Assembly-Level Troubleshooting with Block Diagrams
Using the Procedures in this Chapter
Using the Procedures in this Chapter
This chapter contains a troubleshooting procedure for each of the following assemblies in your signal
generator:
• A9 Output Board
• A11 Reference Board
• A12 Synthesizer Board
• A14 CPU/Motherboard
Each procedure consists of the following:
• A table listing the tests in the order they should be performed. The table also provides test conditions and expected
node voltages for each test.
• A block diagram of the assembly.
You Will Need Software
To perform the tests in this chapter you must use the service software that came with your signal generator.
The service software has a utility program that measures and displays the node voltages for each test. Refer
to your signal generator’s calibration guide for information on using the software.
Additional Block Diagrams
The following block diagrams can be found at the end of this chapter:
• AT1 Attenuator/RPP
• A7 Baseband Generator Board - Option 1EH
• A7 Baseband Generator Board - Options UN3 & UN4
• A8 Data Generator Board - Options UN3 & UN4
• Power Supply and Ground Interconnects
• Modulation & Signal Interconnects
