TROUBLESHOOTING

SYSTEM HAS ERROR CODE

System error codes in the range 0100 - 3999 identify the suspected failed subassembly in the two most-significant digits of the error code. For example: error codes 0200 - 0299 are related to the A2, LO2 PCB assembly. This error code assignment scheme allows for quick identifi- cation of suspect assemblies.

NOTE

Refer to Appendix B, Error Codes/Messages, for a list of the error codes/messages for 37300A VNA systems.

There are cases when a fault on one assembly will cause a different as- sembly to be identified as faulty (per the error code designated). This happens when a failure occurs on an assembly that provides a stimu- lus or a calibration signal to other assemblies in the system. Example: the A7 LO3 PCB provides the IF Calibration signal to the A3, A4, and A6 PCB’s. If the IF Cal signal is faulty, error codes will be reported for the A3, A4, A6, and A7 PCB’s.

NOTE

An aide to troubleshooting system failures using error codes is a good understanding of system and subassembly operation. Refer to the descriptions of system and subas- sembly operation and block diagrams located in Chapter 7, System Description.

Self TestError Codes Error codes 0100 - 3999, with few exceptions, are produced as a result of a failure when the system self test is run. These error codes will not be displayed on the CRT screen. Only the overall result of the self test (PASS/FAIL) will be displayed at the conclusion of the self test. How- ever, any error codes due to the self test will be written to the service log as the self test is executed.

NOTE

The exceptions are error codes with 00 in the two least-significant digits, for example: 0500 A/D CONVER- SION FAIL. These errors are produced at run time if a problem is encountered when the system is actively mak- ing measurements.

Phase Lock Error The Phase Lock error codes (6000 - 6999) will have an alphabetical Codes (6000 Series) suffix (code) following the message. For example: 6079 PHS LCK FAIL

ABCDG. This code consists of one or more letters from A - G that rep- resent the sub assembly that was not locked and/or the nature of the failure. The phase lock failure mode suffixes are listed in Table 5-2.

Note that most phase lock error codes will normally consist of a letter identifying the unlocked assembly and the D and/or DE letters that indicate the Source Module is also unlocked. This is normal since all components in the phase lock loop must be correctly locked in order for
