2 Query Error 1. Set to “1” when the E5061A/E5062A receives a data
output request but there is no data to output.
2. Set to “1” when the data of the E5061A/E5062A's
output queue has been cleared because of a new
message received before the completion of data
output.
3 Instrument Dependent Error Set to “1” when an error has occurred and the error is not a
command, query, or execution error.

unacceptable.
2. Set to “1” when a semantic error occurs. Possible
