Infinity Representation
The representation of infinity is 9.9E+37. This is also the value returned
when a measurement cannot be made.
Sequential and Overlapped Commands
IEEE 488.2 distinguishes between sequential and overlapped commands.
Sequential commands finish their task before the execution of the next
command starts. Overlapped commands run concurrently. Commands
following an overlapped command may be started before the overlapped
command is completed. All of the commands are sequential.
Response Generation
As defined by IEEE 488.2, query responses may be buffered for the following
conditions:
When the query is parsed by the instrument.
When the controller addresses the instrument to talk so that it may read
the response.
The responses to a query are buffered when the query is parsed.
