-400 Query error
A comprehensive query error has occurred showing that this instrument cannot detect a
more detailed error. This code simply shows that a query error defined in 11.5.1.1.7 and
6.3, IEEE488.2 has occurred.
-410 Query INTERRUPTED
The state that generates a "INTERRUPTED" Query error (see 6.3.2.3, IEEE488.1). This
error occurs when data bytes (DAB) or GET are received before the transmission of the
response after a query has not been completed, for example.
-420 Query UNTERMINATED
The state that generates an "UNTERMINATED" Query error (see 6.3.2, IEEE488.2). This
error occurs when this instrument is designated as the talker and an incomplete program
message is received, for example.
-440 Query UNTERMINATED after indefinite response
After a query asking for an indefinite response has been run, another query is received in
the same program message (See 6.5.7.5.7, IEEE488.2).
R
105 Recall failed
This error occurs when reading an instrument status file (State01.sta, etc.)
(MMEM:LOAD:STAT command) fails.
S
106 Save failed
This error occurs when writing an instrument status file (State01.sta, etc.)
(MMEM:STOR:STAT command) fails.
50 Specified channel hidden
This error occurs when an attempt is made to activate a channel not on display using the
DISP:WIND:ACT command. This error is not generated by front key operations.
21 Specified ports overlapped
This error occurs when a port number is duplicated in a command requiring two or more
port numbers as parameters. Such commands are, for example,
CALC:FSIM:BAL:TOP:SSB:PPOR 1,2,3,3. Specify port setup correctly to avoid
duplication of ports. This error is not generated by front key operations.
-150 String data error
When a character-string-data element is put to syntactic analysis, an error not
corresponding to one of Error Numbers -151 through -159 occurs.
-158 String data not allowed
A character-string-data element has been received at a position where this instrument does
not accept one.
