incomplete program messages. For example, when a command that does not require a
Query, such as "*CLS", has been sent as "*CLS?", it is regarded as an incomplete message
by the E4991A.
Check the command reference.
-440 Query UNTERMINATED after indefinite response
This indicates that a query has been received in the same program message after a query
requesting an indefinite response has been executed (refer to IEEE488.2, 6.5.7.5.7).
R
105 Recall error
An error has occurred during reading out (recall) of a file. For example, this occurs when
an attempt is made to read out a file containing invalid data (such as the extension (.sta) for
instrument state files that were saved with equipment other than the E4991A).
Confirm that there is no problem in the file contents.
S
104 Save error
While saving a file, an error has been detected on the media in which the data is to be
stored. For example, when saving the file to a floppy disk, the space available in the floppy
disk is not sufficient.
Check the amount of available space in the media in which the date is to be stored.
118 Segment table empty or insufficient table
Because the segment sweep table has not been created, a sent command has been ignored.
For example, before the segment sweep table is created, the SWE:TYPE command is
attempted in order to set a sweep type as the segment sweep.
Before carrying out a segment sweep, create the segment sweep table.
-221 Settings conflict
Even though the program data element has been received and it conforms to the standard,
execution is not possible with the present condition of the E4991A.
-150 String data error
An error caused by a received series of character data elements (quotation mark character)
has occurred. In errors - 151 to - 159, an unspecified character string error has occurred.
-158 String data not allowed
A string data element has been found at a position where the E4991A does not allow string
data elements. For example, when the program message "TRIG:SOUR "MAN"" has
been sent instead of the correct program message "TRIG:SOUR MAN", the double quote
(") is regarded by the E4991A as invalid.
Refer to the command reference and confirm whether the double quote (") is required in
the parameter of a particular command.
-138 Suffix not allowed
A suffix has been added after numeric data where a suffix (here meaning Unit) cannot be
