Technical Discussion

Block Diagram Theory of Operation

The HP/Agilent 8922 can be divided into two instruments, a signal generator and a signal analyzer. This discussion is intended to follow the block diagrams in chapter 13. The assemblies in Block Diagrams 1 and 2 are covered ﬁrst. These are the primary assemblies where it is possible to do assembly level measurement and troubleshooting. All the hardware in Block Diagrams 1 and 2 are common to all HP/Agilent 8922 instruments. Block Diagrams 3 and 4 illustrate hardware that is unique to the HP/Agilent 8922B and HP/Agilent 8922E/F/G/H respectively. Because these modules are primarily digital, the discussion on this hardware is limited to a high level functional description. Often troubleshooting these boards is difﬁcult at the module level without sophisticated logic or signature analysis. Module swap is the fastest way to troubleshoot hardware problems for these assemblies. The ﬁnal discussion focuses on the modules in Block Diagram 5. More information about troubleshooting display and controller problems is also included in chapter 5.

When important, the input and output speciﬁcations for most assemblies are tabulated in chapter 12, Module I/O Specs. For additional details on the exact signal levels and frequencies for assembly inputs and outputs, refer to chapter 12, Module I/O Specs.
