Each of the measurements go directly to the voltmeter through the AUD2_VM output.
