Command execution may be different.

In all mainframes and modules firmware revisions before 3.x GPIB will
block during command execution, except when executing functions,
such as logging and sweep, that don’t tolerate blocking. This is
identical to the behavior of the 8167/8. A side effect of this is that
*OPC? always returns 1.

In later firmware revisions GPIB only blocks if a command can't be
processed because of a pending command. While a command is
pending *OPC? returns 0 now. This is the behaviour of the 8153.

When continuous triggering and averaging times are greater than 1
second, the read-out values reset after the averaging time is over; there
is no sliding behavior.
