Query Error
Query Error
An error number in the range [-499 to -400] indicates that the output queue control
of the instrument has detected a problem with the message exchange protocol
described in IEEE 4888.2, chapter 6. The occurrence of any error in this class will
cause the query error bit (bit 2) to be set in the event status register (IEEE 488.2,
section 11.5.1). These errors correspond to message exchange protocol errors
described in IEEE 488.2, 6.5. If a query error occurs one of the following is true:
An attempt is being made to read data from the output queue when no output is either
present or pending.
Data in the output queue has been lost.
Events that generate query errors will not generate command errors, execution
errors, or device-specific errors; see the other error definitions in this section.
Query Error Message Descriptions
This section lists the signal generators query error messages and their associated
descriptions.

specific errors. The code indicates only that a query error as

Query INTERRUPTED
Indicates that a condition causing an INTERRUPTED query

sent.

Query UNTERMINATED
Indicates that a condition causing an UNTERMINATED query
error occurred (see IEEE 488.2, 6.3.2.2). For example, the
device was addressed to talk and an incomplete program
message was received.
