the minimum frequency and the maximum frequency, respectively, within all segments)
with the LIST SPAN [ ] key or the LISPAN SINGLE command and, as a result, the
command is ignored. When executing the list sweep when the sweep span of each segment
is set to zero, the list sweep span is automatically set to the segment span and cannot be
changed.
114 CAN'T SAVE GRAPHICS WHEN COPY IN PROGRESS
You want to execute a command to save the graphics screen during copying (outputting to
a printer), but the graphics screen cannot be saved during printing.
-140 Character data error
An error not described by error numbers from -141 to -149 occurs during the syntax
analysis of a character data element.
-148 Character data not allowed
A character data element (that does not violate the standard) is received where the Agilent
4294A does not accept any character data element. For example, a parameter must be
enclosed with double quotation marks (") but they are missing.
-144 Character data too long
The length of the character data element exceeds 12 characters. (Refer to
IEEE488.2,7.7.1.4.)
-100 Command error
A comprehensive syntax error occurs for which the Agilent 4294A cannot 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 editing 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) is sent and, as a result, the command is ignored. If necessary,
execute SDON (command to finish the editing of a list sweep segment), or LIMSDON
(command to finish the editing of a limit segment) to finish the editing of the segment and
then perform the setting.
74 CURRENT EDITING SEGMENT SCRATCHED
During the editing of a segment in the list sweep table or limit line table, a key or command
not related to edit of the table is executed, and the segment being edited becomes invalid.
To avoid this, press the "done key" in the segments menu, SDON (command to finish the
editing of a list sweep segment), or LIMSDON (command to finish the editing of a limit
segment) and then perform other settings.
91 DATA AND MEMORY TRACE NOT DISPLAYED
While the data trace and memory trace are not both displayed, you attempt 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 the data trace and the memory trace
(command: DISP DATM).
