Error Messages

During normal operation, the MG3702xA generates error messages to indicate internal malfunctions, 
abnormal instrument operations, or invalid signal inputs or data entries. It also displays warning messages to 
alert the operator of conditions that could result in inaccurate MG3702xA output. In addition, status messages 
are displayed to remind the operator of current menu selections or settings.

System Self-Test

At power-on, the instrument performs a short self-test and reports errors that were encountered. A more 
comprehensive self-test performed under the System key (Self-Test / Run Self-Test) may be used for identifying 
system problems (excluding Windows-environment problems). The list of self-test errors and probable causes is 
found in 

Table 5-1 on page 5-3

. The error number will be displayed at the right of the screen, below is an 

example of an error.

If failures appear after manually performing a self-test, select 

OK | Advanced

. 

Note

Troubleshooting procedures in this chapter are intended to help identify and replace a failed part or 
assembly. The complex nature of this product may necessitate returning the MG3702xA to an 
Anritsu Service Center for some repairs and associated adjustments (calibrations).
