Timing Behavior

Table 15 details the ways in which timing behavior is different.

Table 15 Timing Behavior Changes

Change Affects

Command execution may be different. Both

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.

Both

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.
