SYSTem:ERRor?
Syntax
SYSTem:ERRor?
This command reads and clears one error from the instrument's error
queue. A record of up to 20 errors can be stored in the U3606A error
queue.
For SCPI command errors, this command returns the following format
string:
<Number,"Error String">
The error string may contain up to 255 characters and consists of an
error number and an error string enclosed in double quotes.
For example:
-113,"Undefined header"
Errors are retrieved in a first- in- first- out (FIFO) order. The first error
returned is the first error that was stored. Reading this error will clear
this error allowing the next error to be read (if there are other errors
stored).
Remarks
•
The U3606A beeps once each time a command syntax or hardware
error occurs.
•
If more than 20 errors have occurred, the last error stored in the queue
(the most recent error) is replaced with error number
-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"
.
•
Error conditions are also summarized in the Status Byte register.
•
The error queue is cleared by the clear status (
*CLS
) command (for I/O
session), and when power is cycled (for all errors). However, the error
queue will not be cleared by a factory reset (
*RST
) command.
