These modules are leveraged from an earlier product, the HP/Agilent 8920A, which is primarily an analog communications test set. Many of the audio circuits in these assemblies are not used by the HP/Agilent 8922 and will not be covered in this discussion. Refer to the HP/Agilent 8920A Assembly Level Repair manual if further detail on these modules is required.

For the HP/Agilent 8922, the function of the A6 Signaling Source/Analyzer is simply to create sinusoidal audio signals. The analyzer capabilities of this module are not used in the HP/Agilent 8922. The A4 Modulation Distribution assembly provides gain, attenuation, and distribution functions of these audio signals as well as the AM/Speech input from the front panel. The interconnection of these modules is shown on Block Diagram 2.

The diagnostic procedures for these modules are extensive. Like the hardware, the diagnostics have been leveraged from the HP/Agilent 8920A and test more of the circuits than are actually used in the HP/Agilent 8922. The diagnostic output from these modules documents the exact circuits in the modules which are tested.
