Agilent Technologies 4396B Gpib Programming Manual page 156

When both an external controller and Instrument BASIC are used at the same
Note
time, the
external controller queries the instrument while the 4396B is sweeping when
triggered by
normally (In the worst case, a system halt occurs).
To avoid this problem, it is necessary to use an SRQ interrupt technique that
uses the status register. In this case, the external controller waits to send query
commands until Instrument BASIC completes the execution of the
command.
