4.5 TYPICAL EXECUTION TIMES It takes about lmsec/bytefor theMode 3930A to receive
a command from the GPIB. The execution times given in
The execution times shown in Table 4-24 are the times re-
quired from the reception of ihe command until execu-
tion is complete. For inqu* messages, the execution
time is the time required from reception of the command
to the time when the output returns to the ready state.
These execution times are applicable only when a sweep
is not in progress. During a sweep, execution times may
increase by a factor of from several to one hundred times,
depending on the sweep condition.
the table are those for which the number of message char-
acters is the same as the number of characters returned by
the corresponding inquiry.
Ittakesabout 1.5msec/bytefor theModel3930A to trans-
fer data in the talker mode.
