–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 turned off, or after the *RST (reset) command has been executed.
–420 Query UNTERMINATED
The U8480 Series was addressed to talk (that is, 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 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 data is lost.
–440 Query UNTERMINATED after indefinite response
The *IDN? command must be the last query command within a command string.
