Parallel Poll Response Checkbox

The Parallel Poll Responses checkbox enables the GPIB analyzer to capture all GPIB parallel poll responses. To delimit the beginning of a GPIB parallel poll, the analyzer captures the assertion of ATN and EOI. The next capture, after 2 µs, denotes the beginning of the parallel poll response. The analyzer then captures data each time the response on a GPIB data line changes. To delimit the end of a GPIB parallel poll, the analyzer captures the point at which EOI is unasserted.
