Infinity Representation
Infinity Representation
The representation for infinity for this oscilloscope is 9.99999E+37. This is also
the value returned when a measurement cannot be made.
Sequential and Overlapped Commands
IEEE 488.2 makes a distinction 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.
Response Generation
As defined by IEEE 488.2, query responses may be buffered for these reasons:
• When the query is parsed by the oscilloscope.
• When the computer addresses the oscilloscope to talk so that it may read the
response.
This oscilloscope buffers responses to a query when the query is parsed.
EOI
The EOI bus control line follows the IEEE 488.2 standard without exception.
