ERRor?
SYSTem:ERROR? returns the error messages in the error queue. See Appendix B
for a listing of the digitizer error numbers and messages.
Comments • As errors are detected, they are placed in the error queue. The queue is first-in,
first out, meaning that if several error messages are waiting in the queue,
SYSTem:ERRor? returns the oldest unread error message.
• The error queue can hold 30 error messages. If more than 30 messages are
generated without being read, the last error message in the queue is replaced with
error -350,"Too many errors". No additional messages are placed into the queue
until SYSTem:ERRor? reads some messages or until the queue is cleared using
the *CLS (clear status) command.
• When the error queue is empty, SYSTem:ERRor? returns +0,"No error".
• *RST Condition: unaffected
• Power-On Condition: no errors are in the error queue
Example Reading the error queue

:VERSion?
SYSTem:VERSion? returns the SCPI version number to which the
HP E1429A/B complies: "1992.0".
Example Querying the SCPI revision
