• For analyzers with Options 146 and 246, traces A, B, C, D, R1, and R3 are displayed in six separate data
windows as shown in Figure 4-8. Identifying discrepancies of the traces in these windows can help you
to isolate the faulty assembly.

• If all traces are present and are similar to the traces in Figure 4-7 or Figure 4-8, then there are no major
problems with the analyzer’s measurement system. There may, however, be a minor failure in the
analyzer.
To test f u r ther :
—Go to Chapter 3, “Tests and Adjustments” and perform all the tests in that section.
— If a problem still exists, contact Agilent. Refer to “Contacting Agilent” on page 2-11.
• If any of the traces are not present, are noisy or distorted, or are at an incorrect level, then there is a
problem with the analyzer’s measurement system. Proceed to “Where to Begin Troubleshooting.”
