To troubleshoot the oscilloscope
The troubleshooting procedure is used to isolate problems to a faulty assembly. When
you find the faulty assembly, use the disassembly and assembly procedures in chapter
6 to replace the assembly.
The primary procedural tool in this section is the flowchart. The flowchart contains the
entire troubleshooting path from a failed oscilloscope to a working one, and will direct
you in an orderly manner through the possible failure symptoms. Reference letters on
the flowcharts point to procedural steps that explain the brief instructions in the chart.
Do not try to troubleshoot by following only the reference text because the text is not
in the correct order for troubleshooting. Instead, simply follow the flowchart.
If you are unfamiliar with this oscilloscope, start with the Primary Trouble Isolation
Flowchart on the next page.
