Error Conditions
When the front-panel ERROR annunciator turns on, one or more
command syntax or hardware errors have been detected. A record of
up to 10 errors is stored in the instrument’s error queue. See chapter 6
for a complete listing of the errors.
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. When you have read all errors from the queue, the
ERROR
annunciator turns off and the errors are cleared. The instrument
beeps once each time an error is generated.
If more than 10 errors have occurred, the last error stored in the
queue (the most recent error) is replaced with “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 “No error”.
The error queue is cleared by the *CLS (clear status) command or
when power is cycled. The errors are also cleared when you read the
queue. The error queue is not cleared by a Factory Reset (*RST
command) or an Instrument Preset (SYSTem:PRESet command).
