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 U3606B 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).
