Standard SCPI errors (–1 to –999)
All positive numbers are instrument-dependent. All negative numbers are reserved by the SCPI
standard with certain standard error/event codes described in this document. The value, zero, is
also reserved to indicate that no error or event has occurred.
Error/event numbers
The system-defined error/event numbers are chosen on an enumerated (“1 of N”) basis. The
SCPI-defined error/event numbers and the <error/event description> portions of the full queue
item are listed here. The first error/event described in each class (for example, –100, –200,
–300, –400) is a “generic” error. In selecting the proper Error/event number to report, more spe-
cific error/event codes are preferred, and the generic error/event is used only if the others are
inappropriate.
Command errors
An <error/event number> in the range [–199, –100] indicates that an IEEE 488.2 syntax error
has been detected by the instrument’s parser. The occurrence of any error in this class shall
cause the command error bit (bit 5) in the event status register (IEEE 488.2, section 11.5.1) to be
set.
One of the following events has occurred:
• An IEEE 488.2 syntax error has been detected by the parser. That is, a controller-to-device mes-
sage was received which is in violation of the IEEE 488.2 standard. Possible violations include a
data element which violates the device listening formats or whose type is unacceptable to the de-
vice.
• An unrecognized header was received. Unrecognized headers include incorrect device-specific
