SYSTem:ERRor?
Read and clear one error from the function generator’s error queue.
A record of up to 20 command syntax or hardware errors can be stored in
the error queue. See chapter 5 for a complete listing of the error messages.
• Errors are retrieved in first-in-first-out (FIFO) order. The first error
returned is the first error that was stored. Errors are cleared as you
read them. The function generator beeps once each time an error is
generated (unless disabled using the
SYST:BEEP:STAT
command)
.
• If more than 20 errors have occurred, the last error stored in the
queue (the most recent error) is replaced with “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 function generator responds with “No error”.
• The error queue is cleared by the *CLS (clear status) command or
when the power is cycled. The errors are also cleared when you read
the queue. The error queue is not cleared by a reset (*RST command).
• Errors have the following format (the error string may contain up to
255 characters).
