Query Errors
-410 Query INTERRUPTED
A command was received but the output buffer contained data from a 
previous command (the previous data is lost). 
-420 Query UNTERMINATED
The function generator was addressed to talk (i.e., to 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 an APPLy command 
(which does not generate data) and then attempted an “Enter” statement 
to read data from the 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. Example: *IDN?;:SYST:VERS?
