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 you have disabled the beeper).
• 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 error queue. The error queue is not cleared by an instrument reset
(*RST command).
• Front-Panel Operation: Press
"View the remote command error queue" (topic number 2). Then press
the SELECT softkey to view the errors in the error queue. As shown
below, the first error in the list (i.e., the error at the top of the list) is
the first error that was generated.
• Remote Interface Operation:
SYSTem:ERRor?
Errors have the following format (the error string may contain up to
255 characters).
-113,"Undefined header"
Note: Some error numbers can have several causes. The descriptive
string begins with a fixed portion that is common to all errors with the
same number. In many cases, additional, situation-dependent
information appears after a semicolon (";"). For example, there are several
causes for error -221. Here is an example:
-221,"Settings conflict; burst count reduced"
284
and then select the topic entitled
