Power Module Hardware Error Messages

Front panel error messages resulting from selftest errors or runtime failures are described in the power module User’s
Guide.

System Error Messages

System error messages are read back via the SYST:ERR? query. The error number is the value placed in the power module
error queue. SYST:ERR? returns the error number into a variable and combines the number and the error message into a
string. Table 6-1 lists the system errors that are associated with SCPI syntax errors and interface problems. Information
inside the brackets is not part of the standard error message, but is included for clarification. When system errors occur, the
Standard Event Status register (see "Chapter 4 - Status Reporting") records them as follows:
Standard Event Status Register Error Bits
Bit Set Error Code Error Type Bit Set Error Code Error Type
5-100 thru -199 Command 3-300 thru -399 Device-dependent
4-200 thru -299 Execution 2-400 thru -499 Query
