capability of the 3458A by letting it compute its own statistics, linearize its own
thermistors, or check its own limits while the controller is controlling other
instrumentation or is otherwise busy. The features of the 3458A dmm that make
this possible are the built-in math functions, the Reading Memory, State Memory
and Program Memory.
The time necessary to transfer measurements and commands to the computer is
computer dependent. GPIB turnaround time, the time to process OUTPUT and
ENTER operations will vary considerably from computer to computer. The features
of Program Memory, Reading Memory, State Storage, and post-processing math
operations all tend to decrease GPIB overhead and make the testing time far less
computer dependent.
