Error Checking
■
Error/event queue
The SCPI specifications define a standard error reporting scheme, Error/Event Queue
This is a FIFO (First In First Out) queue, which records errors and events. The maxi-
mum number of errors/events that the product can record is 16. Each error/event can
be read with the SYSTem:ERRor query.
SYSTem:ERRor?
The response to this query contains a numeric part (error/event number) and a textu-
al description, such as:
-222,"Data out of range"
The error/event queue becomes empty when the *CLS common command is sent,
when the last item in the queue is read, and when the product is turned on. When the
error/event queue is empty, the query returns the following:
0,"No error"
■
Displaying communication errors
The product has a debug trace function.
The product can display the oldest item among the errors and events (if there are er-
rors or events). This is convenient for debugging remote control.
When an error or event item is displayed on the panel, the normal voltmeter and am-
meter are void.
When the error/event queue is empty, the debug trace function does not display com-
munication errors.* When you send a CLS command, the communication error dis-
play clears.
In local mode, the debug trace function is temporarily disabled.
