Error Messages
Error Messages
If an error condition occurs in the signal generator, it is reported to both the SCPI (remote interface)
error queue and the front panel display error queue. These two queues are viewed and managed
separately; for information on the front panel display error queue, refer to the User’s Guide.
NOTE For additional general information on troubleshooting problems with your connections, refer
to the Help in the Agilent IO Libraries and documentation.
When accessing error messages using the SCPI (remote interface) error queue, the error numbers and
the <error_description> portions of the error query response are displayed on the host terminal.
Error Message File
A complete list of error messages is provided in the file errormessages.pdf, on the CD-ROM supplied
with your instrument. In the error message list, an explanation is generally included with each error
to further clarify its meaning. The error messages are listed numerically. In cases where there are
multiple listings for the same error number, the messages are in alphabetical order.
