When a checksum error occurs, you can take either of the following actions:
• Choose the interactive softkey that is adjacent to “Reset Memory.” In this case, NVRAM is reset.
• Choose the interactive softkey that is adjacent to “Ignore.” In this case, NVRAM is not reset, but the
checksum is recalculated. This allows you to continue using the instrument with the current contents
of NVRAM intact, but you might encounter abnormal instrument operation.
B.3 Remote Error Messages
Commands including SCPI, GPIB, or register commands issued to 2500A may fail to execute. There are
several reasons for the failure, such as wrong command string, wrong number of parameters, invalid
parameter values, or invalid operation mode. This section defines the error codes and error strings for
each possible failure. When an error occurs, the 2500A will queue the errors to an internal event buffer.
When using the GPIB interface, a 2500A will send a service request to the controller and the controller
software is responsible for querying the status message. When using the RS232 interface, the controller
software should poll the 2500A for the error condition. A user can also query the 2500A using the ERR?
query (GT12000 language mode) or SYStem:ERR? (SCPI language mode).
The message structure is {error #, 2500A error message}
Table B-2 describes the 2500A remote error messages.
