Appendix C: Error Messages
This appendix gives the error numbers and descriptions that are returned by the AC power
source. Error numbers are returned in two ways:
Error numbers are displayed on the front panel
Error numbers and messages are read back with the “SYSTem:ERRor?” query.
SYSTem:ERRor? returns the error number into a variable and returns two parameters: an
NR1 and a string.
When errors occur, the Standard Event Status register records them as shown in the following
table.
-300 thru -399
or
1 thru 799
Device-dependent
Note that errors over 800 do not set the ESR.
Standard Event Status register error bits
The following table lists the errors that are associated with SCPI syntax errors and interface
problems. It also lists the device dependent errors. Information inside the brackets is not part of
the standard error message, but is included for clarification.
Some error messages are maintained for back ward compatibility with Agilent/HP 6834B models.
