Execution Errors

-350 Error queue overflow
The error queue is full because more than 10 errors (34970A) or 20 errors
(34972A) have occurred. No additional errors are stored until you remove
errors from the queue. The error queue is cleared by the *CLS (clear
status) command or when power is cycled. The errors are also cleared
when you read the queue.
-410 Query INTERRUPTED
A command was received which sends data to the output buffer, but the
output buffer contained data from a previous command (the previous
data is not overwritten). The output buffer is cleared when power has
been off or after a bus Device Clear.
-420 Query UNTERMINATED
The instrument was addressed to talk (i.e., send data over the interface)
but a command has not been received which sends data to the output
buffer. For example, you may have executed a CONFigure command
(which does not generate data) and then attempted to read data from the
remote interface.
-430 Query DEADLOCKED
A command was received which generates too much data to fit in the
output buffer and the input buffer is also full. Command execution
continues but all data is lost.
-440 Query UNTERMINATED after indefinite response
The *IDN? command must be the last query command within a
command string. The *IDN? command returns an indefinite length
string which cannot be combined with any other query command.
Example: *IDN?;*STB?
