C. Error Messages
A comprehensive syntax error occurred for which the 4294A could not detect further
details of the error. This error code simply indicates the occurrence of a command error
that is defined in IEEE488.2,11.5.1.1.4.
75 COMMAND IGNORED -SEGMENT NOT DONE YET
During the edit of a segment in the list sweep table or limit line table, an inappropriate edit
command (EDIT LIML, EDITLIST, LIMCLEL, LIMSEDI, LIMSADD, LIMSDEL,
SLEL, SEDI, SADD, SEGM) was sent and, as a result, the command was ignored. If
necessary, execute SDON (command to finish the edit of a list sweep segment), or
LIMSDON (command to finish the edit of a limit segment) to finish the edit of the segment,
and then perform the setting.
74 CURRENT EDITING SEGMENT SCRATCHED
During the edit of a segment in the list sweep table or limit line table, a key or command
not related to edit of the table was executed, and the segment that was being edited became
invalid. To avoid this, press “done key” in the segments menu, SDON (command to finish
the edit of a list sweep segment), or LIMSDON (command to finish the edit of a limit
segment), and then perform other settings.
D
91 DATA AND MEMORY TRACE NOT DISPLAYED
When both of the data trace and the memory trace were not displayed, you attempted to
change the setting of the data & memory couple (command: SCAC ON or SCAC
OFF). To
change the setting of the data & memory couple, first, display both of the data trace and the
memory trace (command: DISP
DATM).
-230 Data corrupt or stale
The data may be invalid. Or, a newly initiated read operation has not been completed since
the latest access.
-225 Data out of memory
To perform the requested operation, the 4294A does not have enough memory.
-222 Data out of range
A data element (that did not violate the standard) out of the range the 4294A defined was
received.
231 Data questionable
Data may be questionable. The accuracy of measurement data may be deteriorated.
93 DATA TRACE NOT DISPLAYED
When the data trace was not displayed, you attempted to set the function that needed the
display of the data trace and, as a result, the command was ignored. For example, a
command (MKRO DATA or SCAF DATA) corresponding to the MARKER ON [DATA] key
or the SCALE FOR [DATA] key was sent. Before setting the function that needs the
display of the data trace, display the data trace (command: DISP
DATA or DISP DATM).
-104 Data type error
The parser recognized impossible data elements. For example, numeric value or string data
was expected, but block data was sent.
