Set GPIB address (8) in a variable.
Set in the single sweeping mode.
Make the Sweep-end bit of the
operation status register enable.
Clear the status byte.
Begin the sweeping.
Request the output of the status byte.
Read the status byte.
Wait until the operation status bit
(end of sweeping) is set in one.
Example HP-16: Execute ACP measurement and begin reading the result after the measurement is
ended (when not using SRQ signal).
