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