12.2 Error Messages in Remote Control Mode
In remote control mode error messages are entered in the error/event queue of the sta-
tus reporting system and can be queried with the command SYSTem:ERRor?. The
answer format of R&S FPL1000 to the command is as follows:
<error code>, "<error text with queue query>; <remote control
command concerned>"
The indication of the remote control command with prefixed semicolon is optional.
Example:
The command TEST:COMMAND generates the following answer to the query
SYSTem:ERRor?
-113,"Undefined header;TEST:COMMAND"
There are two types of error messages:
●
Error messages defined by SCPI are marked by negative error codes. These mes-
sages are defined and described in the SCPI standard and not listed here.
●
Device-specific error messages use positive error codes. These messages are
described below.
