SCPI Error Messages

SCPI Error Messages
The Agilent instrument returns error messages in accord with the SCPI standard.
Up to 20 errors can be stored in each interface-specific error queue (one each for GPIB, USB, VXI-11, and Tel-
l
net/Sockets.) Errors appear in the error queue of the I/O session that caused the error.
The instrument beeps once each time a command syntax or hardware error is generated. The front-panel ERROR
l
annunciator turns on when one or more errors are in the error queue.
A special global error queue holds all power-on and hardware-related errors (for example, over-temperature).
l
Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them. Once you have read all interface-
l
specific errors, the errors in the global error queue are retrieved. When you have read all errors from the error
queue, the ERR annunciator turns off.
If more than 20 errors have occurred, the last error stored in the queue (the most recent error) is replaced with -
l
350,"Error queue overflow". No additional errors are stored until you remove errors from the queue. If no errors
have occurred when you read the error queue, the instrument responds with +0,"No error".
The front panel reports errors from all I/O sessions and the global error queue. To read the error queue from the
l
front panel, press the SYSTEM button, then the "Help" softkey. Then select "View remote command error queue"
in the Help menu.
Error conditions are also summarized in the Status Byte Register. See
l
The interface-specific error queues are cleared by power cycles and *CLS. The error queue is not cleared by *RST.

SYSTem:ERRor?
Errors have the following format (the error string may contain up to 255 characters):
-113,"Undefined header"
Error Device-dependent Errors (these errors set Standard Event Status register bit #3)
0 No error
This is the response to the ERR? query when there are no errors.
101 Calibration state is off
Calibration is not enabled. The instrument will not accept calibration commands.
102 Calibration password is incorrect
The calibration password is incorrect.
103 Calibration is inhibited by switch setting
Calibration mode is locked out by the calibration switch.
104 Bad sequence of calibration commands
Calibration commands have not been entered in the proper sequence.
116 Locked out by internal switch setting
This function has been locked out by an internal switch.
200 Hardware error channel <1>
110
