Error Messages
If an error condition occurs in the signal generator, it is reported to both the front panel display error queue
and the SCPI (remote interface) error queue. These two queues are viewed and managed separately; for
information on the SCPI error queue, refer to the E4428C/38C ESG Signal Generators Programming Guide.
NOTE When there is an unviewed message in the front panel error queue, the ERR annunciator
appears on the signal generator’s display.
Error Message File
A complete list of error messages is provided in the file errormessages.pdf, on the CDROM 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.
