SYSTem:ERRor?
Reads and clears one error from the error queue. See SCPI Error Messages for the complete SCPIerror message list.
Parameter Typical return
(none) <error code>,<error string>
Read and clear the first error in the error queue: SYST:ERR?
– Up to 20 errors can be stored in the instrument's error queue. Each remote interface I/O session (USB, VXI-11,
Telnet/Sockets) has its own interface-specific error queue. Errors appear in the error queue of the I/O session
that caused the error.
– Error retrieval is first-in-first-out (FIFO), and errors are cleared as you read them. The instrument beeps each time
an error is generated (unless disabled by SYSTem:BEEPer:STATe OFF).
– If more than 20 errors have occurred, the most recent error stored in the queue is replaced with -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".
– Errors have the following format (the error string may contain up to 255 characters).
<error code>,<error string>
Where:
<error code> = a positive or negative integers
<error string> = a quoted ASCII string up to 255 characters
– Error conditions are also summarized in the Status Byte Register. For more information, see STATus Subsystem.
