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 20 errors can be stored in the function generator’s error queue.
See chapter 5, “Error Messages,” 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. When you have read all
errors from the queue, the
ERROR annunciator turns off. The function
generator beeps once each time an error is generated.
• If more than 20 errors have occurred, the last error stored in the
queue (the most recent error) is replaced with -350, “Too many errors”.
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 +0, “No error”.
• The error queue is cleared when power has been off or after a *CLS
(clear status) command has been executed. The *RST (reset)
command does not clear the error queue.
• Front-Panel Operation:
3: ERROR (SYS MENU)
If the
ERROR annunciator is on, press Shift < (Recall Menu) to read
the errors stored in the queue. The errors are listed horizontally on
the “
PARAMETER” level. All errors are cleared when you go to the
“
PARAMETER” level and then turn off the menu.
• Remote Interface Operation:
SYSTem:ERRor?
Reads one error from the error queue
Errors have the following format (the error string may contain
up to 80 characters):
-113,"Undefined header"
ERR 1: -113
Error code First error in queue
