Error - HP 16500C Programmer's Manual

ERRor

Query :SYSTem:ERRor? [NUMeric|STRing]
The ERRor query returns the oldest error from the error queue. The optional
parameter determines whether the error string should be returned along with
the error number. If no parameter is received, or if the parameter is
NUMeric, then only the error number is returned. If the value of the
parameter is STRing, then the error is returned in the following form:
<error_number>,<error message string>
A complete list of error messages for the HP 16500C logic analysis system is
shown in chapter 8, "Error Messages." If no errors are present in the error
queue, a zero (No Error) is returned.
