7-4-3-2 Full RFI Test (cont’d)
NOTE: For the Full RFI test, four tests are performed in the test sequence; these are listed in the Tests
window as shown in Figure 7-13. For each currently-selected test (for example, RFI FE Cache
Test) the corresponding report is listed in Reports on the right.
For details of each report, refer to the following explanations:
- Figure 7-15 "View Test Log - RFI Cache Test" on page 7-37
- Figure 7-19 "View Test Log - RFI Demodulator Short Test" on page 7-43
- Figure 7-17 "View Test Log - RFI Analog Circuits Test" on page 7-40
- Figure 7-21 "View Test Log - RFI Audio Test" on page 7-46
9) When done, trackball to the Exit button and press Set to close the View Report window.
10) After reviewing the test results, proceed as follows:
• If no problems were identified, it is recommended to re-boot the system (this is obligatory when
prompted).
• If no problems were identified but the problem persists, contact your local GE HEALTHCARE
field engineer for assistance.
• If errors were identified but the results were marginal, perform calibration, as described in
“DC Offset Calibration” on page 7-27, and then repeat the test.
• If errors were identified and the results were not marginal, verify that all system cables and
boards are connected (not misplaced) and functioning properly, as described in Chapter 5 -
Components and Function (Theory).
If the problem persists, this indicates that either the specific board you tested is faulty or that
another board that supports the operation of that board is faulty. Contact your local
GE HEALTHCARE field engineer for assistance.
