TDS200/1000/2000 Series Oscilloscope Programmer Manual
Serial Poll
A device (such as an oscilloscope) on the GPIB bus can request
service from the GPIB Controller by asserting the GPIB SRQ
line (a Hardware line that is only present on the GPIB
communications bus). When a controller achnowledges the
SRQ, it ”serial polls” each open device on the bus to determine
which device on the bus requested service. Any device
requesting service returns a status byte with bit 6 set and then
unasserts the SRQ line. Devices not requiring service return a
status byte with bit 6 cleared.
